Description

Generalized impure cryptographic hash interface

Synopsis

Documentation

class HashAlgorithm a where Source #

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.

Methods

hashBlockSize :: a -> Int Source #

Get the block size of a hash algorithm

hashDigestSize :: a -> Int Source #

Get the digest size of a hash algorithm

hashInternalContextSize :: a -> Int Source #

Get the size of the context used for a hash algorithm

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

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

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

Update the context with some raw data

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

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

data MutableContext a Source #

A Mutable hash context

Instances

hashMutableInit :: HashAlgorithm alg => IO (MutableContext alg) Source #

Create a new mutable hash context.

the algorithm used is automatically determined from the return constraint.

hashMutableInitWith :: HashAlgorithm alg => alg -> IO (MutableContext alg) Source #

Create a new mutable hash context.

The algorithm is explicitely passed as parameter

hashMutableUpdate :: (ByteArrayAccess ba, HashAlgorithm a) => MutableContext a -> ba -> IO () Source #

Update a mutable hash context in place

hashMutableFinalize :: HashAlgorithm a => MutableContext a -> IO (Digest a) Source #

Finalize a mutable hash context and compute a digest

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

Reset the mutable context to the initial state of the hash
