data RNCryptorHeader

Constructors

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.

data RNCryptorContext

newRNCryptorContext :: ByteString -> RNCryptorHeader -> RNCryptorContext

newRNCryptorHeader :: ByteString -> IO RNCryptorHeader

Generates a new RNCryptorHeader, suitable for encryption.

renderRNCryptorHeader :: RNCryptorHeader -> ByteString

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.

blockSize :: Int
