Crypto.Multihash
Description
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
Instances
| Eq a => Eq (MultihashDigest a) Source # | |
| Show (MultihashDigest a) Source # | |
Base usable to encode the digest
class Codable a where Source #
Codable hash algorithms are the algorithms supported for multihashing
Minimal complete definition
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 there are encoding issues or 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. Tha data is 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.
