a-sit-plus/signum 3.1.0

on GitHub

Fixes

• Standardize class names: Ec -> EC everywhere
• Fix an edge case where very small r/s in CryptoSignature.EC would be corrupted
• Remove bogus ASN.1 encoding from JWS Algorithms
  • CryptoSignature.EC now requires specification of a curve or size when reading raw bytes

Features

• Support ASN.1 encoding/decoding for BigInteger
• Expose generator, order and cofactor of ECCurve
• Extend list of values in JweAlgorithm and JweEncryption
• Extend properties in JweHeader
• Extend properties in JwsHeader
• BREAKING CHANGE: Completely revamp the ASN.1 builder DSL
  • explicitly require + to add some ASN.1 element to a builder
  • Make convenience functions like Bool(<boolean value>)work stand-alone
• Introduce common interface JsonWebAlgorithm for Jw{s,e}Algorithm
• JsonWebKey Changes:
  • do not generate kid when there is none and allow removing it
  • reference JsonWebAlgorithm instead of JwsAlgorithm
  • add .didEncoded, which may return null, if encoding fails
• add .curve to EC CryptoAlgorithms
• Change JweAlgorithm to sealed class to support unknown algorithms
• Add generic ECPoint class
• Implement elliptic-curve arithmetic
