Reupload

- Add cache refresh mechanism for config updates
- Implement selective re-initialization for NIP-11 relay info changes
- Categorize configs as dynamic vs restart-required using requires_restart field
- Enhance admin API responses with restart requirement information
- Add comprehensive test for dynamic config updates
- Update documentation for dynamic configuration capabilities

Most relay settings can now be updated via admin API without requiring restart, improving operational flexibility while maintaining stability for critical changes.

+
+**Project-Specific Information for AI Agents Working with C-Relay in Architect Mode**
+
+## Critical Architecture Understanding
+
+### System Architecture Overview
+C-Relay implements a **unique event-based configuration architecture** that fundamentally differs from traditional Nostr relays:
+
+```

+
+### Core Architectural Principles
+
+#### 1. Event-Driven Configuration
+**Design Philosophy**: Configuration as cryptographically signed events rather than files
+- **Benefits**: Auditability, remote management, tamper-evidence
+- **Trade-offs**: Complexity in configuration changes, admin key management burden
+- **Implementation**: Kind 33334 events stored in same database as relay events
+
+#### 2. Identity-Based Database Naming
+**Design Philosophy**: Database file named by relay's generated public key
+- **Benefits**: Prevents database conflicts, enables multi-relay deployments
+- **Trade-offs**: Cannot predict database filename, complicates backup strategies
+- **Implementation**: `<relay_pubkey>.db` created in build/ directory
+
+#### 3. Single-Binary Deployment
+**Design Philosophy**: All functionality embedded in one executable
+- **Benefits**: Simple deployment, no external dependencies to manage
+- **Trade-offs**: Larger binary size, harder to modularize
+- **Implementation**: SQL schema embedded as header file, nostr_core_lib as submodule
+
+#### 4. Dual-Protocol Support
+**Design Philosophy**: WebSocket (Nostr) and HTTP (NIP-11) on same port
+- **Benefits**: Simplified port management, reduced infrastructure complexity
+- **Trade-offs**: Protocol detection overhead, libwebsockets dependency
+- **Implementation**: Request routing based on HTTP headers and upgrade requests
+
+## Architectural Decision Analysis
+
+### Configuration System Design
+**Traditional Approach vs C-Relay:**
+```
+Traditional:           C-Relay:
+config.json     →     kind 33334 events
+ENV variables   →     cryptographically signed tags
+File watching   →     database polling/restart
+```
+
+**Implications for Extensions:**
+- Configuration changes require event signing capabilities
+- No hot-reloading without architectural changes
+- Admin key loss = complete database reset required
+
+### Database Architecture Decisions
+**Schema Design Philosophy:**
+- **Event Tags as JSON**: Separate table with JSON column instead of normalized relations
+- **Application-Level Filtering**: NIP-40 expiration handled in C, not SQL
+- **Embedded Schema**: Version 4 schema compiled into binary
+
+**Scaling Considerations:**
+- SQLite suitable for small-to-medium relays (< 10k concurrent connections)
+- Single-writer limitation of SQLite affects write-heavy workloads
+- JSON tag storage optimizes for read performance over write normalization
+
+### Memory Management Architecture
+**Thread Safety Model:**
+- Global subscription manager with mutex protection
+- Per-client subscription limits enforced in memory
+- WebSocket connection state managed by libwebsockets
+
+**Resource Management:**
+- JSON objects use reference counting (jansson library)
+- String duplication pattern for configuration values
+- Automatic cleanup on client disconnect
+
+## Architectural Extension Points
+
+### Adding New Configuration Options
+**Required Changes:**
+1. Update [`default_config_event.h`](src/default_config_event.h) template
+2. Add parsing logic in [`config.c`](src/config.c) `load_config_from_database()`
+3. Add global config struct field in [`config.h`](src/config.h)
+4. Update documentation in [`docs/configuration_guide.md`](docs/configuration_guide.md)
+
+### Adding New NIP Support
+**Integration Pattern:**
+1. Event validation in [`request_validator.c`](src/request_validator.c)
+2. Protocol handling in [`main.c`](src/main.c) WebSocket callback
+3. Database storage considerations in schema
+4. Add test in `tests/` directory
+
+### Scaling Architecture
+**Current Limitations:**
+- Single process, no horizontal scaling
+- SQLite single-writer bottleneck
+- Memory-based subscription management
+
+**Potential Extensions:**
+- Redis for subscription state sharing
+- PostgreSQL for better concurrent write performance
+- Load balancer for read scaling with multiple instances
+
+## Deployment Architecture Patterns
+
+### Development Deployment
+```
+Developer Machine:
+├── ./make_and_restart_relay.sh
+├── build/c_relay_x86
+├── build/<relay_pubkey>.db
+└── relay.log
+```
+
+### Production SystemD Deployment
+```
+/opt/c-relay/:
+├── c_relay_x86
+├── <relay_pubkey>.db
+├── systemd service (c-relay.service)
+└── c-relay user isolation
+```
+
+### Container Deployment Architecture
+```
+Container:
+├── Multi-stage build (deps + binary)
+├── Volume mount for database persistence
+├── Health checks via NIP-11 endpoint
+└── Signal handling for graceful shutdown
+```
+
+### Reverse Proxy Architecture
+```
+Internet → Nginx/HAProxy → C-Relay
+                       ├── WebSocket upgrade handling
+                       ├── SSL termination
+                       └── Rate limiting
+```
+
+## Security Architecture Considerations
+
+### Key Management Design
+**Admin Key Security Model:**
+- Generated once, displayed once, never stored
+- Required for all configuration changes
+- Loss requires complete database reset
+
+**Relay Identity Model:**
+- Separate keypair for relay identity
+- Public key used for database naming
+- Private key never exposed to clients
+
+### Event Validation Pipeline
+```
+WebSocket Input → JSON Parse → Schema Validate → Signature Verify → Store
+                             ↓                 ↓                  ↓
+                    reject    reject          reject           success
+```
+
+### Attack Surface Analysis
+**Network Attack Vectors:**
+- WebSocket connection flooding (mitigated by libwebsockets limits)
+- JSON parsing attacks (handled by jansson library bounds checking)
+- SQLite injection (prevented by prepared statements)
+
+**Configuration Attack Vectors:**
+- Admin key compromise (complete relay control)
+- Event signature forgery (prevented by nostr_core_lib validation)
+- Replay attacks (event timestamp validation required)
+
+## Non-Obvious Architectural Considerations
+
+### Database Evolution Strategy
+**Current Limitations:**
+- Schema changes require database recreation
+- No migration system for configuration events
+- Version 4 schema embedded in binary
+
+**Future Architecture Needs:**
+- Schema versioning and migration system
+- Backward compatibility for configuration events
+- Database backup/restore procedures
+
+### Configuration Event Lifecycle
+**Event Flow:**
+```
+Admin Signs Event → WebSocket Submit → Validate → Store → Restart Required
+                                    ↓            ↓         ↓
+                              Signature Check   Database  Config Reload
+```
+
+**Architectural Implications:**
+- No hot configuration reloading
+- Configuration changes require planned downtime
+- Event ordering matters for multiple simultaneous changes
+
+### Cross-Architecture Deployment
+**Build System Architecture:**
+- Auto-detection of host architecture
+- Cross-compilation support for ARM64
+- Architecture-specific binary outputs
+
+**Deployment Implications:**
+- Binary must match target architecture
+- Dependencies must be available for target architecture
+- Debug tooling architecture-specific
+
+### Performance Architecture Characteristics
+**Bottlenecks:**
+1. **SQLite Write Performance**: Single writer limitation
+2. **JSON Parsing**: Per-event parsing overhead
+3. **Signature Validation**: Cryptographic operations per event
+4. **Memory Management**: JSON object lifecycle management
+
+**Optimization Points:**
+- Prepared statement reuse
+- Connection pooling for concurrent reads
+- Event batching for bulk operations
+- Subscription indexing strategies
+
+### Integration Architecture Patterns
+**Monitoring Integration:**
+- NIP-11 endpoint for health checks
+- Log file monitoring for operational metrics
+- Database query monitoring for performance
+- Process monitoring for resource usage
+
+**Backup Architecture:**
+- Database file backup (SQLite file copy)
+- Configuration event export/import
+- Admin key secure storage (external to relay)
+
+### Future Extension Architectures
+**Multi-Relay Coordination:**
+- Database sharding by event kind
+- Cross-relay event synchronization
+- Distributed configuration management
+
+**Plugin Architecture Possibilities:**
+- Event processing pipeline hooks
+- Custom validation plugins
+- External authentication providers
+
+**Scaling Architecture Options:**
+- Read replicas with PostgreSQL migration
+- Event stream processing with message queues
+- Microservice decomposition (auth, storage, validation)
+
+## Architectural Anti-Patterns to Avoid
+
+1. **Configuration File Addition**: Breaks event-based config paradigm
+2. **Direct Database Modification**: Bypasses signature validation
+3. **Hard-Coded Ports**: Conflicts with auto-fallback system
+4. **Schema Modifications**: Requires database recreation
+5. **Admin Key Storage**: Violates security model
+6. **Blocking Operations**: Interferes with WebSocket event loop
+7. **Memory Leaks**: JSON objects must be properly reference counted
+8. **Thread Unsafe Operations**: Global state requires proper synchronization
+
+## Architecture Decision Records (Implicit)
+
+### Decision: Event-Based Configuration
+**Context**: Traditional config files vs. cryptographic auditability
+**Decision**: Store configuration as signed Nostr events
+**Consequences**: Complex configuration changes, enhanced security, remote management capability
+
+### Decision: SQLite Database
+**Context**: Database choice for relay storage
+**Decision**: Embedded SQLite with JSON tag storage
+**Consequences**: Simple deployment, single-writer limitation, application-level filtering
+
+### Decision: Single Binary Deployment
+**Context**: Dependency management vs. deployment simplicity
+**Decision**: Embed all dependencies and schema in binary
+**Consequences**: Larger binary, simple deployment, version coupling
+
+### Decision: Dual Protocol Support
+**Context**: WebSocket for Nostr, HTTP for NIP-11
+**Decision**: Same port serves both protocols
+**Consequences**: Simplified deployment, protocol detection overhead, libwebsockets dependency
+
+These architectural decisions form the foundation of C-Relay's unique approach to Nostr relay implementation and should be carefully considered when planning extensions or modifications.

+# AGENTS.md - AI Agent Integration Guide
+
+**Project-Specific Information for AI Agents Working with C-Relay**
+
+## Critical Build Commands
+
+### Primary Build Command
+```bash
+./make_and_restart_relay.sh
+```
+**Never use `make` directly.** The project requires the custom restart script which:
+- Handles database preservation/cleanup based on flags
+- Manages architecture-specific binary detection (x86/ARM64)
+- Performs automatic process cleanup and port management
+- Starts relay in background with proper logging
+
+### Architecture-Specific Binary Outputs
+- **x86_64**: `./build/c_relay_x86`
+- **ARM64**: `./build/c_relay_arm64`
+- **Other**: `./build/c_relay_$(ARCH)`
+
+### Database File Naming Convention
+- **Format**: `<relay_pubkey>.db` (NOT `.nrdb` as shown in docs)
+- **Location**: Created in `build/` directory during execution
+- **Cleanup**: Use `--preserve-database` flag to retain between builds
+
+## Critical Integration Issues
+
+### Event-Based Configuration System
+- **No traditional config files** - all configuration stored in config table
+- Admin private key shown **only once** on first startup
+- Configuration changes require cryptographically signed events
+- Database path determined by generated relay pubkey
+
+### First-Time Startup Sequence
+1. Relay generates admin keypair and relay keypair
+2. Creates database file with relay pubkey as filename
+3. Stores default configuration in config table
+4. **CRITICAL**: Admin private key displayed once and never stored on disk
+
+### Port Management
+- Default port 8888 with automatic fallback (8889, 8890, etc.)
+- Script performs port availability checking before libwebsockets binding
+- Process cleanup includes force-killing processes on port 8888
+
+### Database Schema Dependencies
+- Uses embedded SQL schema (`sql_schema.h`)
+- Schema version 4 with JSON tag storage
+- **Critical**: Event expiration filtering done at application level, not SQL level
+
+### Admin API Event Structure
+```json
+{
+  "kind": 23456,
+  "content": "base64_nip44_encrypted_command_array",
+  "tags": [
+    ["p", "<relay_pubkey>"]
+  ]
+}
+```
+
+**Configuration Commands** (encrypted in content):
+- `["relay_description", "My Relay"]`
+- `["max_subscriptions_per_client", "25"]`
+- `["pow_min_difficulty", "16"]`
+
+**Auth Rule Commands** (encrypted in content):
+- `["blacklist", "pubkey", "hex_pubkey_value"]`
+- `["whitelist", "pubkey", "hex_pubkey_value"]`
+
+**Query Commands** (encrypted in content):
+- `["auth_query", "all"]`
+- `["system_command", "system_status"]`
+
+### Process Management
+```bash
+# Kill existing relay processes
+pkill -f "c_relay_"
+
+# Check running processes
+ps aux | grep c_relay_
+
+# Force kill port binding
+fuser -k 8888/tcp
+```
+
+### Cross-Compilation Specifics
+- ARM64 requires explicit dependency installation: `make install-arm64-deps`
+- Uses `aarch64-linux-gnu-gcc` with specific library paths
+- PKG_CONFIG_PATH must be set for ARM64: `/usr/lib/aarch64-linux-gnu/pkgconfig`
+
+### Testing Integration
+- Tests expect relay running on default port
+- Use `tests/quick_error_tests.sh` for validation
+- Event configuration tests: `tests/event_config_tests.sh`
+
+### SystemD Integration Considerations
+- Service runs as `c-relay` user in `/opt/c-relay`
+- Database files created in WorkingDirectory automatically
+- No environment variables needed (event-based config)
+- Resource limits: 65536 file descriptors, 4096 processes
+
+### Development vs Production Differences
+- Development: `make_and_restart_relay.sh` (default database cleanup)
+- Production: `make_and_restart_relay.sh --preserve-database`
+- Debug build requires manual gdb attachment to architecture-specific binary
+
+### Critical File Dependencies
+- `nostr_core_lib/` submodule must be initialized and built first
+- Version header auto-generated from git tags: `src/version.h`
+- Schema embedded in binary from `src/sql_schema.h`
+
+### WebSocket Protocol Specifics
+- Supports both WebSocket (Nostr protocol) and HTTP (NIP-11)
+- NIP-11 requires `Accept: application/nostr+json` header
+- CORS headers automatically added for NIP-11 compliance
+
+### Memory Management Notes
+- Persistent subscription system with thread-safe global manager
+- Per-session subscription limits enforced
+- Event filtering done at C level, not SQL level for NIP-40 expiration
+
+### Configuration Override Behavior
+- CLI port override only affects first-time startup
+- After database creation, all config comes from events
+- Database path cannot be changed after initialization
+
+## Non-Obvious Pitfalls
+
+1. **Database Lock Issues**: Script handles SQLite locking by killing existing processes first
+2. **Port Race Conditions**: Pre-check + libwebsockets binding can still fail due to timing
+3. **Key Loss**: Admin private key loss requires complete database deletion and restart
+4. **Architecture Detection**: Build system auto-detects but cross-compilation requires manual setup
+5. **Event Storage**: Ephemeral events (kind 20000-29999) accepted but not stored
+6. **Signature Validation**: All events validated with `nostr_verify_event_signature()` from nostr_core_lib
+
+## Quick Debugging Commands
+```bash
+# Check relay status
+ps aux | grep c_relay_ && netstat -tln | grep 8888
+
+# View logs
+tail -f relay.log
+
+# Test WebSocket connection
+wscat -c ws://localhost:8888
+
+# Test NIP-11 endpoint
+curl -H "Accept: application/nostr+json" http://localhost:8888
+
+# Find database files
+find . -name "*.db" -type f

