Release version 2.3.0

Added Key.IsRevoked() to check the revocation status of a key and upgraded underlying crypto library to fix handling of revoked keys

Release version 2.2.5

The global pgp variable fields is now protected with a lock and dummy keys are locked and unlocked correctly

Release version 2.2.4

Fixed

• Use the provided verifyTime instead of the current time when verifying embedded signatures.

Release version 2.2.3

Changed

• Keys are now generated with ZLIB as optional compression algorithm
• Upgraded underlying crypto library

Release version 2.2.2

Added

• NewKeyFromEntity to create a key from an openpgp entity

Changed

• Improved documentation for differences between text and binary messages

Deprecated

• (key *Key) Check() (bool, error) is now deprecated, all keys are now checked upon import from x/crypto

Fixed

• Dummy keys now show the correct locked/unlocked status

Security

• All keys are now checked on parsing from the underlying library

v2.2.1: Merge pull request #140 from ProtonMail/release-2.2.1

Changed

• Changed the returned SignatureVerificationError.Status when trying to verify a message with no embedded signature. It used to return constants.SIGNATURE_NO_VERIFIER and now returns constants.SIGNATURE_NOT_SIGNED.
  This change impacts :
  • func (sk *SessionKey) DecryptAndVerify(...)
  • func (msg *PlainMessageReader) VerifySignature(...)
  • func (keyRing *KeyRing) Decrypt(...)
• Improved error messages for failures in password protected message decryption

Added

• Helper to access the SignatureVerificationError explicitly when decrypting streams in mobile apps:

   func VerifySignatureExplicit(
   	reader *crypto.PlainMessageReader,
   ) (signatureVerificationError *crypto.SignatureVerificationError, err error)

Release version 2.2.0

Add streaming API

Release version 2.1.10

Removed time interpolation via monotonic clock that can cause signatures in the future

Release version 2.1.9

Upgrade the underlying go-crypto forking off from x/crypto, remove duplicate modules.

Release version 2.1.8

Added:

• Key and KeyRing methods to check if a key/keyring can Encrypt or Verify

(key *Key) CanVerify() bool
(key *Key) CanEncrypt() bool
(keyRing *KeyRing) CanVerify() bool
(keyRing *KeyRing) CanEncrypt() bool

• SessionKey methods to encrypt/decrypt and simultaneously sign/verify with an asymmetric key (embedded signature)

(sk *SessionKey) EncryptAndSign(message *PlainMessage, signKeyRing *KeyRing) ([]byte, error)
(sk *SessionKey) DecryptAndVerify(dataPacket []byte, verifyKeyRing *KeyRing, verifyTime int64) (*PlainMessage, error)

• The mobile helper DecryptSessionKeyExplicitVerify to allow using session key decryption + verification operations via gomobile
