Symmetric block cipher class, mutable API
Minimal complete definition
Methods
ecbEncryptMutable :: cipher -> PtrDest -> PtrSource -> BufferLength -> IO ()
Encrypt using the ECB mode.
input need to be a multiple of the blocksize
ecbDecryptMutable :: cipher -> PtrDest -> PtrSource -> BufferLength -> IO ()
Decrypt using the ECB mode.
input need to be a multiple of the blocksize
cbcEncryptMutable :: cipher -> PtrIV -> PtrDest -> PtrSource -> BufferLength -> IO ()
encrypt using the CBC mode.
input need to be a multiple of the blocksize
cbcDecryptMutable :: cipher -> PtrIV -> PtrDest -> PtrSource -> BufferLength -> IO ()
decrypt using the CBC mode.
input need to be a multiple of the blocksize
type BufferLength = Word32
