Description

mutable and unsafe interface for Block ciphers. export a BlockCipherIO class

Synopsis

class BlockCipher cipher => BlockCipherIO cipher where
- ecbEncryptMutable :: cipher -> PtrDest -> PtrSource -> BufferLength -> IO ()
- ecbDecryptMutable :: cipher -> PtrDest -> PtrSource -> BufferLength -> IO ()
- cbcEncryptMutable :: cipher -> PtrIV -> PtrDest -> PtrSource -> BufferLength -> IO ()
- cbcDecryptMutable :: cipher -> PtrIV -> PtrDest -> PtrSource -> BufferLength -> IO ()
type BufferLength = Word32
type PtrDest = Ptr Word8
type PtrSource = Ptr Word8
type PtrIV = Ptr Word8
onBlock :: BlockCipherIO cipher => cipher -> (ByteString -> ByteString) -> PtrDest -> PtrSource -> BufferLength -> IO ()
