Documentation

data Cipher Source

Cipher is an opaque object that represents an algorithm of symmetric cipher.

getCipherByName :: String -> IO (Maybe Cipher) Source

getCipherByName name returns a symmetric cipher algorithm whose name is name. If no algorithms are found, the result is Nothing.

getCipherNames :: IO [String] Source

getCipherNames returns a list of name of symmetric cipher algorithms.

data CryptoMode Source

CryptoMode represents instruction to cipher and such like. Constructors Encrypt Decrypt

cipher Source

:: Cipher algorithm to use -> String symmetric key -> String IV -> CryptoMode operation -> String An input string to encrypt/decrypt. Note that the string must not contain any letters which aren't in the range of U+0000 - U+00FF. -> IO String the result string cipher lazilly encrypts or decrypts a stream of data. The input string doesn't necessarily have to be finite.

cipherBS Source

:: Cipher algorithm to use -> String symmetric key -> String IV -> CryptoMode operation -> ByteString input string to encrypt/decrypt -> IO ByteString the result string cipherBS strictly encrypts or decrypts a chunk of data.

cipherLBS Source

:: Cipher algorithm to use -> String symmetric key -> String IV -> CryptoMode operation -> ByteString input string to encrypt/decrypt -> IO ByteString the result string cipherLBS lazilly encrypts or decrypts a stream of data. The input string doesn't necessarily have to be finite.