+## Web Admin Interface
+
+C-Relay includes a **built-in web-based administration interface** accessible at `http://localhost:8888/api/`. The interface provides:
+
+- **Real-time Configuration Management**: View and edit all relay settings through a web UI
+- **Database Statistics Dashboard**: Monitor event counts, storage usage, and performance metrics
+- **Auth Rules Management**: Configure whitelist/blacklist rules for pubkeys
+- **NIP-42 Authentication**: Secure access using your Nostr identity
+- **Event-Based Updates**: All changes are applied as cryptographically signed Nostr events
+
+The web interface serves embedded static files with no external dependencies and includes proper CORS headers for browser compatibility.
+
+## Administrator API
+
+C-Relay uses an innovative **event-based administration system** where all configuration and management commands are sent as signed Nostr events using the admin private key generated during first startup. All admin commands use **NIP-44 encrypted command arrays** for security and compatibility.
+
+### Authentication
+
+All admin commands require signing with the admin private key displayed during first-time startup. **Save this key securely** - it cannot be recovered and is needed for all administrative operations.
+
+### Event Structure
+
+All admin commands use the same unified event structure with NIP-44 encrypted content:
+
+**Admin Command Event:**
+```json
+{
+  "id": "event_id",
+  "pubkey": "admin_public_key",
+  "created_at": 1234567890,
+  "kind": 23456,
+  "content": "AqHBUgcM7dXFYLQuDVzGwMST1G8jtWYyVvYxXhVGEu4nAb4LVw...",
+  "tags": [
+    ["p", "relay_public_key"]
+  ],
+  "sig": "event_signature"
+}
+```
+
+The `content` field contains a NIP-44 encrypted JSON array representing the command.
+
+**Admin Response Event:**
+```json
+["EVENT", "temp_sub_id", {
+  "id": "response_event_id",
+  "pubkey": "relay_public_key",
+  "created_at": 1234567890,
+  "kind": 23457,
+  "content": "BpKCVhfN8eYtRmPqSvWxZnMkL2gHjUiOp3rTyEwQaS5dFg...",
+  "tags": [

+
+### Dynamic Configuration Updates
+
+C-Relay supports **dynamic configuration updates** without requiring a restart for most settings. Configuration parameters are categorized as either **dynamic** (can be updated immediately) or **restart-required** (require relay restart to take effect).
+
+**Dynamic Configuration Parameters (No Restart Required):**
+- All relay information (NIP-11) settings: `relay_name`, `relay_description`, `relay_contact`, `relay_software`, `relay_version`, `supported_nips`, `language_tags`, `relay_countries`, `posting_policy`, `payments_url`
+- Authentication settings: `auth_enabled`, `nip42_auth_required`, `nip42_auth_required_kinds`, `nip42_challenge_timeout`
+- Subscription limits: `max_subscriptions_per_client`, `max_total_subscriptions`
+- Event validation limits: `max_event_tags`, `max_content_length`, `max_message_length`
+- Proof of Work settings: `pow_min_difficulty`, `pow_mode`
+- Event expiration settings: `nip40_expiration_enabled`, `nip40_expiration_strict`, `nip40_expiration_filter`, `nip40_expiration_grace_period`
+
+**Restart-Required Configuration Parameters:**
+- Connection settings: `max_connections`, `relay_port`
+- Database and core system settings
+
+When updating configuration, the admin API response will indicate whether a restart is required for each parameter. Dynamic updates take effect immediately and are reflected in NIP-11 relay information documents without restart.
+
+### Response Format
+
+All admin commands return **signed EVENT responses** via WebSocket following standard Nostr protocol. Responses use JSON content with structured data.

+
+##  Direct Messaging Admin System
+
+In addition to the above admin API, c-relay allows the administrator to direct message the relay to get information or control some settings. As long as the administrator is signed in with any nostr client that allows sending nip-17 direct messages (DMs), they can control the relay.
+
+The is possible because the relay is a full nostr citizen with it's own private and public key.
+
+
+
+**Available DM commands**
+
+The intent is not to be strict in the formatting of the DM. So for example if the relay receives any DM from the administrator with the words "stats" or "statistics" in it, it will respond to the administrator with a reply DM with the current relay statistics.
+
+- `stats`|`statistics`: Relay statistics
+- `config`|`configuration`: Relay configuration

-# C Nostr Relay Database
-
-This directory contains the SQLite database schema and initialization scripts for the C Nostr Relay implementation.
-
-## Files
-
-- **`schema.sql`** - Complete database schema based on nostr-rs-relay v18
-- **`init.sh`** - Database initialization script
-- **`c_nostr_relay.db`** - SQLite database file (created after running init.sh)
-
-## Quick Start
-
-1. **Initialize the database:**
-   ```bash
-   cd db
-   ./init.sh
-   ```
-
-2. **Force reinitialize (removes existing database):**
-   ```bash
-   ./init.sh --force
-   ```
-
-3. **Initialize with optimization and info:**
-   ```bash
-   ./init.sh --info --optimize
-   ```
-
-## Database Schema
-
-The schema is fully compatible with the Nostr protocol and includes:
-
-### Core Tables
-
-- **`event`** - Main event storage with all Nostr event data
-- **`tag`** - Denormalized tag index for efficient queries
-- **`user_verification`** - NIP-05 verification tracking
-- **`account`** - User account management (optional)
-- **`invoice`** - Lightning payment tracking (optional)
-
-### Key Features
-
-- ✅ **NIP-01 compliant** - Full basic protocol support
-- ✅ **Replaceable events** - Supports kinds 0, 3, 10000-19999
-- ✅ **Parameterized replaceable** - Supports kinds 30000-39999 with `d` tags
-- ✅ **Event deletion** - NIP-09 soft deletion with `hidden` column
-- ✅ **Event expiration** - NIP-40 automatic cleanup
-- ✅ **Authentication** - NIP-42 client authentication
-- ✅ **NIP-05 verification** - Domain-based identity verification
-- ✅ **Performance optimized** - Comprehensive indexing strategy
-
-### Schema Version
-
-Current version: **v18** (compatible with nostr-rs-relay v18)
-
-## Database Structure
-
-### Event Storage
-```sql
-CREATE TABLE event (
-    id INTEGER PRIMARY KEY,
-    event_hash BLOB NOT NULL,        -- 32-byte SHA256 hash
-    first_seen INTEGER NOT NULL,     -- relay receive timestamp
-    created_at INTEGER NOT NULL,     -- event creation timestamp
-    expires_at INTEGER,              -- NIP-40 expiration
-    author BLOB NOT NULL,            -- 32-byte pubkey
-    delegated_by BLOB,               -- NIP-26 delegator
-    kind INTEGER NOT NULL,           -- event kind
-    hidden INTEGER DEFAULT FALSE,   -- soft deletion flag
-    content TEXT NOT NULL            -- complete JSON event
-);
-```
-
-### Tag Indexing
-```sql
-CREATE TABLE tag (
-    id INTEGER PRIMARY KEY,
-    event_id INTEGER NOT NULL,
-    name TEXT,                       -- tag name ("e", "p", etc.)
-    value TEXT,                      -- tag value
-    created_at INTEGER NOT NULL,     -- denormalized for performance
-    kind INTEGER NOT NULL            -- denormalized for performance
-);
-```
-
-## Performance Features
-
-### Optimized Indexes
-- **Hash-based lookups** - `event_hash_index` for O(1) event retrieval
-- **Author queries** - `author_index`, `author_created_at_index`
-- **Kind filtering** - `kind_index`, `kind_created_at_index`
-- **Tag searching** - `tag_covering_index` for efficient tag queries
-- **Composite queries** - Multi-column indexes for complex filters
-
-### Query Optimization
-- **Denormalized tags** - Includes `kind` and `created_at` in tag table
-- **Binary storage** - BLOBs for hex data (pubkeys, hashes)
-- **WAL mode** - Write-Ahead Logging for concurrent access
-- **Automatic cleanup** - Triggers for data integrity
-
-## Usage Examples
-
-### Basic Operations
-
-1. **Insert an event:**
-   ```sql
-   INSERT INTO event (event_hash, first_seen, created_at, author, kind, content)
-   VALUES (?, ?, ?, ?, ?, ?);
-   ```
-
-2. **Query by author:**
-   ```sql
-   SELECT content FROM event 
-   WHERE author = ? AND hidden != TRUE
-   ORDER BY created_at DESC;
-   ```
-
-3. **Filter by tags:**
-   ```sql
-   SELECT e.content FROM event e
-   JOIN tag t ON e.id = t.event_id
-   WHERE t.name = 'p' AND t.value = ? AND e.hidden != TRUE;
-   ```
-
-### Advanced Queries
-
-1. **Get replaceable event (latest only):**
-   ```sql
-   SELECT content FROM event
-   WHERE author = ? AND kind = ? AND hidden != TRUE
-   ORDER BY created_at DESC LIMIT 1;
-   ```
-
-2. **Tag-based filtering (NIP-01 filters):**
-   ```sql
-   SELECT e.content FROM event e
-   WHERE e.id IN (
-     SELECT t.event_id FROM tag t
-     WHERE t.name = ? AND t.value IN (?, ?, ?)
-   ) AND e.hidden != TRUE;
-   ```
-
-## Maintenance
-
-### Regular Operations
-
-1. **Check database integrity:**
-   ```bash
-   sqlite3 c_nostr_relay.db "PRAGMA integrity_check;"
-   ```
-
-2. **Optimize database:**
-   ```bash
-   sqlite3 c_nostr_relay.db "PRAGMA optimize; VACUUM; ANALYZE;"
-   ```
-
-3. **Clean expired events:**
-   ```sql
-   DELETE FROM event WHERE expires_at <= strftime('%s', 'now');
-   ```
-
-### Monitoring
-
-1. **Database size:**
-   ```bash
-   ls -lh c_nostr_relay.db
-   ```
-
-2. **Table statistics:**
-   ```sql
-   SELECT name, COUNT(*) as count FROM (
-     SELECT 'events' as name FROM event UNION ALL
-     SELECT 'tags' as name FROM tag UNION ALL
-     SELECT 'verifications' as name FROM user_verification
-   ) GROUP BY name;
-   ```
-
-## Migration Support
-
-The schema includes a migration system for future updates:
-
-```sql
-CREATE TABLE schema_info (
-    version INTEGER PRIMARY KEY,
-    applied_at INTEGER NOT NULL,
-    description TEXT
-);
-```
-
-## Security Considerations
-
-1. **Input validation** - Always validate event JSON and signatures
-2. **Rate limiting** - Implement at application level
-3. **Access control** - Use `account` table for permissions
-4. **Backup strategy** - Regular database backups recommended
-
-## Compatibility
-
-- **SQLite version** - Requires SQLite 3.8.0+
-- **nostr-rs-relay** - Schema compatible with v18
-- **NIPs supported** - 01, 02, 05, 09, 10, 11, 26, 40, 42
-- **C libraries** - Compatible with sqlite3 C API
-
-## Troubleshooting
-
-### Common Issues
-
-1. **Database locked error:**
-   - Ensure proper connection closing in your C code
-   - Check for long-running transactions
-
-2. **Performance issues:**
-   - Run `PRAGMA optimize;` regularly
-   - Consider `VACUUM` if database grew significantly
-
-3. **Schema errors:**
-   - Verify SQLite version compatibility
-   - Check foreign key constraints
-
-### Getting Help
-
-- Check the main project README for C implementation details
-- Review nostr-rs-relay documentation for reference implementation
-- Consult Nostr NIPs for protocol specifications

