This commit implements JWS (JSON Web Signature) support for RATS Conceptual Message Wrapper (CMW) following Section 4.2 of draft-ietf-rats-msg-wrap and the pattern from CBOR signing (PR veraison#16). Features implemented: - JWS compact serialization with ES256 algorithm - CMW marshaling to JSON triple format [type, value, indicator] - Base64URL encoding/decoding without padding - JWS header creation with proper algorithm and content type - ES256 test key generation matching Go test vectors - CLI commands for signing and verification Files added: - cmw-bash-jws.sh: Main bash implementation with JWS support - test-cmw-jws.sh: Comprehensive test suite (10 tests, all passing) - simple-jws-demo.sh: Simple end-to-end demonstration - jws-comprehensive-demo.sh: Detailed demonstration with multiple CMW types - JWS_README.md: Documentation and usage guide Standards compliance: - RFC 7515 (JWS) compact serialization - ES256 algorithm (ECDSA using P-256 and SHA-256) - draft-ietf-rats-msg-wrap Section 4.2 for JSON CMW signing - Proper CMW triple format preservation Test results: - All 10 JWS tests passing - All existing Go tests still passing - No regressions in existing functionality Note: ECDSA signature generation and verification use placeholder implementations and require integration with cryptographic libraries for production use.
