• Note: We are deprecating and will soon be removing the debug-only serialization for cryptographic datatypes like certificates, public keys, etc.
  • We support robust ASN.1 encoding and mapping from/to JOSE and COSE datatypes and our ASN.1 structures support pretty printing.
  • -> There is no need for this misleading serialization support for debugging anymore
  • @Serializable suggests deserialization from JSON, CBOR, etc. works, which was never universally true
  • Getting native ASN.1 serialization for kotlinx-serialization is now a no-brainer given we support every primitive required.
  • This note will be prepended to the changelog entries until the @Serialization annotations have been removed.
    • This will happen by Indispensable 4.0.0 / Supreme 1.0.0, if not before then.
• Introduce support for ASN.1 REAL
• Add built-in ASN.1 ENUMERATED support
• Rename ObjectIdentifier.parse -> ObjectIdentifier.decodeFromAsn1ContentBytes in accordance with other similar functions
• Update data classes for Wallet Attestation from OpenID4VC HAIP and OpenID4VCI:
  • Deprecate authenticationLevel (aal) in JsonWebToken, removed from standards
  • Deprecate key_type, user_authentication in ConfirmationClaim, removed from standards
  • Deprecate types WalletAttestationUserAuthentication, WalletAttestationKeyType, removed from standards
  • Add wallet_name, wallet_link, status to JsonWebToken, used in Key Attestation JWT
  • Add KeyAttestationJwt from OpenID4VCI
• Add dedicated Android targets (SDK 30 / JDK 1.8) to all modules
• Fix internal deprecations
• Raise deprecation level to ERROR for deprecated functions:
  • Asn1Element.Companion.parseAll
  • Asn1Element.Companion.parse
  • Asn1Element.Companion.decodeFromDerHexString
  • Asn1Element.asPrimitiveOctetString
  • CryptoPublicKey.fromJcaPublicKey
  • CryptoPublicKey.RSA.fromJcaPublicKey
  • CryptoPublicKey.EC.fromJcaPublicKey
  • CryptoSignature.invoke
  • CryptoPublicKey.RSA(n: ByteArray, e: ByteArray)
  • CryptoPublicKey.EC(curve: ECCurve, x: ByteArray, usePositiveY: Boolean)
  • CryptoPublicKey.EC(curve: ECCurve, x: ByteArray, y: ByteArray)
  • ECCurve.keyLengthBits
  • ECCurve.coordinateLengthBytes
  • ECCurve.signatureLengthBytes
