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

hexSha3_512 bs = show (hash bs :: Digest SHA3_512)Represent a context for a given hash algorithm.
This type is an instance of ByteArrayAccess for debugging purpose. Internal layout is architecture dependent, may contain uninitialized data fragments, and change in future versions. The bytearray should not be used as input to cryptographic algorithms.
NFData (Context a)Defined in cryptonite-0.30 · Crypto.Hash.TypesByteArrayAccess (Context a)Defined in cryptonite-0.30 · Crypto.Hash.TypesRepresent a digest for a given hash algorithm.
This type is an instance of ByteArrayAccess from package memory. Module Data.ByteArray provides many primitives to work with those values including conversion to other types.
Creating a digest from a bytearray is also possible with function
digestFromByteString.

If the digest is not the right size for the algorithm specified, then Nothing is returned.
Initialize a new context for a specified hash algorithm
Run the hash function but takes an explicit hash algorithm parameter
Run the hashPrefix function but takes an explicit hash algorithm parameter
Initialize a new context for this hash algorithm
Update the context with a list of strict bytestring, and return a new context with the updates.
run hashUpdates on one single bytestring and return the updated context.
Finalize a context and return a digest.
Update the context with the first N bytes of a bytestring and return the digest. The code path is independent from N but much slower than a normal hashUpdate. The function can be called for the last bytes of a message, in order to exclude a variable padding, without leaking the padding length. The begining of the message, never impacted by the padding, should preferably go through hashUpdate for better performance.
Get the block size of a hash algorithm
Get the digest size of a hash algorithm
Hash a strict bytestring into a digest.
Hash the first N bytes of a bytestring, with code path independent from N.
Hash a lazy bytestring into a digest.
