Multihash library built on top of haskell cryptonite
crypto package
Multihash is a protocol for encoding the hash algorithm and digest length
at the start of the digest, see the official
multihash poroposal github repo.
The library re-exports the needed types and typclasses from Algorithms
namely HashAlgorithm
, SHA1
, SHA256
, SHA512
, SHA3_512
, SHA3_384
,
SHA3_256
, SHA3_224
, Blake2b_512
, Blake2s_256
.
For additional informations refer to the README.md or the gihub repository.

Multihash Types
data MultihashDigest a Source #
Multihash Digest container
Eq a => Eq (MultihashDigest a) Source # | |
Show (MultihashDigest a) Source # | |
Base
usable to encode the digest
Multihash helpers
encode :: (HashAlgorithm a, Codable a, Show a) => Base -> MultihashDigest a -> Either String String Source #
Safe encoder for MultihashDigest
.
encode' :: (HashAlgorithm a, Codable a, Show a) => Base -> MultihashDigest a -> String Source #
Encoder for MultihashDigest
.
Throws an error if the MultihashDigest
length field does not match the Digest
length.
multihash :: (HashAlgorithm a, Codable a, ByteArrayAccess bs) => a -> bs -> MultihashDigest a Source #
Helper to multihash a ByteArrayAccess
(e.g. a ByteString
) using a supported hash algorithm.
multihashlazy :: (HashAlgorithm a, Codable a) => a -> ByteString -> MultihashDigest a Source #
Helper to multihash a lazy ByteString
using a supported hash algorithm.
checkMultihash :: ByteArrayAccess bs => ByteString -> bs -> Either String Bool Source #
Check the correctness of an encoded MultihashDigest
against the data it
is supposed to have hashed, passed as a ByteArrayAccess
(e.g. a BinaryString
).
Re-exported types
class HashAlgorithm a #
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.
