Description

Generalized cryptographic hash interface, that you can use with cryptographic hash algorithm that belong to the HashAlgorithm type class.

import Crypto.Hash

sha1 :: ByteString -> Digest SHA1
sha1 = hash

hexSha3_512 :: ByteString -> String
hexSha3_512 bs = show (hash bs :: Digest SHA3_512)

Synopsis

Types

class HashAlgorithm a where #

Class representing hashing algorithms.

The hash algorithm is built over 3 primitives:

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

Minimal complete definition

hashBlockSize, hashInit, hashUpdates, hashFinalize, digestFromByteString

Methods

hashBlockSize :: Context a -> Int #

Block size in bytes the hash algorithm operates on

hashInit :: Context a #

Initialize a new context for this hash algorithm

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

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

hashFinalize :: Context a -> Digest a #

Finalize a context and return a digest.

digestFromByteString :: ByteString -> Maybe (Digest a) #

Try to convert a binary digest bytestring to a digest.
