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
:: k | |
-> ByteString | |
-> ByteString | encrypt data of size |
:: k | |
-> ByteString | |
-> ByteString | decrypt data of size |
:: ByteString | |
-> Maybe k | smart constructor for keys from a bytestring. |

Cipher block chaining encryption for lazy bytestrings
unCbcLazy :: k -> IV k -> ByteString -> (ByteString, IV k)
Cipher block chaining decryption for lazy bytestrings
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.
unSiv :: k -> k -> [ByteString] -> ByteString -> Maybe ByteString
SIV (Synthetic IV) 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 authentication fails.
ecbLazy :: k -> ByteString -> ByteString
Cook book mode - not really a mode at all. If you don't know what you're doing, don't use this mode^H^H^H^H library.
unEcbLazy :: k -> ByteString -> ByteString
ECB decrypt, complementary to ecb
.
cfbLazy :: k -> IV k -> ByteString -> (ByteString, IV k)
Ciphertext feed-back encryption mode for lazy bytestrings (with s == blockSize)
unCfbLazy :: k -> IV k -> ByteString -> (ByteString, IV k)
Ciphertext feed-back decryption mode for lazy bytestrings (with s == blockSize)
ofbLazy :: k -> IV k -> ByteString -> (ByteString, IV k)
Output feedback mode for lazy bytestrings
unOfbLazy :: k -> IV k -> ByteString -> (ByteString, IV k)
Output feedback mode for lazy bytestrings
buildKeyIO :: BlockCipher k => IO k
Build a symmetric key using the system entropy (see Random
)
zeroIV :: BlockCipher k => IV k
Obtain an IV
made only of zeroes
