Functions

func AESDecryptLocal

func AESDecryptLocal(encrypted []byte, localKey []byte, msgKey []byte) (decrypted []byte, err error)

func CreateLocalKey

func CreateLocalKey(pass []byte, salt []byte) []byte

CreateLocalKey creates the key used by DecryptLocal. The default password is empty.

func CreateLocalLegacyKey

func CreateLocalLegacyKey(pass []byte, salt []byte) []byte

CreateLocalLegacyKey creates the key used by DecryptLocal. Legacy must use for settings.

func DecryptLocal

func DecryptLocal(encryptedMsg []byte, localKey []byte) (decrypted []byte, err error)

DecryptLocal decrypts a message. localKey should be created at CreateLocalKey.

func PrepareAESoldmtp

func PrepareAESoldmtp(localKey []byte, msgKey []byte) (key []byte, iv []byte)

PrepareAESoldmtp produces key and iv, using localKey and msgKey. localKey comes from CreateLocalKey, msgKey are the first 16 bytes from encrypted message.