+# NIP-42 Authentication Implementation
+
+## Overview
+
+This relay implements NIP-42 (Authentication of clients to relays) providing granular authentication controls for event submission and subscription operations. The implementation supports both challenge-response authentication and per-connection state management.
+
+## Architecture
+
+### Core Components
+
+1. **Per-Session Authentication State** (`struct per_session_data`)
+   - `authenticated`: Boolean flag indicating authentication status
+   - `authenticated_pubkey[65]`: Hex-encoded public key of authenticated user
+   - `active_challenge[65]`: Current authentication challenge
+   - `challenge_created`: Timestamp when challenge was generated
+   - `challenge_expires`: Challenge expiration timestamp
+   - `nip42_auth_required_events`: Whether auth is required for EVENT submission
+   - `nip42_auth_required_subscriptions`: Whether auth is required for REQ operations
+   - `auth_challenge_sent`: Flag indicating if challenge has been sent
+
+2. **Challenge Management** (via `request_validator.c`)
+   - `nostr_nip42_generate_challenge()`: Generates cryptographically secure challenges
+   - `nostr_nip42_verify_auth_event()`: Validates signed authentication events
+   - Challenge storage and cleanup with expiration handling
+
+3. **WebSocket Protocol Integration**
+   - AUTH message handling in `nostr_relay_callback()`
+   - Challenge generation and transmission
+   - Authentication verification and session state updates
+
+## Configuration Options
+
+### Event-Based Configuration
+
+NIP-42 authentication is configured using kind 33334 configuration events with the following tags:
+
+| Tag | Description | Default | Values |
+|-----|-------------|---------|--------|
+| `nip42_auth_required_events` | Require auth for EVENT submission | `false` | `true`/`false` |
+| `nip42_auth_required_subscriptions` | Require auth for REQ operations | `false` | `true`/`false` |
+
+### Example Configuration Event
+
+```json
+{
+  "kind": 33334,
+  "content": "C Nostr Relay Configuration",
+  "tags": [
+    ["d", "<relay_pubkey>"],
+    ["nip42_auth_required_events", "true"],
+    ["nip42_auth_required_subscriptions", "false"],
+    ["relay_description", "Authenticated Nostr Relay"]
+  ],
+  "created_at": 1640995200,
+  "pubkey": "<admin_pubkey>",
+  "id": "<event_id>",
+  "sig": "<signature>"
+}
+```
+
+## Authentication Flow
+
+### 1. Challenge Generation
+
+When authentication is required and client is not authenticated:
+
+```
+Client -> Relay: ["EVENT", <event>] (unauthenticated)
+Relay -> Client: ["AUTH", <challenge>]
+```
+
+The challenge is a 64-character hex string generated using cryptographically secure random numbers.
+
+### 2. Authentication Response
+
+Client creates and signs an authentication event (kind 22242):
+
+```json
+{
+  "kind": 22242,
+  "content": "",
+  "tags": [
+    ["relay", "ws://relay.example.com"],
+    ["challenge", "<challenge_from_relay>"]
+  ],
+  "created_at": <current_timestamp>,
+  "pubkey": "<client_pubkey>",
+  "id": "<event_id>",
+  "sig": "<signature>"
+}
+```
+
+Client sends this event back to relay:
+
+```
+Client -> Relay: ["AUTH", <signed_auth_event>]
+```
+
+### 3. Verification and Session Update
+
+The relay:
+1. Validates the authentication event signature
+2. Verifies the challenge matches the one sent
+3. Checks challenge expiration (default: 10 minutes)
+4. Updates session state with authenticated public key
+5. Sends confirmation notice
+
+```
+Relay -> Client: ["NOTICE", "NIP-42 authentication successful"]
+```
+
+## Granular Authentication Controls
+
+### Separate Controls for Events vs Subscriptions
+
+The implementation provides separate authentication requirements:
+
+- **Event Submission**: Control whether clients must authenticate to publish events
+- **Subscription Access**: Control whether clients must authenticate to create subscriptions
+
+This allows flexible relay policies:
+- **Public Read, Authenticated Write**: `events=true, subscriptions=false`
+- **Fully Authenticated**: `events=true, subscriptions=true`
+- **Public Access**: `events=false, subscriptions=false` (default)
+- **Authenticated Read Only**: `events=false, subscriptions=true`
+
+### Per-Connection State
+
+Each WebSocket connection maintains its own authentication state:
+- Authentication persists for the lifetime of the connection
+- Challenges expire after 10 minutes
+- Session cleanup on connection close
+
+## Security Features
+
+### Challenge Security
+- 64-character hexadecimal challenges (256 bits of entropy)
+- Cryptographically secure random generation
+- Challenge expiration to prevent replay attacks
+- One-time use challenges
+
+### Event Validation
+- Complete signature verification using secp256k1
+- Event ID validation
+- Challenge-response binding verification
+- Timestamp validation with configurable tolerance
+
+### Session Management
+- Thread-safe per-session state management
+- Automatic cleanup on disconnection
+- Challenge expiration handling
+
+## Client Integration
+
+### Using nak Client
+
+```bash
+# Generate keypair
+PRIVKEY=$(nak key --gen)
+PUBKEY=$(nak key --pub $PRIVKEY)
+
+# Connect and authenticate automatically
+nak event -k 1 --content "Authenticated message" --sec $PRIVKEY --relay ws://localhost:8888
+
+# nak handles NIP-42 authentication automatically when required
+```
+
+### Manual WebSocket Integration
+
+```javascript
+const ws = new WebSocket('ws://localhost:8888');
+
+ws.onmessage = (event) => {
+  const message = JSON.parse(event.data);
+  
+  if (message[0] === 'AUTH') {
+    const challenge = message[1];
+    
+    // Create auth event (kind 22242)
+    const authEvent = {
+      kind: 22242,
+      content: "",
+      tags: [
+        ["relay", "ws://localhost:8888"],
+        ["challenge", challenge]
+      ],
+      created_at: Math.floor(Date.now() / 1000),
+      pubkey: clientPubkey,
+      // ... calculate id and signature
+    };
+    
+    // Send auth response
+    ws.send(JSON.stringify(["AUTH", authEvent]));
+  }
+};
+
+// Send event (may trigger AUTH challenge)
+ws.send(JSON.stringify(["EVENT", myEvent]));
+```
+
+## Administration
+
+### Enabling Authentication
+
+1. **Get Admin Private Key**: Extract from relay startup logs (shown once)
+2. **Create Configuration Event**: Use nak or custom tooling
+3. **Publish Configuration**: Send to relay with admin signature
+
+```bash
+# Enable auth for events only
+nak event -k 33334 \
+  --content "C Nostr Relay Configuration" \
+  --tag "d=$RELAY_PUBKEY" \
+  --tag "nip42_auth_required_events=true" \
+  --tag "nip42_auth_required_subscriptions=false" \
+  --sec $ADMIN_PRIVKEY \
+  --relay ws://localhost:8888
+```
+
+### Monitoring Authentication
+
+- Check relay logs for authentication events
+- Monitor `NOTICE` messages for auth status
+- Use `get_settings.sh` script to view current configuration
+
+```bash
+./get_settings.sh
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Challenge Expiration**
+   - Default: 10 minutes
+   - Client must respond within expiration window
+   - Generate new challenge for expired attempts
+
+2. **Signature Verification Failures**
+   - Verify event structure matches NIP-42 specification
+   - Check challenge value matches exactly
+   - Ensure proper secp256k1 signature generation
+
+3. **Configuration Not Applied**
+   - Verify admin private key is correct
+   - Check configuration event signature
+   - Ensure relay pubkey in 'd' tag matches relay
+
+### Debug Commands
+
+```bash
+# Check supported NIPs
+curl -H "Accept: application/nostr+json" http://localhost:8888 | jq .supported_nips
+
+# View current configuration
+nak req -k 33334 ws://localhost:8888 | jq .
+
+# Test authentication flow
+./tests/42_nip_test.sh
+```
+
+## Performance Considerations
+
+- Challenge generation: ~1ms overhead per unauthenticated connection
+- Authentication verification: ~2-5ms per auth event
+- Memory overhead: ~200 bytes per connection for auth state
+- Database impact: Configuration events cached, minimal query overhead
+
+## Integration with Other NIPs
+
+### NIP-01 (Basic Protocol)
+- AUTH messages integrated into standard WebSocket flow
+- Compatible with existing EVENT/REQ/CLOSE message handling
+
+### NIP-11 (Relay Information)
+- NIP-42 advertised in `supported_nips` array
+- Authentication requirements reflected in relay metadata
+
+### NIP-20 (Command Results)
+- OK responses include authentication-related error messages
+- NOTICE messages provide authentication status updates
+
+## Future Extensions
+
+### Potential Enhancements
+- Role-based authentication (admin, user, read-only)
+- Time-based access controls
+- Rate limiting based on authentication status
+- Integration with external authentication providers
+
+### Configuration Extensions
+- Per-kind authentication requirements
+- Whitelist/blacklist integration
+- Custom challenge expiration times
+- Authentication logging and metrics

+# C-Relay Administrator API Implementation Plan
+
+## Problem Analysis
+
+### Current Issues Identified:
+
+1. **Schema Mismatch**: Storage system (config.c) vs Validation system (request_validator.c) use different column names and values
+2. **Missing API Endpoint**: No way to clear auth_rules table for testing
+3. **Configuration Gap**: Auth rules enforcement may not be properly enabled
+4. **Documentation Gap**: Admin API commands not documented
+
+### Root Cause: Auth Rules Schema Inconsistency
+
+**Current Schema (sql_schema.h lines 140-150):**
+```sql
+CREATE TABLE auth_rules (
+    rule_type TEXT CHECK (rule_type IN ('whitelist', 'blacklist')),
+    pattern_type TEXT CHECK (pattern_type IN ('pubkey', 'hash')),  
+    pattern_value TEXT,
+    action TEXT CHECK (action IN ('allow', 'deny')),
+    active INTEGER DEFAULT 1
+);
+```
+
+**Storage Implementation (config.c):**
+- Stores: `rule_type='blacklist'`, `pattern_type='pubkey'`, `pattern_value='hex'`, `action='allow'`
+
+**Validation Implementation (request_validator.c):**
+- Queries: `rule_type='pubkey_blacklist'`, `rule_target='hex'`, `operation='event'`, `enabled=1`
+
+**MISMATCH**: Validator looks for non-existent columns and wrong rule_type values!
+
+## Proposed Solution Architecture
+
+### Phase 1: API Documentation & Standardization
+
+#### Admin API Commands (via WebSocket with admin private key)
+
+**Kind 23456: Unified Admin API (Ephemeral)**
+- Configuration management: Update relay settings, limits, authentication policies
+- Auth rules: Add/remove/query whitelist/blacklist rules
+- System commands: clear rules, status, cache management
+- **Unified Format**: All commands use NIP-44 encrypted content with `["p", "relay_pubkey"]` tags
+- **Command Types**:
+  - Configuration: `["config_key", "config_value"]`
+  - Auth rules: `["rule_type", "pattern_type", "pattern_value"]`
+  - Queries: `["auth_query", "filter"]` or `["system_command", "command_name"]`
+- **Security**: All admin commands use NIP-44 encryption for privacy and security
+
+#### Configuration Commands (using Kind 23456)
+
+1. **Update Configuration**:
+   ```json
+   {
+     "kind": 23456,
+     "content": "base64_nip44_encrypted_command_array",
+     "tags": [["p", "relay_pubkey"]]
+   }
+   ```
+   *Encrypted content contains:* `["relay_description", "My Relay"]`
+
+2. **Query System Status**:
+   ```json
+   {
+     "kind": 23456,
+     "content": "base64_nip44_encrypted_command_array",
+     "tags": [["p", "relay_pubkey"]]
+   }
+   ```
+   *Encrypted content contains:* `["system_command", "system_status"]`
+
+#### Auth Rules and System Commands (using Kind 23456)
+
+1. **Clear All Auth Rules**:
+   ```json
+   {
+     "kind": 23456,
+     "content": "base64_nip44_encrypted_command_array",
+     "tags": [["p", "relay_pubkey"]]
+   }
+   ```
+   *Encrypted content contains:* `["system_command", "clear_all_auth_rules"]`
+
+2. **Query All Auth Rules**:
+   ```json
+   {
+     "kind": 23456,
+     "content": "base64_nip44_encrypted_command_array",
+     "tags": [["p", "relay_pubkey"]]
+   }
+   ```
+   *Encrypted content contains:* `["auth_query", "all"]`
+
+3. **Add Blacklist Rule**:
+   ```json
+   {
+     "kind": 23456,
+     "content": "base64_nip44_encrypted_command_array",
+     "tags": [["p", "relay_pubkey"]]
+   }
+   ```
+   *Encrypted content contains:* `["blacklist", "pubkey", "deadbeef1234abcd..."]`
+
+### Phase 2: Auth Rules Schema Alignment
+
+#### Option A: Fix Validator to Match Schema (RECOMMENDED)
+
+**Update request_validator.c:**
+```sql
+-- OLD (broken):
+WHERE rule_type = 'pubkey_blacklist' AND rule_target = ? AND operation = ? AND enabled = 1
+
+-- NEW (correct):
+WHERE rule_type = 'blacklist' AND pattern_type = 'pubkey' AND pattern_value = ? AND active = 1
+```
+
+**Benefits:**
+- Matches actual database schema
+- Simpler rule_type values ('blacklist' vs 'pubkey_blacklist')  
+- Uses existing columns (pattern_value vs rule_target)
+- Consistent with storage implementation
+
+#### Option B: Update Schema to Match Validator (NOT RECOMMENDED)
+
+Would require changing schema, migration scripts, and storage logic.
+
+### Phase 3: Implementation Priority
+
+#### High Priority (Critical for blacklist functionality):
+1. Fix request_validator.c schema mismatch
+2. Ensure auth_required configuration is enabled
+3. Update tests to use unified ephemeral event kind (23456)
+4. Test blacklist enforcement
+
+#### Medium Priority (Enhanced Admin Features):
+1. **Implement NIP-44 Encryption Support**:
+   - Detect NIP-44 encrypted content for Kind 23456 events
+   - Parse `encrypted_tags` field from content JSON
+   - Decrypt using admin privkey and relay pubkey
+   - Process decrypted tags as normal commands
+2. Add clear_all_auth_rules system command
+3. Add auth rule query functionality (both standard and encrypted modes)
+4. Add configuration discovery (list available config keys)
+5. Enhanced error reporting in admin API
+6. Conflict resolution (same pubkey in whitelist + blacklist)
+
+#### Security Priority (NIP-44 Implementation):
+1. **Encryption Detection Logic**: Check for empty tags + encrypted_tags field
+2. **Key Pair Management**: Use admin private key + relay public key for NIP-44
+3. **Backward Compatibility**: Support both standard and encrypted modes
+4. **Error Handling**: Graceful fallback if decryption fails
+5. **Performance**: Cache decrypted results to avoid repeated decryption
+
+#### Low Priority (Documentation & Polish):
+1. Complete README.md API documentation
+2. Example usage scripts
+3. Admin client tools
+
+### Phase 4: Expected API Structure
+
+#### README.md Documentation Format:
+
+```markdown
+# C-Relay Administrator API
+
+## Authentication
+All admin commands require signing with the admin private key generated during first startup.
+
+## Unified Admin API (Kind 23456 - Ephemeral)
+Update relay configuration parameters or query available settings.
+
+**Configuration Update Event:**
+```json
+{
+  "kind": 23456,
+  "content": "base64_nip44_encrypted_command_array",
+  "tags": [["p", "relay_pubkey"]]
+}
+```
+*Encrypted content contains:* `["relay_description", "My Relay Description"]`
+
+**Auth Rules Management:**
+
+**Add Rule Event:**

+  ]
+}
+```
+
+**Query Whitelist Rules Only:**
+```json
+{
+  "kind": 23456,
+  "content": "{\"query\":\"list_auth_rules\",\"description\":\"Get whitelist\"}",
+  "tags": [
+    ["auth_query", "whitelist"]
+  ]
+}
+```
+
+**Check Specific Pattern:**

+  "content": "{\"query\":\"check_pattern\",\"description\":\"Check if pattern exists\"}",
+  "tags": [
+    ["auth_query", "pattern", "deadbeef1234..."]
+  ]
+}
+```
+
+## System Management (Kind 23456 - Ephemeral)
+System administration commands using the same kind as auth rules.
+
+**Clear All Auth Rules:**
+```json
+{
+  "kind": 23456,
+  "content": "{\"action\":\"clear_all\",\"description\":\"Clear all auth rules\"}",
+  "tags": [
+    ["system_command", "clear_all_auth_rules"]

+  "content": "{\"action\":\"system_status\",\"description\":\"Get system status\"}",
+  "tags": [
+    ["system_command", "system_status"]
+  ]
+}
+```
+
+## Response Format
+All admin commands return JSON responses via WebSocket:
+
+**Success Response:**
+```json
+["OK", "event_id", true, "success_message"]
+```
+
+**Error Response:**  
+```json
+["OK", "event_id", false, "error_message"]
+```
+
+## Configuration Keys
+- `relay_description`: Relay description text
+- `relay_contact`: Contact information  
+- `auth_enabled`: Enable authentication system
+- `max_connections`: Maximum concurrent connections
+- `pow_min_difficulty`: Minimum proof-of-work difficulty
+- ... (full list of config keys)
+
+## Examples
+
+### Enable Authentication & Add Blacklist
+```bash
+# 1. Enable auth system
+nak event -k 23456 --content "base64_nip44_encrypted_command" \
+  -t "auth_enabled=true" \
+  --sec $ADMIN_PRIVKEY | nak event ws://localhost:8888
+
+# 2. Add user to blacklist
+nak event -k 23456 --content '{"action":"add","description":"Spam user"}' \
+  -t "blacklist=pubkey;$SPAM_USER_PUBKEY" \
+  --sec $ADMIN_PRIVKEY | nak event ws://localhost:8888
+
+# 3. Query all auth rules
+nak event -k 23456 --content '{"query":"list_auth_rules","description":"Get all rules"}' \
+  -t "auth_query=all" \
+  --sec $ADMIN_PRIVKEY | nak event ws://localhost:8888
+
+# 4. Clear all rules for testing
+nak event -k 23456 --content '{"action":"clear_all","description":"Clear all rules"}' \
+  -t "system_command=clear_all_auth_rules" \
+  --sec $ADMIN_PRIVKEY | nak event ws://localhost:8888
+```
+
+## Expected Response Formats
+
+### Configuration Query Response
+```json
+["EVENT", "subscription_id", {
+  "kind": 23457,
+  "content": "base64_nip44_encrypted_response",
+  "tags": [["p", "admin_pubkey"]]
+}]
+```
+
+### Current Config Response
+```json
+["EVENT", "subscription_id", {
+  "kind": 23457,
+  "content": "base64_nip44_encrypted_response",
+  "tags": [["p", "admin_pubkey"]]
+}]
+```
+
+### Auth Rules Query Response
+```json
+["EVENT", "subscription_id", {
+  "kind": 23456,
+  "content": "{\"auth_rules\": [{\"rule_type\": \"blacklist\", \"pattern_type\": \"pubkey\", \"pattern_value\": \"deadbeef...\"}, {\"rule_type\": \"whitelist\", \"pattern_type\": \"pubkey\", \"pattern_value\": \"cafebabe...\"}]}",
+  "tags": [["response_type", "auth_rules_list"], ["query_type", "all"]]
+}]
+```
+
+### Pattern Check Response
+```json
+["EVENT", "subscription_id", {
+  "kind": 23456,
+  "content": "{\"pattern_exists\": true, \"rule_type\": \"blacklist\", \"pattern_value\": \"deadbeef...\"}",
+  "tags": [["response_type", "pattern_check"], ["pattern", "deadbeef..."]]
+}]
+```
+
+## Implementation Steps
+
+1. **Document API** (this file) ✅
+2. **Update to ephemeral event kinds** ✅
+3. **Fix request_validator.c** schema mismatch
+4. **Update tests** to use unified Kind 23456

