OpenSSL.EVP.Cipher

An interface to symmetric cipher algorithms.

newtypenewtype Cipher

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

valuegetCipherByName :: String -> IO (Maybe Cipher)

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

valuegetCipherNames :: IO [String]

getCipherNames returns a list of name of symmetric cipher algorithms.

datadata CryptoMode

CryptoMode represents instruction to cipher and such like.

valuecipher

:: 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

Deprecated. Use cipherBS, cipherLBS or cipherStrictLBS.

cipher lazilly encrypts or decrypts a stream of data. The input string doesn't necessarily have to be finite.

valuecipherBS

cipherBS strictly encrypts or decrypts a chunk of data.

valuecipherLBS

cipherLBS lazilly encrypts or decrypts a stream of data. The input string doesn't necessarily have to be finite.

valuecipherStrictLBS

Encrypt a lazy bytestring in a strict manner. Does not leak the keys.
