OpenSSL.EVP.Cipher

Description

An interface to symmetric cipher algorithms.

Synopsis

Documentation

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

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

getCipherNames returns a list of name of symmetric cipher algorithms.

CryptoMode represents instruction to cipher and such like.

Constructors

Encrypt
Decrypt

Arguments

:: 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.

Arguments

:: Cipher	algorithm to use
-> ByteString	symmetric key
-> ByteString	IV
-> CryptoMode	operation
-> ByteString	input string to encrypt/decrypt
-> IO ByteString	the result string

cipherBS strictly encrypts or decrypts a chunk of data.

Arguments

:: Cipher	algorithm to use
-> ByteString	symmetric key
-> ByteString	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.

Arguments

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