+4. Test all admin API commands end-to-end
+5. Update integration tests
+
+This plan addresses the immediate blacklist issue while establishing a comprehensive admin API framework for future expansion.
+
+## NIP-44 Encryption Implementation Details
+
+### Server-Side Detection Logic
+```c
+// In admin event processing function
+bool is_encrypted_command(struct nostr_event *event) {
+    // Check if Kind 23456 with NIP-44 encrypted content
+    if (event->kind == 23456 &&
+        event->tags_count == 0) {
+        return true;
+    }
+    return false;
+}
+
+cJSON *decrypt_admin_tags(struct nostr_event *event) {
+    cJSON *content_json = cJSON_Parse(event->content);
+    if (!content_json) return NULL;
+    
+    cJSON *encrypted_tags = cJSON_GetObjectItem(content_json, "encrypted_tags");
+    if (!encrypted_tags) {
+        cJSON_Delete(content_json);
+        return NULL;
+    }
+    
+    // Decrypt using NIP-44 with admin pubkey and relay privkey
+    char *decrypted = nip44_decrypt(
+        cJSON_GetStringValue(encrypted_tags),
+        admin_pubkey,           // Shared secret with admin
+        relay_private_key       // Our private key
+    );
+    
+    cJSON *decrypted_tags = cJSON_Parse(decrypted);
+    free(decrypted);
+    cJSON_Delete(content_json);
+    
+    return decrypted_tags; // Returns tag array: [["key1", "val1"], ["key2", "val2"]]
+}
+```
+
+### Admin Event Processing Flow
+1. **Receive Event**: Kind 23456 with admin signature
+2. **Check Mode**: Empty tags = encrypted, populated tags = standard
+3. **Decrypt if Needed**: Extract and decrypt `encrypted_tags` from content
+4. **Process Commands**: Use decrypted/standard tags for command processing
+5. **Execute**: Same logic for both modes after tag extraction
+6. **Respond**: Standard response format (optionally encrypt response)
+
+### Security Benefits
+- **Command Privacy**: Admin operations invisible in event tags
+- **Replay Protection**: NIP-44 includes timestamp/randomness
+- **Key Management**: Uses existing admin/relay key pair
+- **Backward Compatible**: Standard mode still works
+- **Performance**: Only decrypt when needed (empty tags detection)
+
+### NIP-44 Library Integration
+The relay will need to integrate a NIP-44 encryption/decryption library:
+
+```c
+// Required NIP-44 functions
+char* nip44_encrypt(const char* plaintext, const char* sender_privkey, const char* recipient_pubkey);
+char* nip44_decrypt(const char* ciphertext, const char* recipient_privkey, const char* sender_pubkey);
+```
+
+### Implementation Priority (Updated)
+
+#### Phase 1: Core Infrastructure (Complete)
+- [x] Event-based admin authentication system
+- [x] Kind 23456 (Unified Admin API) processing
+- [x] Basic configuration parameter updates
+- [x] Auth rule add/remove/clear functionality
+- [x] Updated to ephemeral event kinds
+- [x] Designed NIP-44 encryption support
+
+#### Phase 2: NIP-44 Encryption Support (Next Priority)
+- [ ] **Add NIP-44 library dependency** to project
+- [ ] **Implement encryption detection logic** (`is_encrypted_command()`)
+- [ ] **Add decrypt_admin_tags() function** with NIP-44 support
+- [ ] **Update admin command processing** to handle both modes
+- [ ] **Test encrypted admin commands** end-to-end
+
+#### Phase 3: Enhanced Features
+- [ ] **Auth rule query functionality** (both standard and encrypted modes)
+- [ ] **Configuration discovery API** (list available config keys)
+- [ ] **Enhanced error messages** with encryption status
+- [ ] **Performance optimization** (caching, async decrypt)
+
+#### Phase 4: Schema Fixes (Critical)
+- [ ] **Fix request_validator.c** schema mismatch
+- [ ] **Enable blacklist enforcement** with encrypted commands
+- [ ] **Update tests** to use both standard and encrypted modes
+
+This enhanced admin API provides enterprise-grade security while maintaining ease of use for basic operations.

-# Database Configuration Schema Design
-
-## Overview
-This document outlines the database configuration schema additions for the C Nostr Relay startup config file system. The design follows the Ginxsom admin system approach with signed Nostr events and database storage.
-
-## Schema Version Update
-- Current Version: 2
-- Target Version: 3
-- Update: Add server configuration management tables
-
-## Core Configuration Tables
-
-### 1. `server_config` Table
-
-```sql
--- Server configuration table - core configuration storage
-CREATE TABLE server_config (
-    key TEXT PRIMARY KEY,                    -- Configuration key (unique identifier)
-    value TEXT NOT NULL,                     -- Configuration value (stored as string)
-    description TEXT,                        -- Human-readable description
-    config_type TEXT DEFAULT 'user' CHECK (config_type IN ('system', 'user', 'runtime')),
-    data_type TEXT DEFAULT 'string' CHECK (data_type IN ('string', 'integer', 'boolean', 'json')),
-    validation_rules TEXT,                   -- JSON validation rules (optional)
-    is_sensitive INTEGER DEFAULT 0,          -- 1 if value should be masked in logs
-    requires_restart INTEGER DEFAULT 0,      -- 1 if change requires server restart
-    created_at INTEGER NOT NULL DEFAULT (strftime('%s', 'now')),
-    updated_at INTEGER NOT NULL DEFAULT (strftime('%s', 'now'))
-);
-```
-
-**Configuration Types:**
-- `system`: Core system settings (admin keys, security)
-- `user`: User-configurable settings (relay info, features)
-- `runtime`: Dynamic runtime values (statistics, cache)
-
-**Data Types:**
-- `string`: Text values
-- `integer`: Numeric values
-- `boolean`: True/false values (stored as "true"/"false")
-- `json`: JSON object/array values
-
-### 2. `config_history` Table
-
-```sql
--- Configuration change history table
-CREATE TABLE config_history (
-    id INTEGER PRIMARY KEY AUTOINCREMENT,
-    config_key TEXT NOT NULL,               -- Key that was changed
-    old_value TEXT,                         -- Previous value (NULL for new keys)
-    new_value TEXT NOT NULL,                -- New value
-    changed_by TEXT DEFAULT 'system',       -- Who made the change (system/admin/user)
-    change_reason TEXT,                     -- Optional reason for change
-    changed_at INTEGER NOT NULL DEFAULT (strftime('%s', 'now')),
-    FOREIGN KEY (config_key) REFERENCES server_config(key)
-);
-```
-
-### 3. `config_validation_log` Table
-
-```sql
--- Configuration validation errors log
-CREATE TABLE config_validation_log (
-    id INTEGER PRIMARY KEY AUTOINCREMENT,
-    config_key TEXT NOT NULL,
-    attempted_value TEXT,
-    validation_error TEXT NOT NULL,
-    error_source TEXT DEFAULT 'validation',  -- validation/parsing/constraint
-    attempted_at INTEGER NOT NULL DEFAULT (strftime('%s', 'now'))
-);
-```
-
-### 4. Configuration File Cache Table
-
-```sql
--- Cache for file-based configuration events
-CREATE TABLE config_file_cache (
-    file_path TEXT PRIMARY KEY,             -- Full path to config file
-    file_hash TEXT NOT NULL,                -- SHA256 hash of file content
-    event_id TEXT,                          -- Nostr event ID from file
-    event_pubkey TEXT,                      -- Admin pubkey that signed event
-    loaded_at INTEGER NOT NULL DEFAULT (strftime('%s', 'now')),
-    validation_status TEXT CHECK (validation_status IN ('valid', 'invalid', 'unverified')),
-    validation_error TEXT                   -- Error details if invalid
-);
-```
-
-## Indexes and Performance
-
-```sql
--- Performance indexes for configuration tables
-CREATE INDEX idx_server_config_type ON server_config(config_type);
-CREATE INDEX idx_server_config_updated ON server_config(updated_at DESC);
-CREATE INDEX idx_config_history_key ON config_history(config_key);

-CREATE INDEX idx_config_validation_key ON config_validation_log(config_key);
-CREATE INDEX idx_config_validation_time ON config_validation_log(attempted_at DESC);
-```

-
-```sql
--- Trigger to update timestamp on configuration changes
-CREATE TRIGGER update_config_timestamp
-    AFTER UPDATE ON server_config
-BEGIN
-    UPDATE server_config SET updated_at = strftime('%s', 'now') WHERE key = NEW.key;
-END;
-```
-
-### Configuration History Trigger
-
-```sql
--- Trigger to log configuration changes to history
-CREATE TRIGGER log_config_changes
-    AFTER UPDATE ON server_config
-    WHEN OLD.value != NEW.value
-BEGIN

-  "required": true
-}
-```
-
-```json
-{
-  "type": "string",
-  "pattern": "^[0-9a-fA-F]{64}$",

-}
-```
-
-```json
-{
-  "type": "boolean",
-  "required": true
-}

-
-## Migration Strategy
-
-1. **Phase 1**: Add configuration tables to existing schema
-2. **Phase 2**: Populate with current hardcoded values
-3. **Phase 3**: Update application code to read from database
-4. **Phase 4**: Add file-based configuration loading
-5. **Phase 5**: Remove hardcoded defaults and environment variable fallbacks

+
+## Overview
+
+The C Nostr Relay uses a revolutionary **event-based configuration system** where all settings are stored as kind 33334 Nostr events in the database. This provides several advantages:
+
+### Benefits
+- **Real-time updates**: Configuration changes applied instantly without restart
+- **Cryptographic security**: All changes must be cryptographically signed by admin
+- **Audit trail**: Complete history of all configuration changes
+- **Version control**: Each configuration change is timestamped and signed
+- **Zero files**: No configuration files to manage, backup, or version control
+
+### How It Works
+1. **Admin keypair**: Generated on first startup, used to sign configuration events
+2. **Configuration events**: Kind 33334 Nostr events with relay settings in tags
+3. **Real-time processing**: New configuration events processed via WebSocket
+4. **Immediate application**: Changes applied to running system without restart
+
+## Configuration Events
+
+### Event Structure
+
+Configuration events follow the standard Nostr event format with kind 33334:
+
+```json
+{
+  "id": "event_id_computed_from_content",
+  "kind": 33334,
+  "pubkey": "admin_public_key_hex",
+  "created_at": 1699123456,
+  "content": "C Nostr Relay Configuration",
+  "tags": [
+    ["d", "relay_public_key_hex"],
+    ["relay_description", "My Nostr Relay"],
+    ["max_subscriptions_per_client", "25"],
+    ["pow_min_difficulty", "16"]
+  ],
+  "sig": "signature_computed_with_admin_private_key"
+}
+```
+
+### Required Tags
+- **`d` tag**: Must contain the relay's public key (identifies which relay this config is for)
+
+### Event Properties
+- **Kind**: Must be exactly `33334`
+- **Content**: Should be descriptive (e.g., "C Nostr Relay Configuration")
+- **Pubkey**: Must be the admin public key generated at first startup
+- **Signature**: Must be valid signature from admin private key

+
+## Configuration Examples
+
+### Basic Relay Setup
+```json
+{
+  "kind": 33334,
+  "content": "Basic Relay Configuration",
+  "tags": [
+    ["d", "relay_pubkey_here"],
+    ["relay_description", "Community Nostr Relay"],
+    ["relay_contact", "admin@community-relay.com"],
+    ["max_subscriptions_per_client", "30"],
+    ["max_total_subscriptions", "8000"]
+  ]
+}
+```
+
+### High-Security Relay
+```json
+{
+  "kind": 33334,
+  "content": "High Security Configuration",
+  "tags": [
+    ["d", "relay_pubkey_here"],
+    ["relay_description", "High-Security Nostr Relay"],
+    ["pow_min_difficulty", "24"],
+    ["pow_mode", "required"],
+    ["max_subscriptions_per_client", "10"],
+    ["max_total_subscriptions", "1000"],
+    ["max_message_length", "32768"],
+    ["nip40_expiration_strict", "true"]
+  ]
+}
+```
+
+### Public Community Relay
+```json
+{
+  "kind": 33334,
+  "content": "Public Community Relay Configuration",
+  "tags": [
+    ["d", "relay_pubkey_here"],
+    ["relay_description", "Open Community Relay - Welcome Everyone!"],
+    ["relay_contact", "community@relay.example"],
+    ["max_subscriptions_per_client", "50"],
+    ["max_total_subscriptions", "25000"],
+    ["max_content_length", "131072"],
+    ["pow_mode", "optional"],
+    ["pow_min_difficulty", "8"],
+    ["nip40_expiration_enabled", "true"],
+    ["nip40_expiration_grace_period", "900"]
+  ]
+}
+```
+
+### Private/Corporate Relay
+```json
+{
+  "kind": 33334,
+  "content": "Corporate Internal Relay",
+  "tags": [
+    ["d", "relay_pubkey_here"],
+    ["relay_description", "Corporate Internal Communications"],
+    ["relay_contact", "it-admin@company.com"],
+    ["max_subscriptions_per_client", "20"],
+    ["max_total_subscriptions", "2000"],
+    ["max_message_length", "262144"],
+    ["nip40_expiration_enabled", "false"],
+    ["pow_mode", "disabled"]
+  ]
+}
+```
+
+## Security Considerations
+
+### Admin Key Management
+
+#### Secure Storage
+```bash
+# Store admin private key securely
+echo "ADMIN_PRIVKEY=your_admin_private_key_here" > .env
+chmod 600 .env
+
+# Or use a password manager
+# Never store in version control
+echo ".env" >> .gitignore
+```
+
+#### Key Rotation
+Currently, admin key rotation requires:
+1. Stopping the relay
+2. Removing the database (loses all events)
+3. Restarting (generates new keys)
+
+Future versions will support admin key rotation while preserving events.
+
+### Event Validation
+
+The relay performs comprehensive validation on configuration events:
+
+#### Cryptographic Validation
+- **Signature verification**: Uses `nostr_verify_event_signature()`
+- **Event structure**: Validates JSON structure with `nostr_validate_event_structure()`
+- **Admin authorization**: Ensures events are signed by the authorized admin pubkey
+
+#### Content Validation
+- **Parameter bounds checking**: Validates numeric ranges
+- **String length limits**: Enforces maximum lengths
+- **Enum validation**: Validates allowed values for mode parameters
+
+### Network Security
+
+#### Access Control
+```bash
+# Limit access with firewall
+sudo ufw allow from 192.168.1.0/24 to any port 8888
+
+# Or use specific IPs
+sudo ufw allow from 203.0.113.10 to any port 8888
+```
+
+#### TLS/SSL Termination
+```nginx
+# nginx configuration for HTTPS termination
+server {
+    listen 443 ssl;
+    server_name relay.example.com;
+    
+    ssl_certificate /path/to/cert.pem;
+    ssl_certificate_key /path/to/key.pem;
+    
+    location / {
+        proxy_pass http://127.0.0.1:8888;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection "Upgrade";
+        proxy_set_header Host $host;
+    }
+}
+```
+
+## Troubleshooting
+
+### Configuration Not Applied
+
+#### Check Event Signature
+```javascript
+// Verify event signature with nostrtool or similar
+const event = { /* your configuration event */ };
+const isValid = nostrTools.verifySignature(event);
+```
+
+#### Verify Admin Pubkey
+```bash
+# Check current admin pubkey in database
+sqlite3 relay.nrdb "SELECT DISTINCT pubkey FROM events WHERE kind = 33334 ORDER BY created_at DESC LIMIT 1;"
+
+# Compare with expected admin pubkey from first startup
+grep "Admin Public Key" relay.log
+```
+
+#### Check Event Structure
+```bash
+# View the exact event stored in database
+sqlite3 relay.nrdb "SELECT json_pretty(json_object(
+  'kind', kind,
+  'pubkey', pubkey, 
+  'created_at', created_at,
+  'content', content,
+  'tags', json(tags),
+  'sig', sig
+)) FROM events WHERE kind = 33334 ORDER BY created_at DESC LIMIT 1;"
+```
+
+### Configuration Validation Errors
+
+#### Invalid Parameter Values
+```bash
+# Check relay logs for validation errors
+journalctl -u c-relay | grep "Configuration.*invalid\|Invalid.*configuration"
+
+# Common issues:
+# - Numeric values outside valid ranges
+# - Invalid enum values (e.g., pow_mode)
+# - String values exceeding length limits
+```
+
+#### Missing Required Tags
+```bash
+# Ensure 'd' tag is present with relay pubkey
+sqlite3 relay.nrdb "SELECT tags FROM events WHERE kind = 33334 ORDER BY created_at DESC LIMIT 1;" | grep '"d"'
+```
+
+### Performance Impact
+
+#### Monitor Configuration Changes
+```bash
+# Track configuration update frequency
+sqlite3 relay.nrdb "SELECT datetime(created_at, 'unixepoch') as date, 
+  COUNT(*) as config_updates 
+FROM events WHERE kind = 33334 
+GROUP BY date(created_at, 'unixepoch') 
+ORDER BY date DESC;"
+```
+
+#### Resource Usage After Changes
+```bash
+# Monitor system resources after configuration updates
+top -p $(pgrep c_relay)
+
+# Check for memory leaks
+ps aux | grep c_relay | awk '{print $6}' # RSS memory
+```
+
+### Emergency Recovery
+
+#### Reset to Default Configuration
+If configuration becomes corrupted or causes issues:
+
+```bash
+# Create emergency configuration event
+nostrtool event \
+  --kind 33334 \
+  --content "Emergency Reset Configuration" \
+  --tag d YOUR_RELAY_PUBKEY \
+  --tag max_subscriptions_per_client 25 \
+  --tag max_total_subscriptions 5000 \
+  --tag pow_mode optional \
+  --tag pow_min_difficulty 0 \
+  --private-key YOUR_ADMIN_PRIVKEY \
+  | nostrtool send ws://localhost:8888
+```
+
+#### Database Recovery
+```bash
+# If database is corrupted, backup and recreate
+cp relay.nrdb relay.nrdb.backup
+rm relay.nrdb*
+./build/c_relay_x86  # Creates fresh database with new keys
+```
+
+---
+
+This configuration guide covers all aspects of managing the C Nostr Relay's event-based configuration system. The system provides unprecedented flexibility and security for Nostr relay administration while maintaining simplicity and real-time responsiveness.

