Rescued from uncommitted work in sovereign_browser/nostr_core_lib:
- nostr_signer_derive_hmac(): deterministic MAC over caller data using the
signer's secp256k1 private key. Local backend computes HMAC-SHA256 directly;
remote nsigner backend calls the 'derive' verb (algorithm:'secp256k1').
- nsigner_transport_list_serial(): enumerate /dev/ttyUSB* (FTDI/CH340/CP210x/
PL2303 USB-serial adapters) in addition to /dev/ttyACM* CDC-ACM devices.
- tests/nsigner_client_test.c: local derive_hmac reference-match test.
- Added NIP-42 authentication implementation (nip042.c, nip042.h)
- Added NIP-42 test suite (nip42_test.c, nip42_test)
- Updated common core files for NIP-42 support
- Updated build script
- Rebuilt test binaries
BREAKING CHANGE: Library now requires system-installed dependencies
Major Changes:
- Convert secp256k1 from bundled static lib to system dependency
- Convert OpenSSL from bundled static lib to system dependency
- Convert curl from bundled static lib to system dependency
- Update build.sh with pkg-config detection and fallback logic
- Remove all static library extraction/building logic
- Update README.md with new dependency requirements and installation
Build System:
- Add detect_system_secp256k1() with pkg-config support
- Add detect_system_openssl() with pkg-config support
- Add detect_system_curl() with pkg-config support
- Remove secp256k1 building/extraction from ar archive
- Update CFLAGS and LIBS to use system library variables
- Clear error messages for missing dependencies with install commands
Documentation:
- Add system dependency installation for Ubuntu/Debian/CentOS/macOS
- Update all compile/link examples to include -lssl -lcrypto -lcurl -lsecp256k1
- Remove references to 'self-contained' and 'no external dependencies'
- Update integration examples throughout README
Benefits:
- Smaller library size (only internal code bundled)
- Automatic security updates via system package manager
- Standard Linux library distribution pattern
- Reduced build complexity
- Better system integration with pkg-config
Required Installation:
Ubuntu/Debian: sudo apt install libssl-dev libcurl4-openssl-dev libsecp256k1-dev
CentOS/RHEL: sudo yum install openssl-devel libcurl-devel libsecp256k1-devel
macOS: brew install openssl curl secp256k1
- Moved old tests from tests/old/ to main tests/ directory
- Renamed nostr_test_bip32.c to bip32_test.c for consistency
- Renamed nostr_crypto_test.c to crypto_test.c for consistency
- Renamed wss_test.c and moved from old directory
- Fixed unused variable warning in bip32_test.c
- Updated build system and workspace rules
- Cleaned up old compiled test executables
- Updated nostr_common.h and core_relays.c
- Removed obsolete nostr_core.h.old backup file
This consolidates all active tests into the main directory and removes
outdated test files while maintaining a clean, organized structure.
- Complete C library template with OpenSSL-based crypto
- Comprehensive build system (Makefile, build.sh)
- Example code and test suite
- Documentation and usage guides
- Cross-platform compatibility (x64/ARM64)
- Production-ready structure for C library projects
