cardano-signer 1.12.0

• Release-Notes for 1.12.0

  General:

  • The output via --json-extended is now showing more details about the address (hex, type, network)
  • The help description can now be displayed for each sub command like: cardano-signer sign --cip8 --help
  • Addresses provided via the --address parameter can now be a bech-address, hex-string or the path to a file containing the bech-address (typical mywallet.addr) files

  CIP-8 / CIP-30 updates:

  • Completely reworked CIP-8/CIP-30 code. Flags --cip8 & --cip30 will currently do the same, because CIP-30 uses CIP-8 signing.
  • Signing a payload now generates a full COSE_Sign1 signature together with the COSE_Key publicKey
  • The payload can be set to hashed via the new flag --hashed
  • The payload can be excluded from the COSE_Sign1 signature with the new flag --nopayload
  • The signing address will be automatically checked against the publicKey (signing and verification)
  • Extended data structure check of the given COSE_Sign1 & COSE_Key
  • Verification can be done against the COSE_Sign1 & COSE_Key, and optionally also against a given payload and address
  • The output via --json-extended shows additional information if the payload is hashed, address infos, etc.