+
+#endif /* DEFAULT_CONFIG_EVENT_H */
+```
+
+## Usage Notes
+
+1. **Isolation**: These default values are completely isolated from the rest of the program
+2. **Single Access Point**: Only accessed during `create_default_config_event()`
+3. **Runtime Keys**: Relay keys are added at runtime, not stored as defaults
+4. **No Direct Access**: Other parts of the program should never include this header directly
+5. **Clean Separation**: Keeps default configuration separate from configuration logic
+
+## Function Implementation
+
+The `create_default_config_event()` function will:
+
+1. Create a new cJSON event object with kind 33334
+2. Add all default configuration values as tags
+3. Add runtime-generated relay keys as tags
+4. Use `nostr_core_lib` to sign the event with admin private key
+5. Return the complete signed event ready for database storage
+
+This approach ensures clean separation between default values and the configuration system logic.

+# Event-Based Configuration System Implementation Plan
+
+## Overview
+
+This document provides a detailed implementation plan for transitioning the C Nostr Relay from command line arguments and file-based configuration to a pure event-based configuration system using kind 33334 Nostr events stored directly in the database.
+
+## Implementation Phases
+

+    {"auth_enabled", 0, apply_auth_enabled},
+    {"relay_port", 1, apply_relay_port},                    // requires restart
+    {"max_connections", 0, apply_max_connections},
+    {"relay_description", 0, apply_relay_description},
+    {"relay_contact", 0, apply_relay_contact},
+    {"relay_pubkey", 1, apply_relay_pubkey},                // requires restart
+    {"relay_privkey", 1, apply_relay_privkey},              // requires restart
+    {"pow_min_difficulty", 0, apply_pow_difficulty},
+    {"nip40_expiration_enabled", 0, apply_expiration_enabled},
+    {"max_subscriptions_per_client", 0, apply_max_subscriptions},
+    {"max_event_tags", 0, apply_max_event_tags},
+    {"max_content_length", 0, apply_max_content_length},

+};
+```
+
+#### 5.2 Startup Configuration Loading
+**File:** `src/main.c`
+
+```c
+int startup_existing_relay(const char* relay_pubkey) {
+    // 1. Open database
+    if (init_database_with_pubkey(relay_pubkey) != 0) {
+        return -1;
+    }
+    
+    // 2. Load configuration event from database
+    cJSON* config_event = load_config_event_from_database(relay_pubkey);
+    if (!config_event) {
+        log_error("No configuration event found in database");
+        return -1;
+    }
+    
+    // 3. Apply all configuration from event
+    if (apply_configuration_from_event(config_event) != 0) {
+        return -1;
+    }
+    
+    // 4. Continue with normal startup
+    return start_relay_services();
+}
+```
+
+## Implementation Order - PROGRESS STATUS
+
+### Step 1: Core Infrastructure ✅ COMPLETED
+1. ✅ Implement database naming with relay pubkey
+2. ✅ Add key generation functions using `nostr_core_lib`
+3. ✅ Create configuration event storage/retrieval functions
+4. ✅ Test basic event creation and storage
+
+### Step 2: Event Processing Integration ✅ MOSTLY COMPLETED

+2. ✅ Implement configuration event validation
+3. ⚠️ Create configuration application handlers (basic access implemented, runtime handlers pending)
+4. ⏳ Test real-time configuration updates (infrastructure ready)
+
+### Step 3: First-Time Startup ✅ COMPLETED
+1. ✅ Implement first-time startup detection
+2. ✅ Add automatic key generation and database creation
+3. ✅ Create default configuration event generation
+4. ✅ Test complete first-time startup flow
+
+### Step 4: Legacy Removal ⚠️ MOSTLY COMPLETED
+1. ✅ Remove command line argument parsing
+2. ✅ Remove configuration file system
+3. ⏳ Remove legacy database tables (pending)
+4. ✅ Update all references to use event-based config
+
+### Step 5: Testing and Validation ⚠️ PARTIALLY COMPLETED
+1. ✅ Test complete startup flow (first time and existing)
+2. ⏳ Test configuration updates via events (infrastructure ready)
+3. ⚠️ Test error handling and recovery (basic error handling implemented)
+4. ⏳ Performance testing and optimization (pending)
+
+## Migration Strategy
+
+### For Existing Installations
+Since the new system uses a completely different approach:
+
+1. **No Automatic Migration**: The new system starts fresh
+2. **Manual Migration**: Users can manually copy configuration values
+3. **Documentation**: Provide clear migration instructions
+4. **Coexistence**: Old and new systems use different database names
+
+### Migration Steps for Users
+1. Stop existing relay
+2. Note current configuration values
+3. Start new relay (generates keys and new database)
+4. Create kind 33334 event with desired configuration using admin private key
+5. Send event to relay to update configuration
+
+## Testing Requirements
+
+### Unit Tests
+- Key generation functions
+- Configuration event creation and validation
+- Database naming logic
+- Configuration application handlers
+
+### Integration Tests  
+- Complete first-time startup flow
+- Configuration update via events
+- Error handling scenarios
+- Database operations
+
+### Performance Tests
+- Startup time comparison
+- Configuration update response time
+- Memory usage analysis
+
+## Security Considerations
+
+1. **Admin Private Key**: Never stored, only printed once
+2. **Event Validation**: All configuration events must be signed by admin
+3. **Database Security**: Relay database contains relay private key
+4. **Key Generation**: Use `nostr_core_lib` for cryptographically secure generation
+
+## Files to Modify
+
+### Major Changes
+- `src/main.c` - Startup logic, event processing, argument removal
+- `src/config.c` - Complete rewrite for event-based configuration
+- `src/config.h` - Update function signatures and structures
+- `src/sql_schema.h` - Remove config tables
+
+### Minor Changes
+- `Makefile` - Remove any config file generation
+- `systemd/` - Update service files if needed
+- Documentation updates
+
+## Backwards Compatibility
+
+**Breaking Changes:**
+- Command line arguments removed (except --help, --version)
+- Configuration files no longer used
+- Database naming scheme changed
+- Configuration table removed
+
+**Migration Required:** This is a breaking change that requires manual migration for existing installations.
+
+## Success Criteria - CURRENT STATUS
+
+1. ✅ **Zero Command Line Arguments**: Relay starts with just `./c-relay`
+2. ✅ **Automatic First-Time Setup**: Generates keys and database automatically
+3. ⚠️ **Real-Time Configuration**: Infrastructure ready, handlers need completion
+4. ✅ **Single Database File**: All configuration and data in one `.nrdb` file
+5. ⚠️ **Admin Control**: Event processing implemented, signature validation ready
+6. ⚠️ **Clean Codebase**: Most legacy code removed, database tables cleanup pending
+
+## Risk Mitigation
+
+1. **Backup Strategy**: Document manual backup procedures for relay database
+2. **Key Loss Recovery**: Document recovery procedures if admin key is lost
+3. **Testing Coverage**: Comprehensive test suite before deployment
+4. **Rollback Plan**: Keep old version available during transition period
+5. **Documentation**: Comprehensive user and developer documentation
+
+This implementation plan provides a clear path from the current system to the new event-based configuration architecture while maintaining security and reliability.

-# File-Based Configuration Architecture Design
-
-## Overview
-This document outlines the XDG-compliant file-based configuration system for the C Nostr Relay, following the Ginxsom admin system approach using signed Nostr events.
-
-## XDG Base Directory Specification Compliance
-
-### File Location Strategy
-
-**Primary Location:**
-```
-$XDG_CONFIG_HOME/c-relay/c_relay_config_event.json
-```
-
-**Fallback Location:**
-```
-$HOME/.config/c-relay/c_relay_config_event.json
-```
-
-**System-wide Fallback:**
-```
-/etc/c-relay/c_relay_config_event.json
-```
-
-### Directory Structure
-```
-$XDG_CONFIG_HOME/c-relay/
-├── c_relay_config_event.json          # Main configuration file

-## Configuration File Format
-
-### Signed Nostr Event Structure
-
-The configuration file contains a signed Nostr event (kind 33334) with relay configuration:
-
-```json

-```
-
-### Event Kind Definition
-
-**Kind 33334**: C Nostr Relay Configuration Event
-- Parameterized replaceable event
-- Must be signed by authorized admin pubkey
-- Contains relay configuration as tags
-- Validation required on load
-
-## Configuration Loading Architecture
-
-### Loading Priority Chain
-
-1. **Command Line Arguments** (highest priority)
-2. **File-based Configuration** (signed Nostr event)
-3. **Database Configuration** (persistent storage)
-4. **Environment Variables** (compatibility mode)
-5. **Hardcoded Defaults** (fallback)

-    char file_path[512];
-    char file_hash[65];      // SHA256 hash
-    time_t last_modified;

-    int loaded_from_database;
-    char admin_pubkey[65];
-    time_t load_timestamp;
-} config_context_t;
-```
-
-### Core Function Signatures
-
-```c
-// XDG path resolution
-int get_config_file_path(char* path, size_t path_size);
-int create_config_directories(const char* config_path);
-
-// File operations

-int log_config_load_event(const config_context_t* ctx, const char* source);
-```
-
-## Configuration Validation Rules
-
-### Event Structure Validation
-
-1. **Required Fields**: `kind`, `created_at`, `tags`, `content`, `pubkey`, `id`, `sig`
-2. **Kind Validation**: Must be exactly 33334
-3. **Timestamp Validation**: Must be reasonable (not too old, not future)
-4. **Tags Format**: Array of string arrays `[["key", "value"], ...]`
-5. **Signature Verification**: Must be signed by authorized admin pubkey
-
-### Configuration Value Validation
-
-```c
-typedef struct {
-    char* key;
-    char* data_type;        // "string", "integer", "boolean", "json"
-    char* validation_rule;  // JSON validation rule
-    int required;
-    char* default_value;
-} config_validation_rule_t;
-
-static config_validation_rule_t validation_rules[] = {
-    {"relay_port", "integer", "{\"min\": 1, \"max\": 65535}", 1, "8888"},
-    {"pow_min_difficulty", "integer", "{\"min\": 0, \"max\": 64}", 1, "0"},
-    {"expiration_grace_period", "integer", "{\"min\": 0, \"max\": 86400}", 1, "300"},
-    {"admin_pubkey", "string", "{\"pattern\": \"^[0-9a-fA-F]{64}$\"}", 0, ""},
-    {"pow_enabled", "boolean", "{}", 1, "true"},
-    // ... more rules
-};
-```
-
-### Security Validation
-
-1. **Admin Pubkey Verification**: Only configured admin pubkeys can create config events
-2. **Event ID Verification**: Event ID must match computed hash
-3. **Signature Verification**: Signature must be valid for the event and pubkey
-4. **Timestamp Validation**: Prevent replay attacks with old events
-5. **File Permission Checks**: Config files should have appropriate permissions
-
-## File Management Features
-
-### Configuration File Operations
-
-**File Creation:**
-- Generate initial configuration file with default values
-- Sign with admin private key
-- Set appropriate file permissions (600 - owner read/write only)
-
-**File Updates:**
-- Create backup of existing file
-- Validate new configuration
-- Atomic file replacement (write to temp, then rename)
-- Update file metadata cache
-
-**File Monitoring:**
-- Watch for file system changes using inotify (Linux)
-- Reload configuration automatically when file changes
-- Validate changes before applying
-- Log all configuration reload events
-
-### Backup and Recovery
-
-**Automatic Backups:**
-```
-$XDG_CONFIG_HOME/c-relay/backup/
-├── c_relay_config_event.json.bak           # Last working config
-├── c_relay_config_event.20241205-143022.json # Timestamped backups
-└── c_relay_config_event.20241204-091530.json
-```
-
-**Recovery Process:**
-1. Detect corrupted or invalid config file
-2. Attempt to load from `.bak` backup
-3. If backup fails, generate default configuration
-4. Log recovery actions for audit
-
-## Integration with Database Schema
-
-### File-Database Synchronization
-
-**On File Load:**
-1. Parse and validate file-based configuration
-2. Extract configuration values from event tags
-3. Update database `server_config` table
-4. Record file metadata in `config_file_cache` table
-5. Log configuration changes in `config_history` table
-
-**Configuration Priority Resolution:**
-```c
-char* get_config_value(const char* key, const char* default_value) {
-    // Priority: CLI args > File config > DB config > Env vars > Default
-    char* value = NULL;
-    
-    // 1. Check command line overrides (if implemented)
-    value = get_cli_override(key);
-    if (value) return value;
-    
-    // 2. Check database (updated from file)
-    value = get_database_config(key);
-    if (value) return value;
-    
-    // 3. Check environment variables (compatibility)
-    value = get_env_config(key);
-    if (value) return value;
-    
-    // 4. Return default
-    return strdup(default_value);
-}
-```
-
-## Error Handling and Recovery
-
-### Validation Error Handling
-
-```c
-typedef enum {
-    CONFIG_ERROR_NONE = 0,
-    CONFIG_ERROR_FILE_NOT_FOUND = 1,
-    CONFIG_ERROR_PARSE_FAILED = 2,
-    CONFIG_ERROR_INVALID_STRUCTURE = 3,
-    CONFIG_ERROR_SIGNATURE_INVALID = 4,
-    CONFIG_ERROR_UNAUTHORIZED = 5,
-    CONFIG_ERROR_VALUE_INVALID = 6,
-    CONFIG_ERROR_IO_ERROR = 7
-} config_error_t;
-
-typedef struct {
-    config_error_t error_code;
-    char error_message[256];
-    char config_key[64];
-    char invalid_value[128];
-    time_t error_timestamp;
-} config_error_info_t;
-```
-
-### Graceful Degradation
-
-**File Load Failure:**
-1. Log detailed error information
-2. Fall back to database configuration
-3. Continue operation with last known good config
-4. Set service status to "degraded" mode
-
-**Validation Failure:**
-1. Log validation errors with specific details
-2. Skip invalid configuration items
-3. Use default values for failed items
-4. Continue with partial configuration
-
-**Permission Errors:**
-1. Log permission issues
-2. Attempt to use fallback locations
-3. Generate temporary config if needed
-4. Alert administrator via logs
-
-## Configuration Update Process
-
-### Safe Configuration Updates
-
-**Atomic Update Process:**
-1. Create backup of current configuration
-2. Write new configuration to temporary file
-3. Validate new configuration completely
-4. If valid, rename temporary file to active config
-5. Update database with new values
-6. Apply changes to running server
-7. Log successful update
-
-**Rollback Process:**
-1. Detect invalid configuration at startup
-2. Restore from backup file
-3. Log rollback event
-4. Continue with previous working configuration
-
-### Hot Reload Support
-
-**File Change Detection:**
-```c
-int monitor_config_file_changes(const char* config_path) {
-    // Use inotify on Linux to watch file changes
-    int inotify_fd = inotify_init();
-    int watch_fd = inotify_add_watch(inotify_fd, config_path, IN_MODIFY | IN_MOVED_TO);
-    
-    // Monitor in separate thread
-    // On change: validate -> apply -> log
-    return 0;
-}
-```
-
-**Runtime Configuration Updates:**
-- Reload configuration on file change
-- Apply non-restart-required changes immediately
-- Queue restart-required changes for next restart
-- Notify operators of configuration changes
-
-## Security Considerations
-
-### Access Control
-
-**File Permissions:**
-- Config files: 600 (owner read/write only)
-- Directories: 700 (owner access only)
-- Backup files: 600 (owner read/write only)
-
-**Admin Key Management:**
-- Admin private keys never stored in config files
-- Only admin pubkeys stored for verification
-- Support for multiple admin pubkeys
-- Key rotation support
-
-### Signature Validation
-
-**Event Signature Verification:**
-```c
-int verify_config_event_signature(const config_event_t* event, const char* admin_pubkey) {
-    // 1. Reconstruct event for signing (without id and sig)
-    // 2. Compute event ID and verify against stored ID
-    // 3. Verify signature using admin pubkey
-    // 4. Check admin pubkey authorization
-    return NOSTR_SUCCESS;
-}
-```
-
-**Anti-Replay Protection:**
-- Configuration events must be newer than current
-- Event timestamps validated against reasonable bounds
-- Configuration history prevents replay attacks
-

