- Encode EC coordinates and private d with curve-width (32/48/66 bytes) to satisfy RFC 7518, preserving leading zero octets. - Restrict JWK values to registered JOSE names: P-256, P-384, P-521, secp256k1. Raise ValueError for unregistered curves (P-192, P-224, Brainpool). - Add regression tests: deterministic coordinate/private-value widths, leading-zero preservation, supported curve names, and rejection of unsupported curves. - Mypy clean; all core and backend tests pass.
kca-core
Pure, I/O-free PKI domain logic for KCA. It knows how to generate and parse keys, build distinguished names, encode X.509 extensions, issue certificates, create CSRs and CRLs, apply templates, and convert every supported import and export format. It has no kaya, database or filesystem dependencies and is unit-tested in isolation.
