In swift, strings must be strictly utf8, and when golang
returns a string with non utf8 characters, it gets translated to
an empty string for utf8.
To avoid this situation, we sanitize strings before returning them.
This behavior is only enabled when building with the "ios" build tag.
When the PGP/MIME decryption encounters a signature verification error, it will keep decrypting the content
and return it in the appropriate callbacks.
This allows the caller to choose to display the content with a warning rather than just returning an error.
In pgpMessage.SeparateKeyAndData(), the parsing would
ignore AEAD encrypted data packets. Which would result
in a split message with a nil data packet.
We add support for AEAD encrypted data packets.
This also affects `NewPGPSplitMessageFromArmored` and `NewPGPSplitMessage`.
When decrypting message, we have to use verifyTime in the config
otherwise signatures not valid at verifyTime but valid at Now()
will be seen as valid.
Because a GNU dummy key has a `PrivateKey` property, the existing check will
count it as a key to be decrypted. However, a `Decrypt` call on such key will
then yield an error, as it is a dummy key.
This commit addresses this behaviour by summing all valid decrpytable private
keys and returning on their count.
Further, it adapts `Unlock` to ignore any dummy subkey.