-
-## Configuration Generation Utilities
-
-### Interactive Setup Script
-
-```bash
-#!/bin/bash
-# scripts/setup_config.sh - Interactive configuration setup
-
-create_initial_config() {
-    echo "=== C Nostr Relay Initial Configuration ==="
-    
-    # Collect basic information
-    read -p "Relay name [C Nostr Relay]: " relay_name
-    read -p "Admin public key (hex): " admin_pubkey
-    read -p "Server port [8888]: " server_port
-    
-    # Generate signed configuration event
-    ./scripts/generate_config.sh \
-        --admin-key "$admin_pubkey" \
-        --relay-name "${relay_name:-C Nostr Relay}" \
-        --port "${server_port:-8888}" \
-        --output "$XDG_CONFIG_HOME/c-relay/c_relay_config_event.json"
-}
-```
-
-### Configuration Validation Utility
-
-```bash
-#!/bin/bash
-# scripts/validate_config.sh - Validate configuration file
-
-validate_config_file() {
-    local config_file="$1"
-    
-    # Check file exists and is readable
-    # Validate JSON structure
-    # Verify event signature
-    # Check configuration values
-    # Report validation results
-}
-```
-
-This comprehensive file-based configuration design provides a robust, secure, and maintainable system that follows industry standards while integrating seamlessly with the existing C Nostr Relay architecture.

+# Startup Configuration Design Analysis
+
+## Review of startup_config_design.md
+
+### Key Design Principles Identified
+
+1. **Zero Command Line Arguments**: Complete elimination of CLI arguments for true "quick start"
+2. **Event-Based Configuration**: Configuration stored as Nostr event (kind 33334) in events table
+3. **Self-Contained Database**: Database named after relay pubkey (`<pubkey>.nrdb`)
+4. **First-Time Setup**: Automatic key generation and initial configuration creation
+5. **Configuration Consistency**: Always read from event, never from hardcoded defaults
+
+### Implementation Gaps and Specifications Needed
+
+#### 1. Key Generation Process
+**Specification:**
+```
+First Startup Key Generation:
+1. Generate all keys on first startup (admin private/public, relay private/public)
+2. Use nostr_core_lib for key generation entropy
+3. Keys are encoded in hex format
+4. Print admin private key to stdout for user to save (never stored)
+5. Store admin public key, relay private key, and relay public key in configuration event
+6. Admin can later change the 33334 event to alter stored keys
+```
+
+#### 2. Database Naming and Location
+**Specification:**
+```
+Database Naming:
+1. Database is named using relay pubkey: ./<relay_pubkey>.nrdb
+2. Database path structure: ./<relay_pubkey>.nrdb
+3. If database creation fails, program quits (can't run without database)
+4. c_nostr_relay.db should never exist in new system
+```
+
+#### 3. Configuration Event Structure (Kind 33334)
+**Specification:**
+```
+Event Structure:
+- Kind: 33334 (parameterized replaceable event)
+- Event validation: Use nostr_core_lib to validate event
+- Event content field: "C Nostr Relay Configuration" (descriptive text)
+- Configuration update mechanism: TBD
+- Complete tag structure provided in configuration section below
+```
+
+
+
+#### 4. Configuration Change Monitoring
+**Configuration Monitoring System:**
+```
+Every event that is received is checked to see if it is a kind 33334 event from the admin pubkey.
+If so, it is processed as a configuration update.
+```
+
+#### 5. Error Handling and Recovery
+**Specification:**
+```
+Error Recovery Priority:
+1. Try to load latest valid config event
+2. Generate new default configuration event if none exists
+3. Exit with error if all recovery attempts fail
+
+Note: There is only ever one configuration event (parameterized replaceable event),
+so no fallback to previous versions.
+```
+
+### Design Clarifications
+
+**Key Management:**
+- Admin private key is never stored, only printed once at first startup
+- Single admin system (no multi-admin support)
+- No key rotation support
+
+**Configuration Management:**
+- No configuration versioning/timestamping
+- No automatic backup of configuration events
+- Configuration events are not broadcastable to other relays
+- Future: Auth system to restrict admin access to configuration events
+
+---
+
+## Complete Current Configuration Structure
+
+Based on analysis of [`src/config.c`](src/config.c:753-795), here is the complete current configuration structure that will be converted to event tags:
+
+### Complete Event Structure Example
+```json
+{
+  "kind": 33334,
+  "created_at": 1725661483,
+  "tags": [
+    ["d", "<relay_pubkey>"],
+    ["auth_enabled", "false"],
+    ["relay_port", "8888"],
+    ["max_connections", "100"],
+
+    ["relay_description", "High-performance C Nostr relay with SQLite storage"],
+    ["relay_contact", ""],
+    ["relay_pubkey", "<relay_public_key>"],
+    ["relay_privkey", "<relay_private_key>"],
+    ["relay_software", "https://git.laantungir.net/laantungir/c-relay.git"],
+    ["relay_version", "v1.0.0"],
+  
+    ["pow_min_difficulty", "0"],
+    ["pow_mode", "basic"],
+    ["nip40_expiration_enabled", "true"],
+    ["nip40_expiration_strict", "true"],
+    ["nip40_expiration_filter", "true"],
+    ["nip40_expiration_grace_period", "300"],
+    ["max_subscriptions_per_client", "25"],
+    ["max_total_subscriptions", "5000"],
+    ["max_filters_per_subscription", "10"],
+    ["max_event_tags", "100"],
+    ["max_content_length", "8196"],
+    ["max_message_length", "16384"],
+    ["default_limit", "500"],
+    ["max_limit", "5000"]
+  ],
+  "content": "C Nostr Relay Configuration",
+  "pubkey": "<admin_public_key>",
+  "id": "<computed_event_id>",
+  "sig": "<event_signature>"
+}
+```
+
+**Note:** The `admin_pubkey` tag is omitted as it's redundant with the event's `pubkey` field.

+# Startup and configuration for c_nostr_relay
+
+No command line variables. Quick start.
+
+## First time startup
+When the program first starts, it generates a new private and public keys for the program, and for the admin. In the command line it prints out the private key for the admin. It creates a database in the same directory as the application. It names the database after the pubkey of the database <pubkey>.nrdb (This stands for nostr relay db)
+
+Internally, it creates a valid nostr event using the generated admin private key, and saves it to the events table in the db. That nostr configuration event is a type 33334 event, with a d tag that equals the database public key d=<db pubkey>. 
+
+The event is populated from internal default values. Then the configuration setup is run by reading the event from the database events table.
+
+Important, the constant values are ALWAYS read and set from the 33334 event in the events table, they are NEVER read from the stored default values. This is important for consistancy.
+
+The config section of the program keeps track of the admin file, and if it ever changes, it does what is needed to implement the change.
+
+
+## Later startups
+The program looks for the database with the name c_nostr_relay.db in the same directory as the program. If it doesn't find it, it assumes a first time startup. If it does find it, it loads the database, and the config section reads the config event and proceedes from there.
+
+## Changing database location?
+Changing the location of the databases can be done by creating a sym-link to the new location of the database.

+## Quick Start
+
+### 1. Build and Start
+```bash
+# Clone and build
+git clone <repository-url>
+cd c-relay
+git submodule update --init --recursive
+make
+
+# Start relay (zero configuration needed)
+./build/c_relay_x86
+```
+
+### 2. First Startup - Save Keys
+The relay will display admin keys on first startup:
+
+```
+=================================================================
+IMPORTANT: SAVE THIS ADMIN PRIVATE KEY SECURELY!
+=================================================================
+Admin Private Key: a018ecc259ff296ef7aaca6cdccbc52cf28104ac7a1f14c27b0b8232e5025ddc
+Admin Public Key:  68394d08ab87f936a42ff2deb15a84fbdfbe0996ee0eb20cda064aae673285d1
+=================================================================
+```
+
+⚠️ **CRITICAL**: Save the admin private key - it's needed for configuration updates and only shown once!
+

+
+# Run as service user
+sudo -u c-relay /opt/c-relay/c_relay_x86
+```
+
+## Configuration Management
+
+### Event-Based Configuration System
+
+Unlike traditional relays that use config files, this relay stores all configuration as **kind 33334 Nostr events** in the database. This provides:
+
+- **Real-time updates**: Changes applied instantly without restart
+- **Cryptographic security**: All config changes must be signed by admin
+- **Audit trail**: Complete history of configuration changes
+- **No file management**: No config files to manage or version control
+
+### First-Time Configuration
+
+On first startup, the relay:
+
+1. **Generates keypairs**: Creates cryptographically secure admin and relay keys
+2. **Creates database**: `<relay_pubkey>.nrdb` file with optimized schema
+3. **Stores default config**: Creates initial kind 33334 event with sensible defaults
+4. **Displays admin key**: Shows admin private key once for you to save
+
+### Updating Configuration
+
+To change relay configuration, create and send a signed kind 33334 event:
+
+#### Using nostrtool (recommended)
+```bash
+# Install nostrtool
+npm install -g nostrtool
+
+# Update relay description
+nostrtool event \
+  --kind 33334 \
+  --content "C Nostr Relay Configuration" \
+  --tag d <relay_pubkey> \
+  --tag relay_description "My Production Relay" \
+  --tag max_subscriptions_per_client 50 \
+  --private-key <admin_private_key> \
+  | nostrtool send ws://localhost:8888
+```
+
+#### Manual Event Creation
+```json
+{
+  "kind": 33334,
+  "content": "C Nostr Relay Configuration",
+  "tags": [
+    ["d", "<relay_pubkey>"],
+    ["relay_description", "My Production Relay"],
+    ["max_subscriptions_per_client", "50"],
+    ["pow_min_difficulty", "20"]
+  ],
+  "created_at": 1699123456,
+  "pubkey": "<admin_pubkey>",
+  "id": "<computed_event_id>",
+  "sig": "<signature>"
+}
+```
+
+Send this to your relay via WebSocket, and changes are applied immediately.

