Release version 2.6.0

Added

• API for adding context to detached signatures:

   sig, err := keyRing.SignDetachedWithContext(message, context)

• API to verify the context of detached signatures:

   err := keyRing.VerifyDetachedWithContext(message, signature, verifyTime, verificationContext)

Changed

• Update github.com/ProtonMail/go-crypto to the latest version
• More strictly verify detached signatures: reject detached signatures from revoked and expired keys.
• In GetVerifiedSignatureTimestamp, use the new VerifyDetachedSignatureAndHash function to get the verified signature, instead of parsing the signature packets manually to get the timestamp.
• Upgraded golang.org/x/crypto dependency to v0.7.0

Release version 2.5.2

Changed

• Update github.com/ProtonMail/go-crypto to the latest version

Release version 2.5.1

Added

• Streaming API to encrypt with compression:
  • func (keyRing *KeyRing) EncryptStreamWithCompression
  • func (keyRing *KeyRing) EncryptSplitStreamWithCompression
  • func (sk *SessionKey) EncryptStreamWithCompression

Release version 2.5.0

Changed

• Update github.com/ProtonMail/go-crypto to the latest version
• Update github.com/ProtonMail/go-mime to the latest version, which cleans up unneeded dependencies. And fix an issue with PGP/MIME messages with non standard encodings.
• Sanitize strings returned in MIMECallbacks.OnBody() and PlainMessage.GetString(). Strings that have non utf8 characters will be sanitized to have the "character unknown" character : � instead.
• Detached sign text messages with signature type text. Similarly, clearsigned messages now also use signature type text.
• Leave trailing spaces of text messages intact (except for clearsigned messages, where the spec requires us to trim trailing spaces). Note that for backwards compatibility, when verifying detached signatures over text messages, the application will have to trim trailing spaces in order for the signature to verify, if it was created by a previous version of this library (using crypto.NewPlainMessageFromString()).

Release version 2.4.10

Update go-crypto

Release version 2.4.9

Upgrade underlying go-crypto version

Release version 2.4.8

Add AEAD decryption support

Release version 2.4.7

• DecryptMIMEMessage will return the decrypted content in the OnBody callback, even when there's a signature verification error. That lets the caller decide whether they want to use the content with a warning or hard fail on signature errors.
• Key generation functions no longer return an error if either the name or email is empty

Release version 2.4.6

Fix MIME signature parsing issues

Release version 2.4.5

Deprecate SeparateKeyAndData, replace with (msg *PGPMessage) SplitMessage() to split PGP messages
