Description

Generalized impure cryptographic hash interface

Synopsis

- class HashAlgorithm a where
- data MutableContext a
- hashMutableInit :: HashAlgorithm alg => IO (MutableContext alg)
- hashMutableInitWith :: HashAlgorithm alg => alg -> IO (MutableContext alg)
- hashMutableUpdate :: (ByteArrayAccess ba, HashAlgorithm a) => MutableContext a -> ba -> IO ()

- hashMutableReset :: HashAlgorithm a => MutableContext a -> IO ()

# Documentation

class HashAlgorithm a where #

Class representing hashing algorithms.

The interface presented here is update in place and lowlevel. the Hash module takes care of hidding the mutable interface properly.

Minimal complete definition

hashBlockSize, hashDigestSize, hashInternalContextSize, hashInternalInit, hashInternalUpdate, hashInternalFinalize

Methods

hashBlockSize :: a -> Int #

Get the block size of a hash algorithm

hashDigestSize :: a -> Int #

Get the digest size of a hash algorithm

hashInternalContextSize :: a -> Int #

Get the size of the context used for a hash algorithm

hashInternalInit :: Ptr (Context a) -> IO () #

Initialize a context pointer to the initial state of a hash algorithm

hashInternalUpdate :: Ptr (Context a) -> Ptr Word8 -> Word32 -> IO () #

Update the context with some raw data

hashInternalFinalize :: Ptr (Context a) -> Ptr (Digest a) -> IO () #

Finalize the context and set the digest raw memory to the right value
