RNCryptorHeader

Fields

rncVersion :: !Word8: Data format version. Currently 3.
rncOptions :: !Word8: bit 0 - uses password
rncEncryptionSalt :: !ByteString: iff option includes "uses password"
rncHMACSalt :: !ByteString: iff options includes "uses password"
rncIV :: !ByteString: The initialisation vector The ciphertext is variable and encrypted in CBC mode
rncHMAC :: ByteString -> ByteString: The HMAC (32 bytes). This field is a continuation as the HMAC is at the end of the file.

newRNCryptorContext :: ByteString -> RNCryptorHeader -> RNCryptorContext Source

newRNCryptorHeader :: ByteString -> IO RNCryptorHeader Source

Generates a new RNCryptorHeader, suitable for encryption.

renderRNCryptorHeader :: RNCryptorHeader -> ByteString Source

Concatenates this RNCryptorHeader into a raw sequence of bytes, up to the IV. This means you need to append the ciphertext plus the HMAC to finalise the encrypted file.
