NOSTR Core Library - Cleanup Report

Overview

After successfully resolving the NIP-04 ECDH compatibility issues, we performed a comprehensive cleanup of debugging artifacts and temporary files created during the troubleshooting process.

Files Moved to Trash/debug_tests/

NIP-04 Debug Tests (Created During Troubleshooting)

  • aes_debug_test.c/.exe - AES encryption debugging
  • ecdh_debug_test.c/.exe - ECDH shared secret debugging
  • ecdh_x_coordinate_test.c/.exe - X coordinate extraction testing
  • ecdh_comprehensive_debug_test.c/.exe - Comprehensive ECDH testing
  • nip04_decrypt_debug_test.c/.exe - Decryption specific debugging
  • nip04_detailed_debug_test.c/.exe - Detailed step-by-step debugging
  • nip04_ecdh_debug_test.c/.exe - NIP-04 ECDH specific testing
  • nip04_encrypt_only_test.c/.exe - Encryption-only testing
  • nip04_minimal_test.c/.exe - Minimal test cases
  • nip04_simple_test.c/.exe - Simple test implementation
  • nip04_step_by_step_debug_test.c/.exe - Step-by-step debugging
  • decrypt_debug_minimal.c/.exe - Minimal decryption debugging
  • noble_vs_libsecp_comparison.c/.exe - JavaScript comparison testing

Other Debug Files

  • debug_bip32.c/.exe - BIP32 debugging
  • debug_bip32_test.c/.exe - BIP32 test debugging
  • frame_debug_test.c/.exe - Frame debugging
  • debug.log - 9.8GB debug log file (major space savings!)

JavaScript Reference Implementation

  • nostr-tools/ - JavaScript reference implementation used for comparison
    • nip04.ts - TypeScript NIP-04 implementation
    • debug_nip04.js - JavaScript debugging script

Files Kept (Essential Tests)

Core Functionality Tests

  • nip04_test.c - Main comprehensive NIP-04 test (our final working test)
  • simple_init_test.c - Basic library initialization test
  • nostr_crypto_test.c - Cryptographic functions test
  • nostr_test_bip32.c - BIP32 HD wallet test
  • relay_pool_test.c - Relay pool functionality test
  • sync_test.c - Synchronization test
  • test_pow_loop.c - Proof of work test

Build Infrastructure

  • Makefile - Test compilation rules
  • build.tests.sh - Test build script

Key Improvements Made

1. Function Naming Clarity

  • Added nostr_schnorr_sign() - clearly indicates BIP-340 Schnorr signatures
  • Maintained nostr_ec_sign() as legacy wrapper for backward compatibility
  • Benefit: Prevents future confusion between ECDH and signature operations

2. ECDH Compatibility Fix

  • Fixed ECDH implementation to match NIP-04 specification exactly
  • Custom hash function that extracts only X coordinate (no hashing)
  • Result: 100% compatible with JavaScript NOSTR ecosystem

3. Memory Management

  • Fixed buffer overflow issues in NIP-04 decryption
  • Proper base64 buffer size calculations
  • Enhanced error handling and cleanup
  • Result: No more segmentation faults

Final Test Status

✅ nip04_test: PASS (Round-trip + Reference compatibility)
✅ Memory management: Fixed (No segfaults)  
✅ ECDH compatibility: 100% JavaScript ecosystem compatible
✅ Function naming: Clear and unambiguous

Space Savings

  • Removed 9.8GB debug.log file
  • Cleaned up 20+ debugging test files and executables
  • Organized debugging artifacts in Trash/debug_tests/ for easy reference

Secp256k1 Status

  • Checked for extra debugging code: CLEAN
  • All files are standard libsecp256k1 build artifacts
  • No cleanup needed

The NOSTR core library is now in a clean, production-ready state with fully functional NIP-04 encryption/decryption that's compatible with the broader NOSTR ecosystem!