+## Web Admin Interface
+
+The relay includes a built-in web-based administration interface that provides a user-friendly way to manage your relay without command-line tools.
+
+### Accessing the Interface
+
+1. **Open your browser** and navigate to: `http://localhost:8888/api/`
+2. **Authenticate** using your Nostr identity (the admin interface uses NIP-42 authentication)
+3. **Manage configuration** through the web interface
+
+### Features
+
+- **Real-time Configuration**: View and edit all relay settings
+- **Database Statistics**: Monitor event counts, storage usage, and performance metrics
+- **Auth Rules Management**: Configure whitelist/blacklist rules for pubkeys
+- **Relay Connection Testing**: Verify WebSocket connectivity and NIP-11 information
+- **Event-Based Updates**: All changes are applied as signed Nostr events
+
+### Security Notes
+
+- The web interface requires NIP-42 authentication with your admin pubkey
+- All configuration changes are cryptographically signed
+- The interface serves embedded static files (no external dependencies)
+- CORS headers are included for proper browser operation
+
+### Browser Compatibility
+
+The admin interface works with modern browsers that support:
+- WebSocket connections
+- ES6 JavaScript features
+- Modern CSS Grid and Flexbox layouts
+
+## Administration
+
+### Viewing Current Configuration
+```bash
+# Find your database
+ls -la *.nrdb
+
+# View configuration events
+sqlite3 <relay_pubkey>.nrdb "SELECT created_at, tags FROM events WHERE kind = 33334 ORDER BY created_at DESC LIMIT 1;"
+
+# View all configuration history
+sqlite3 <relay_pubkey>.nrdb "SELECT datetime(created_at, 'unixepoch') as date, tags FROM events WHERE kind = 33334 ORDER BY created_at DESC;"
+```
+
+### Admin Key Management
+
+#### Backup Admin Keys
+```bash
+# Create secure backup
+echo "Admin Private Key: <your_admin_key>" > admin_keys_backup_$(date +%Y%m%d).txt
+chmod 600 admin_keys_backup_*.txt
+
+# Store in secure location (password manager, encrypted drive, etc.)
+```
+
+#### Key Recovery
+If you lose your admin private key:
+
+1. **Stop the relay**: `pkill c_relay` or `sudo systemctl stop c-relay`
+2. **Backup events**: `cp <relay_pubkey>.nrdb backup_$(date +%Y%m%d).nrdb`
+3. **Remove database**: `rm <relay_pubkey>.nrdb*`
+4. **Restart relay**: This creates new database with new keys
+5. **⚠️ Note**: All stored events and configuration history will be lost
+
+### Security Best Practices
+
+#### Admin Key Security
+- **Never share** the admin private key
+- **Store securely** in password manager or encrypted storage
+- **Backup safely** to multiple secure locations
+- **Monitor** configuration changes in logs
+
+#### Network Security
+```bash
+# Restrict access with firewall
+sudo ufw allow 8888/tcp
+
+# Use reverse proxy for HTTPS (recommended)
+# Configure nginx/apache to proxy to ws://localhost:8888
+```
+
+#### Database Security
+```bash
+# Secure database file permissions
+chmod 600 <relay_pubkey>.nrdb
+chown c-relay:c-relay <relay_pubkey>.nrdb
+
+# Regular backups
+cp <relay_pubkey>.nrdb backup/relay_backup_$(date +%Y%m%d_%H%M%S).nrdb
+```
+
+## Monitoring
+
+### Service Status
+```bash
+# Check if relay is running
+ps aux | grep c_relay
+
+# SystemD status
+sudo systemctl status c-relay
+
+# Network connections
+netstat -tln | grep 8888
+sudo ss -tlpn | grep 8888
+```
+
+### Log Monitoring
+```bash
+# Real-time logs (systemd)
+sudo journalctl -u c-relay -f
+
+# Recent logs
+sudo journalctl -u c-relay --since "1 hour ago"
+
+# Error logs only
+sudo journalctl -u c-relay -p err
+
+# Configuration changes
+sudo journalctl -u c-relay | grep "Configuration updated via kind 33334"
+```
+
+### Database Analytics
+```bash
+# Connect to database
+sqlite3 <relay_pubkey>.nrdb
+
+# Event statistics
+SELECT event_type, COUNT(*) as count FROM events GROUP BY event_type;
+
+# Recent activity
+SELECT datetime(created_at, 'unixepoch') as date, kind, LENGTH(content) as content_size 
+FROM events 
+ORDER BY created_at DESC 
+LIMIT 10;
+
+# Subscription analytics (if logging enabled)
+SELECT * FROM subscription_analytics ORDER BY date DESC LIMIT 7;
+
+# Configuration changes
+SELECT datetime(created_at, 'unixepoch') as date, tags 
+FROM configuration_events 
+ORDER BY created_at DESC;
+```
+
+### Performance Monitoring
+```bash
+# Database size
+du -sh <relay_pubkey>.nrdb*
+
+# Memory usage
+ps aux | grep c_relay | awk '{print $6}' # RSS memory in KB
+
+# Connection count (approximate)
+netstat -an | grep :8888 | grep ESTABLISHED | wc -l
+
+# System resources
+top -p $(pgrep c_relay)
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### Relay Won't Start
+```bash
+# Check port availability
+netstat -tln | grep 8888
+# If port in use, find process: sudo lsof -i :8888
+
+# Check binary permissions
+ls -la build/c_relay_x86
+chmod +x build/c_relay_x86
+
+# Check dependencies
+ldd build/c_relay_x86
+```
+
+#### Configuration Not Updating
+1. **Verify signature**: Ensure event is properly signed with admin private key
+2. **Check admin pubkey**: Must match the pubkey from first startup
+3. **Validate event structure**: Use `nostrtool validate` or similar
+4. **Check logs**: Look for validation errors in relay logs
+5. **Test WebSocket**: Ensure WebSocket connection is active
+
+```bash
+# Test WebSocket connection
+wscat -c ws://localhost:8888
+
+# Send test message
+{"id":"test","method":"REQ","params":["test",{}]}
+```
+
+#### Database Issues
+```bash
+# Check database integrity
+sqlite3 <relay_pubkey>.nrdb "PRAGMA integrity_check;"
+
+# Check schema version
+sqlite3 <relay_pubkey>.nrdb "SELECT * FROM schema_info WHERE key = 'version';"
+
+# View database size and stats
+sqlite3 <relay_pubkey>.nrdb "PRAGMA page_size; PRAGMA page_count;"
+```
+
+#### Performance Issues
+```bash
+# Analyze slow queries (if any)
+sqlite3 <relay_pubkey>.nrdb "PRAGMA compile_options;"
+
+# Check database optimization
+sqlite3 <relay_pubkey>.nrdb "PRAGMA optimize;"
+
+# Monitor system resources
+iostat 1 5  # I/O statistics
+free -h     # Memory usage
+```
+
+### Recovery Procedures
+
+#### Corrupted Database Recovery
+```bash
+# Attempt repair
+sqlite3 <relay_pubkey>.nrdb ".recover" > recovered.sql
+sqlite3 recovered.nrdb < recovered.sql
+
+# If repair fails, start fresh (loses all events)
+mv <relay_pubkey>.nrdb <relay_pubkey>.nrdb.corrupted
+./build/c_relay_x86  # Creates new database
+```
+
+#### Lost Configuration Recovery
+If configuration is lost but database is intact:
+
+1. **Find old config**: `sqlite3 <relay_pubkey>.nrdb "SELECT * FROM configuration_events;"`
+2. **Create new config event**: Use last known good configuration
+3. **Sign and send**: Update with current timestamp and new signature
+
+#### Emergency Restart
+```bash
+# Quick restart with clean state
+sudo systemctl stop c-relay
+mv <relay_pubkey>.nrdb <relay_pubkey>.nrdb.backup
+sudo systemctl start c-relay
+
+# Check logs for new admin keys
+sudo journalctl -u c-relay --since "5 minutes ago" | grep "Admin Private Key"
+```
+
+## Advanced Usage
+
+### Custom Event Handlers
+The relay supports custom handling for different event types. Configuration changes trigger:
+
+- **Subscription Manager Updates**: When client limits change
+- **PoW System Reinitialization**: When PoW settings change
+- **Expiration System Updates**: When NIP-40 settings change
+- **Relay Info Updates**: When NIP-11 information changes
+
+### API Integration
+```javascript
+// Connect and send configuration update
+const ws = new WebSocket('ws://localhost:8888');
+
+ws.on('open', function() {
+  const configEvent = {
+    kind: 33334,
+    content: "Updated configuration",
+    tags: [
+      ["d", relayPubkey],
+      ["relay_description", "Updated via API"]
+    ],
+    created_at: Math.floor(Date.now() / 1000),
+    pubkey: adminPubkey,
+    // ... add id and sig
+  };
+  
+  ws.send(JSON.stringify(["EVENT", configEvent]));
+});
+```
+
+### Backup Strategies
+
+#### Automated Backup
+```bash
+#!/bin/bash
+# backup-relay.sh
+DATE=$(date +%Y%m%d_%H%M%S)
+DB_FILE=$(ls *.nrdb | head -1)
+BACKUP_DIR="/backup/c-relay"
+
+mkdir -p $BACKUP_DIR
+cp $DB_FILE $BACKUP_DIR/relay_backup_$DATE.nrdb
+gzip $BACKUP_DIR/relay_backup_$DATE.nrdb
+
+# Cleanup old backups (keep 30 days)
+find $BACKUP_DIR -name "relay_backup_*.nrdb.gz" -mtime +30 -delete
+```
+
+#### Configuration Export
+```bash
+# Export configuration events
+sqlite3 <relay_pubkey>.nrdb "SELECT json_object(
+  'kind', kind,
+  'content', content,
+  'tags', json(tags),
+  'created_at', created_at,
+  'pubkey', pubkey,
+  'sig', sig
+) FROM events WHERE kind = 33334 ORDER BY created_at;" > config_backup.json
+```
+
+### Migration Between Servers
+```bash
+# Source server
+tar czf relay_migration.tar.gz *.nrdb* relay.log
+
+# Target server  
+tar xzf relay_migration.tar.gz
+./build/c_relay_x86  # Will detect existing database and continue
+```

+
+## Quick Start Examples
+
+### 1. Simple VPS Deployment
+For a basic Ubuntu VPS deployment:
+```bash
+cd examples/deployment/simple-vps
+chmod +x deploy.sh
+sudo ./deploy.sh
+```
+
+### 2. SSL Proxy Setup
+For nginx reverse proxy with SSL:
+```bash
+cd examples/deployment/nginx-proxy
+chmod +x setup-ssl-proxy.sh
+sudo ./setup-ssl-proxy.sh -d relay.example.com -e admin@example.com
+```
+
+### 3. Monitoring Setup
+For continuous monitoring:

+cd examples/deployment/backup
+chmod +x backup-relay.sh
+sudo ./backup-relay.sh -s my-backup-bucket -e admin@example.com
+```
+
+## Configuration Examples
+
+All examples assume the event-based configuration system where:
+- No config files are needed
+- Configuration is stored as kind 33334 events in the database
+- Admin keys are generated on first startup
+- Database naming uses relay pubkey (`<relay_pubkey>.nrdb`)
+
+## Security Notes
+
+- **Save Admin Keys**: All deployment examples emphasize capturing the admin private key on first startup
+- **Firewall Configuration**: Examples include proper firewall rules
+- **SSL/TLS**: Production examples include HTTPS configuration
+- **User Isolation**: Service runs as dedicated `c-relay` system user
+
+## Support
+

+```
+
+#### Encrypt with AES-256-GCM
+
+```js
+import { gcm } from '@noble/ciphers/aes';
+import { utf8ToBytes } from '@noble/ciphers/utils';
+import { randomBytes } from '@noble/ciphers/webcrypto';
+const key = randomBytes(32);

+const data = utf8ToBytes('hello, noble');
+const ciphertext = aes.encrypt(data);
+const data_ = aes.decrypt(ciphertext); // utils.bytesToUtf8(data_) === data
+```
+
+#### Use existing key instead of a new one
+
+```js
+const key = new Uint8Array([
+  169, 88, 160, 139, 168, 29, 147, 196, 14, 88, 237, 76, 243, 177, 109, 140, 195, 140, 80, 10, 216,
+  134, 215, 71, 191, 48, 20, 104, 189, 37, 38, 55,
+]);
+const nonce = new Uint8Array([
+  180, 90, 27, 63, 160, 191, 150, 33, 67, 212, 86, 71, 144, 6, 200, 102, 218, 32, 23, 147, 8, 41,
+  147, 11,
+]);
+// or, hex:
+import { hexToBytes } from '@noble/ciphers/utils';
+const key2 = hexToBytes('4b7f89bac90a1086fef73f5da2cbe93b2fae9dfbf7678ae1f3e75fd118ddf999');
+const nonce2 = hexToBytes('9610467513de0bbd7c4cc2c3c64069f1802086fbd3232b13');
+```
+
+#### Encrypt without nonce
+
+```js
+import { xchacha20poly1305 } from '@noble/ciphers/chacha';
+import { managedNonce } from '@noble/ciphers/webcrypto';
+import { hexToBytes, utf8ToBytes } from '@noble/ciphers/utils';
+const key = hexToBytes('fa686bfdffd3758f6377abbc23bf3d9bdc1a0dda4a6e7f8dbdd579fa1ff6d7e1');
+const chacha = managedNonce(xchacha20poly1305)(key); // manages nonces for you
+const data = utf8ToBytes('hello, noble');
+const ciphertext = chacha.encrypt(data);
+const data_ = chacha.decrypt(ciphertext);
+```
+
+#### Use same array for input and output
+
+```js
+import { chacha20poly1305 } from '@noble/ciphers/chacha';
+import { utf8ToBytes } from '@noble/ciphers/utils';
+import { randomBytes } from '@noble/ciphers/webcrypto';
+
+const key = randomBytes(32);
+const nonce = randomBytes(12);
+const buf = new Uint8Array(12 + 16);
+const _data = utf8ToBytes('hello, noble');
+buf.set(_data, 0); // first 12 bytes
+const _12b = buf.subarray(0, 12);
+
+const chacha = chacha20poly1305(key, nonce);
+chacha.encrypt(_12b, buf);
+chacha.decrypt(buf, _12b); // _12b now same as _data
+```
+
+#### All imports
+
+```js
+import { gcm, siv } from '@noble/ciphers/aes';
+import { xsalsa20poly1305 } from '@noble/ciphers/salsa';
+import { chacha20poly1305, xchacha20poly1305 } from '@noble/ciphers/chacha';
+

