Description

Crypto hash main module

Synopsis

Types

class HashAlgorithm a whereSource

Class representing hashing algorithms.

The hash algorithm is built over 3 primitives:

init : create a new context updates : update the context with some strict bytestrings finalize : finalize the context into a digest

Methods

hashInit :: Context aSource

Initialize a new context for this hash algorithm

hashUpdates :: Context a -> [ByteString] -> Context aSource

Update the context with a list of strict bytestring, and return a new context with the updates.

hashFinalize :: Context a -> Digest aSource

Finalize a context and return a digest.

data Context a Source

Represent a context for a given hash algorithm.

data Digest a Source

Represent a digest for a given hash algorithm.

Instances

Eq (Digest a)
Eq (Digest a) => Ord (Digest a)
Show (Digest a)

Functions

digestToByteString :: Digest a -> ByteString Source

Return the binary digest

digestToHexByteString :: Digest a -> ByteString Source

Return the hexadecimal (base16) bytestring of the digest

hash :: HashAlgorithm a => ByteString -> Digest aSource

Hash a strict bytestring into a digest.

hashlazy :: HashAlgorithm a => ByteString -> Digest aSource

Hash a lazy bytestring into a digest.

hashUpdate :: HashAlgorithm a => Context a -> ByteString -> Context aSource

run hashUpdates on one single bytestring and return the updated context.
