PGPainless Changelog

1.2.0

  • Improve exception hierarchy for key-related exceptions
    • See PR for more information on how to migrate.
  • Bump Bouncy Castle to 1.71
    • Switch from bcpg-jdk15on:1.70 to bcpg-jdk15to18:1.71
    • Switch from bcprov-jdk15on:1.70 to bcprov-jdk15to18:1.71
  • Implement merging of certificate copies
    • can be used to implement updating certificates from key servers
  • Fix KeyRingUtils.keysPlusPublicKey()
  • Add support for adding PolicyURI and RegularExpression signature subpackets on signatures

1.1.5

  • SOP encrypt: match signature type when using encrypt --as= option
  • ProducerOptions.setEncoding(): The encoding is henceforth only considered metadata and will no longer trigger CRLF encoding.
    • This fixes broken signature generation for mismatching (StreamEncoding,DocumentSignatureType) tuples.
    • Applications that rely on CRLF-encoding can request PGPainless to apply this encoding by calling ProducerOptions.applyCRLFEncoding(true).
  • Rename KeyRingUtils.removeSecretKey() to stripSecretKey().
  • Add handy SignatureOptions.addSignature() method.
  • Fix ClassCastException when evaluating a certificate with third party signatures. Thanks @p-barabas for the initial report and bug fix!

1.1.4

  • Add utility method KeyRingUtils.removeSecretKey() to remove secret key part from key ring
    • This can come in handy when using primary keys stored offline
  • Add EncryptionResult.isEncryptedFor(certificate)
  • ArmorUtils.toAsciiArmoredString() methods now print out primary user-id and brief information about further user-ids (thanks @bratkartoffel for the patch)
  • Methods of KeyRingUtils and ArmorUtils classes are now annotated with @Nonnull/@Nullable
  • Enums fromId(code) methods are now annotated with @Nullable and there are now requireFromId(code) counterparts which are @Nonnull.
  • ProducerOptions.setForYourEyesOnly() is now deprecated (reason is deprecation in the
  • crypto-refresh-05 document)
  • Add SessionKey.toString()
  • Partially fix generation of malformed signature packets when using different combinations of StreamEncoding and DocumentSignatureType values
    • Unfortunately PGPainless still produces broken signatures when using either StreamEncoding.TEXT or StreamEncoding.UTF8 in combination with DocumentSignatureType.BINARY_DOCUMENT.
  • Deprecate ProducerOptions.setEncoding(StreamEncoding)
    • Will be removed in a future release
  • Remove StreamEncoding.MIME (was removed from the standard)

1.1.3

  • Make SigningOptions.getSigningMethods() part of internal API
  • Fix crash when trying to do verification of unmatched SignersUserId signature subpacket

    • Revocation Reason: critical -> non-critical