+
+## Implementations
+
+### Salsa
+
+```js
+import { xsalsa20poly1305 } from '@noble/ciphers/salsa';
+import { secretbox } from '@noble/ciphers/salsa'; // == xsalsa20poly1305
+import { salsa20, xsalsa20 } from '@noble/ciphers/salsa';
+```
+
+[Salsa20](https://cr.yp.to/snuffle.html) stream cipher was released in 2005.
+Salsa's goal was to implement AES replacement that does not rely on S-Boxes,
+which are hard to implement in a constant-time manner.
+Salsa20 is usually faster than AES, a big deal on slow, budget mobile phones.
+
+[XSalsa20](https://cr.yp.to/snuffle/xsalsa-20110204.pdf), extended-nonce
+variant was released in 2008. It switched nonces from 96-bit to 192-bit,
+and became safe to be picked at random.
+
+Nacl / Libsodium popularized term "secretbox", a simple black-box
+authenticated encryption. Secretbox is just xsalsa20-poly1305. We provide the
+alias and corresponding seal / open methods. We don't provide "box" or "sealedbox".
+
+Check out [PDF](https://cr.yp.to/snuffle/salsafamily-20071225.pdf) and
+[wiki](https://en.wikipedia.org/wiki/Salsa20).
+
+### ChaCha
+
+```js
+import { chacha20poly1305, xchacha20poly1305 } from '@noble/ciphers/chacha';
+import { chacha20, xchacha20, chacha8, chacha12 } from '@noble/ciphers/chacha';
+```
+
+[ChaCha20](https://cr.yp.to/chacha.html) stream cipher was released
+in 2008. ChaCha aims to increase the diffusion per round, but had slightly less
+cryptanalysis. It was standardized in
+[RFC 8439](https://datatracker.ietf.org/doc/html/rfc8439) and is now used in TLS 1.3.
+
+[XChaCha20](https://datatracker.ietf.org/doc/html/draft-irtf-cfrg-xchacha)
+extended-nonce variant is also provided. Similar to XSalsa, it's safe to use with
+randomly-generated nonces.
+
+Check out [PDF](http://cr.yp.to/chacha/chacha-20080128.pdf) and [wiki](https://en.wikipedia.org/wiki/Salsa20).
+
+### AES
+
+```js
+import { gcm, siv, ctr, cfb, cbc, ecb } from '@noble/ciphers/aes';
+import { randomBytes } from '@noble/ciphers/webcrypto';
+const plaintext = new Uint8Array(32).fill(16);
+const key = randomBytes(32); // 24 for AES-192, 16 for AES-128
+for (let cipher of [gcm, siv]) {
+  const stream = cipher(key, randomBytes(12));
+  const ciphertext_ = stream.encrypt(plaintext);
+  const plaintext_ = stream.decrypt(ciphertext_);
+}
+for (const cipher of [ctr, cbc, cbc]) {
+  const stream = cipher(key, randomBytes(16));
+  const ciphertext_ = stream.encrypt(plaintext);
+  const plaintext_ = stream.decrypt(ciphertext_);
+}
+for (const cipher of [ecb]) {
+  const stream = cipher(key);
+  const ciphertext_ = stream.encrypt(plaintext);
+  const plaintext_ = stream.decrypt(ciphertext_);
+}
+```
+
+[AES](https://en.wikipedia.org/wiki/Advanced_Encryption_Standard)
+is a variant of Rijndael block cipher, standardized by NIST in 2001.
+We provide the fastest available pure JS implementation.
+
+We support AES-128, AES-192 and AES-256: the mode is selected dynamically,
+based on key length (16, 24, 32).
+
+[AES-GCM-SIV](https://en.wikipedia.org/wiki/AES-GCM-SIV)
+nonce-misuse-resistant mode is also provided. It's recommended to use it,
+to prevent catastrophic consequences of nonce reuse. Our implementation of SIV
+has the same speed as GCM: there is no performance hit.
+
+Check out [AES internals and block modes](#aes-internals-and-block-modes).
+
+### Webcrypto AES
+
+```js
+import { gcm, ctr, cbc, randomBytes } from '@noble/ciphers/webcrypto';
+const plaintext = new Uint8Array(32).fill(16);
+const key = randomBytes(32);
+for (const cipher of [gcm]) {
+  const stream = cipher(key, randomBytes(12));
+  const ciphertext_ = await stream.encrypt(plaintext);
+  const plaintext_ = await stream.decrypt(ciphertext_);
+}
+for (const cipher of [ctr, cbc]) {
+  const stream = cipher(key, randomBytes(16));
+  const ciphertext_ = await stream.encrypt(plaintext);
+  const plaintext_ = await stream.decrypt(ciphertext_);
+}
+```
+
+We also have a separate wrapper over WebCrypto built-in.
+
+It's the same as using `crypto.subtle`, but with massively simplified API.
+
+Unlike pure js version, it's asynchronous.
+
+### Poly1305, GHash, Polyval
+
+```js
+import { poly1305 } from '@noble/ciphers/_poly1305';
+import { ghash, polyval } from '@noble/ciphers/_polyval';
+```
+
+We expose polynomial-evaluation MACs: [Poly1305](https://cr.yp.to/mac.html),
+AES-GCM's [GHash](https://en.wikipedia.org/wiki/Galois/Counter_Mode) and
+AES-SIV's [Polyval](https://en.wikipedia.org/wiki/AES-GCM-SIV).
+
+Poly1305 ([PDF](https://cr.yp.to/mac/poly1305-20050329.pdf),
+[wiki](https://en.wikipedia.org/wiki/Poly1305))
+is a fast and parallel secret-key message-authentication code suitable for
+a wide variety of applications. It was standardized in
+[RFC 8439](https://datatracker.ietf.org/doc/html/rfc8439) and is now used in TLS 1.3.
+
+Polynomial MACs are not perfect for every situation:
+they lack Random Key Robustness: the MAC can be forged, and can't
+be used in PAKE schemes. See
+[invisible salamanders attack](https://keymaterial.net/2020/09/07/invisible-salamanders-in-aes-gcm-siv/).
+To combat invisible salamanders, `hash(key)` can be included in ciphertext,
+however, this would violate ciphertext indistinguishability:
+an attacker would know which key was used - so `HKDF(key, i)`
+could be used instead.
+
+### FF1
+
+Format-preserving encryption algorithm (FPE-FF1) specified in NIST Special Publication 800-38G.
+[See more info](https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-38G.pdf).
+
+### Managed nonces
+
+```js
+import { managedNonce } from '@noble/ciphers/webcrypto';
+import { gcm, siv, ctr, cbc, cbc, ecb } from '@noble/ciphers/aes';
+import { xsalsa20poly1305 } from '@noble/ciphers/salsa';
+import { chacha20poly1305, xchacha20poly1305 } from '@noble/ciphers/chacha';
+
+const wgcm = managedNonce(gcm);
+const wsiv = managedNonce(siv);
+const wcbc = managedNonce(cbc);
+const wctr = managedNonce(ctr);
+const wsalsapoly = managedNonce(xsalsa20poly1305);
+const wchacha = managedNonce(chacha20poly1305);
+const wxchacha = managedNonce(xchacha20poly1305);
+
+// Now:
+const encrypted = wgcm(key).encrypt(data); // no nonces
+```
+
+We provide API that manages nonce internally instead of exposing them to library's user.
+
+For `encrypt`, a `nonceBytes`-length buffer is fetched from CSPRNG and prenended to encrypted ciphertext.
+
+For `decrypt`, first `nonceBytes` of ciphertext are treated as nonce.
+
+## Guidance
+
+### Which cipher should I pick?
+
+XChaCha20-Poly1305 is the safest bet these days.
+AES-GCM-SIV is the second safest.
+AES-GCM is the third.
+
+### How to encrypt properly
+
+- Use unpredictable key with enough entropy
+  - Random key must be using cryptographically secure random number generator (CSPRNG), not `Math.random` etc.
+  - Non-random key generated from KDF is fine
+  - Re-using key is fine, but be aware of rules for cryptographic key wear-out and [encryption limits](#encryption-limits)
+- Use new nonce every time and [don't repeat it](#nonces)
+  - chacha and salsa20 are fine for sequential counters that _never_ repeat: `01, 02...`
+  - xchacha and xsalsa20 should be used for random nonces instead
+- Prefer authenticated encryption (AEAD)
+  - HMAC+ChaCha / HMAC+AES / chacha20poly1305 / aes-gcm is good
+  - chacha20 without poly1305 or hmac / aes-ctr / aes-cbc is bad
+  - Flipping bits or ciphertext substitution won't be detected in unauthenticated ciphers
+- Don't re-use keys between different protocols
+  - For example, using secp256k1 key in AES is bad
+  - Use hkdf or, at least, a hash function to create sub-key instead
+
+### Nonces
+
+Most ciphers need a key and a nonce (aka initialization vector / IV) to encrypt a data:
+
+    ciphertext = encrypt(plaintext, key, nonce)
+
+Repeating (key, nonce) pair with different plaintexts would allow an attacker to decrypt it:
+
+    ciphertext_a = encrypt(plaintext_a, key, nonce)
+    ciphertext_b = encrypt(plaintext_b, key, nonce)
+    stream_diff = xor(ciphertext_a, ciphertext_b)   # Break encryption
+
+So, you can't repeat nonces. One way of doing so is using counters:
+
+    for i in 0..:
+        ciphertext[i] = encrypt(plaintexts[i], key, i)
+
+Another is generating random nonce every time:
+
+    for i in 0..:
+        rand_nonces[i] = random()
+        ciphertext[i] = encrypt(plaintexts[i], key, rand_nonces[i])
+
+Counters are OK, but it's not always possible to store current counter value:
+e.g. in decentralized, unsyncable systems.
+
+Randomness is OK, but there's a catch:
+ChaCha20 and AES-GCM use 96-bit / 12-byte nonces, which implies
+higher chance of collision. In the example above,
+`random()` can collide and produce repeating nonce.
+
+To safely use random nonces, utilize XSalsa20 or XChaCha:
+they increased nonce length to 192-bit, minimizing a chance of collision.
+AES-SIV is also fine. In situations where you can't use eXtended-nonce
+algorithms, key rotation is advised. hkdf would work great for this case.
+
+### Encryption limits
+
+A "protected message" would mean a probability of `2**-50` that a passive attacker
+successfully distinguishes the ciphertext outputs of the AEAD scheme from the outputs
+of a random function. See [draft-irtf-cfrg-aead-limits](https://datatracker.ietf.org/doc/draft-irtf-cfrg-aead-limits/) for details.
+
+- Max message size:
+  - AES-GCM: ~68GB, `2**36-256`
+  - Salsa, ChaCha, XSalsa, XChaCha: ~256GB, `2**38-64`
+- Max amount of protected messages, under same key:
+  - AES-GCM: `2**32.5`
+  - Salsa, ChaCha: `2**46`, but only integrity is affected, not confidentiality
+  - XSalsa, XChaCha: `2**72`
+- Max amount of protected messages, across all keys:
+  - AES-GCM: `2**69/B` where B is max blocks encrypted by a key. Meaning
+    `2**59` for 1KB, `2**49` for 1MB, `2**39` for 1GB
+  - Salsa, ChaCha, XSalsa, XChaCha: `2**100`
+
+##### AES internals and block modes
+
+`cipher = encrypt(block, key)`. Data is split into 128-bit blocks. Encrypted in 10/12/14 rounds (128/192/256bit). Every round does:
+
+1. **S-box**, table substitution
+2. **Shift rows**, cyclic shift left of all rows of data array
+3. **Mix columns**, multiplying every column by fixed polynomial
+4. **Add round key**, round_key xor i-th column of array
+
+For non-deterministic (not ECB) schemes, initialization vector (IV) is mixed to block/key;
+and each new round either depends on previous block's key, or on some counter.
+
+- ECB — simple deterministic replacement. Dangerous: always map x to y. See [AES Penguin](https://words.filippo.io/the-ecb-penguin/)
+- CBC — key is previous round’s block. Hard to use: need proper padding, also needs MAC
+- CTR — counter, allows to create streaming cipher. Requires good IV. Parallelizable. OK, but no MAC
+- GCM — modern CTR, parallel, with MAC
+- SIV — synthetic initialization vector, nonce-misuse-resistant. Guarantees that, when a nonce is repeated,
+  the only security loss is that identical plaintexts will produce identical ciphertexts.
+- XTS — used in hard drives. Similar to ECB (deterministic), but has `[i][j]`
+  tweak arguments corresponding to sector i and 16-byte block (part of sector) j. Not authenticated!
+
+GCM / SIV are not ideal:
+
+- Conservative key wear-out is `2**32` (4B) msgs
+- MAC can be forged: see Poly1305 section above. Same for SIV
+
+## Security
+
+The library has not been independently audited yet.
+
+It is tested against property-based, cross-library and Wycheproof vectors,
+and has fuzzing by [Guido Vranken's cryptofuzz](https://github.com/guidovranken/cryptofuzz).
+
+If you see anything unusual: investigate and report.
+
+### Constant-timeness
+
+_JIT-compiler_ and _Garbage Collector_ make "constant time" extremely hard to
+achieve [timing attack](https://en.wikipedia.org/wiki/Timing_attack) resistance
+in a scripting language. Which means _any other JS library can't have
+constant-timeness_. Even statically typed Rust, a language without GC,
+[makes it harder to achieve constant-time](https://www.chosenplaintext.ca/open-source/rust-timing-shield/security)
+for some cases. If your goal is absolute security, don't use any JS lib — including bindings to native ones.
+Use low-level libraries & languages. Nonetheless we're targetting algorithmic constant time.
+
+AES uses T-tables, which means it can't be done in constant-time in JS.
+
+### Supply chain security
+
+- **Commits** are signed with PGP keys, to prevent forgery. Make sure to verify commit signatures.
+- **Releases** are transparent and built on GitHub CI. Make sure to verify [provenance](https://docs.npmjs.com/generating-provenance-statements) logs
+- **Rare releasing** is followed to ensure less re-audit need for end-users
+- **Dependencies** are minimized and locked-down:
+  - If your app has 500 dependencies, any dep could get hacked and you'll be downloading
+    malware with every install. We make sure to use as few dependencies as possible
+  - We prevent automatic dependency updates by locking-down version ranges. Every update is checked with `npm-diff`
+- **Dev Dependencies** are only used if you want to contribute to the repo. They are disabled for end-users:
+  - scure-base, micro-bmark and micro-should are developed by the same author and follow identical security practices
+  - prettier (linter), fast-check (property-based testing) and typescript are used for code quality, vector generation and ts compilation. The packages are big, which makes it hard to audit their source code thoroughly and fully
+
+### Randomness
+
+We're deferring to built-in
+[crypto.getRandomValues](https://developer.mozilla.org/en-US/docs/Web/API/Crypto/getRandomValues)
+which is considered cryptographically secure (CSPRNG).
+
+In the past, browsers had bugs that made it weak: it may happen again.
+Implementing a userspace CSPRNG to get resilient to the weakness
+is even worse: there is no reliable userspace source of quality entropy.
+
+## Speed
+
+To summarize, noble is the fastest JS implementation of Salsa, ChaCha and AES.
+
+You can gain additional speed-up and
+avoid memory allocations by passing `output`
+uint8array into encrypt / decrypt methods.

+## Upgrading
+
+Upgrade from `micro-aes-gcm` package is simple:
+
+```js
+// prepare
+const key = Uint8Array.from([
+  64, 196, 127, 247, 172, 2, 34, 159, 6, 241, 30, 174, 183, 229, 41, 114, 253, 122, 119, 168, 177,
+  243, 155, 236, 164, 159, 98, 72, 162, 243, 224, 195,
+]);
+const message = 'Hello world';
+
+// previous
+import * as aes from 'micro-aes-gcm';
+const ciphertext = await aes.encrypt(key, aes.utils.utf8ToBytes(message));
+const plaintext = await aes.decrypt(key, ciphertext);
+console.log(aes.utils.bytesToUtf8(plaintext) === message);
+
+// became =>
+
+import { gcm } from '@noble/ciphers/aes';
+import { bytesToUtf8, utf8ToBytes } from '@noble/ciphers/utils';
+import { managedNonce } from '@noble/ciphers/webcrypto';
+const aes = managedNonce(gcm)(key);
+const ciphertext = aes.encrypt(utf8ToBytes(message));
+const plaintext = aes.decrypt(key, ciphertext);
+console.log(bytesToUtf8(plaintext) === message);

+RFC8439 requires multi-step cipher stream, where
+authKey starts with counter: 0, actual msg with counter: 1.
+
+For this, we need a way to re-use nonce / counter:
+
+    const counter = new Uint8Array(4);
+    chacha(..., counter, ...); // counter is now 1
+    chacha(..., counter, ...); // counter is now 2
+
+This is complicated:
+
+- 32-bit counters are enough, no need for 64-bit: max ArrayBuffer size in JS is 4GB
+- Original papers don't allow mutating counters
+- Counter overflow is undefined [^1]
+- Idea A: allow providing (nonce | counter) instead of just nonce, re-use it
+- Caveat: Cannot be re-used through all cases:
+- * chacha has (counter | nonce)
+- * xchacha has (nonce16 | counter | nonce16)
+- Idea B: separate nonce / counter and provide separate API for counter re-use
+- Caveat: there are different counter sizes depending on an algorithm.
+- salsa & chacha also differ in structures of key & sigma:
+  salsa20:      s[0] | k(4) | s[1] | nonce(2) | ctr(2) | s[2] | k(4) | s[3]
+  chacha:       s(4) | k(8) | ctr(1) | nonce(3)
+  chacha20orig: s(4) | k(8) | ctr(2) | nonce(2)
+- Idea C: helper method such as `setSalsaState(key, nonce, sigma, data)`
+- Caveat: we can't re-use counter array
+
+xchacha [^2] uses the subkey and remaining 8 byte nonce with ChaCha20 as normal
+(prefixed by 4 NUL bytes, since [RFC8439] specifies a 12-byte nonce).

+RFC8439 requires multi-step cipher stream, where
+authKey starts with counter: 0, actual msg with counter: 1.
+
+For this, we need a way to re-use nonce / counter:
+
+    const counter = new Uint8Array(4);
+    chacha(..., counter, ...); // counter is now 1
+    chacha(..., counter, ...); // counter is now 2
+
+This is complicated:
+
+- 32-bit counters are enough, no need for 64-bit: max ArrayBuffer size in JS is 4GB
+- Original papers don't allow mutating counters
+- Counter overflow is undefined [^1]
+- Idea A: allow providing (nonce | counter) instead of just nonce, re-use it
+- Caveat: Cannot be re-used through all cases:
+- * chacha has (counter | nonce)
+- * xchacha has (nonce16 | counter | nonce16)
+- Idea B: separate nonce / counter and provide separate API for counter re-use
+- Caveat: there are different counter sizes depending on an algorithm.
+- salsa & chacha also differ in structures of key & sigma:
+  salsa20:      s[0] | k(4) | s[1] | nonce(2) | ctr(2) | s[2] | k(4) | s[3]
+  chacha:       s(4) | k(8) | ctr(1) | nonce(3)
+  chacha20orig: s(4) | k(8) | ctr(2) | nonce(2)
+- Idea C: helper method such as `setSalsaState(key, nonce, sigma, data)`
+- Caveat: we can't re-use counter array
+
+xchacha [^2] uses the subkey and remaining 8 byte nonce with ChaCha20 as normal
+(prefixed by 4 NUL bytes, since [RFC8439] specifies a 12-byte nonce).
