class Serialize k => BlockCipher k where #
The BlockCipher class is intended as the generic interface targeted by maintainers of Haskell cipher implementations.
Minimum complete definition: blockSize, encryptBlock, decryptBlock, buildKey, and keyLength.
Instances must handle unaligned data

sivLazy :: k -> k -> [ByteString] -> ByteString -> Maybe ByteString #
SIV (Synthetic IV) mode for lazy bytestrings. The third argument is the optional list of bytestrings to be authenticated but not encrypted As required by the specification this algorithm may return nothing when certain constraints aren't met.
unSivLazy :: k -> k -> [ByteString] -> ByteString -> Maybe ByteString #
SIV (Synthetic IV) for lazy bytestrings. The third argument is the optional list of bytestrings to be authenticated but not encrypted. As required by the specification this algorithm may return nothing when authentication fails.
siv :: k -> k -> [ByteString] -> ByteString -> Maybe ByteString #
SIV (Synthetic IV) mode for strict bytestrings. First argument is the optional list of bytestrings to be authenticated but not encrypted. As required by the specification this algorithm may return nothing when certain constraints aren't met.
