Types
Represent a context for a given hash algorithm.
Represent a digest for a given hash algorithm.
Functions
digestFromByteString :: (HashAlgorithm a, ByteArrayAccess ba) => ba -> Maybe (Digest a) Source #
Try to transform a bytearray into a Digest of specific algorithm.
If the digest is not the right size for the algorithm specified, then Nothing is returned.
hash methods parametrized by algorithm
hashInitWith :: HashAlgorithm alg => alg -> Context alg Source #
Initialize a new context for a specified hash algorithm
hashWith :: (ByteArrayAccess ba, HashAlgorithm alg) => alg -> ba -> Digest alg Source #
Run the hash function but takes an explicit hash algorithm parameter
hash methods
hashInit :: HashAlgorithm a => Context a Source #
Initialize a new context for this hash algorithm
hashUpdates :: (HashAlgorithm a, ByteArrayAccess ba) => Context a -> [ba] -> Context a Source #
Update the context with a list of strict bytestring, and return a new context with the updates.
hashUpdate :: (ByteArrayAccess ba, HashAlgorithm a) => Context a -> ba -> Context a Source #
run hashUpdates on one single bytestring and return the updated context.
hashFinalize :: HashAlgorithm a => Context a -> Digest a Source #
Finalize a context and return a digest.
hashBlockSize :: HashAlgorithm a => a -> Int Source #
Get the block size of a hash algorithm
hashDigestSize :: HashAlgorithm a => a -> Int Source #
Get the digest size of a hash algorithm
hash :: (ByteArrayAccess ba, HashAlgorithm a) => ba -> Digest a Source #
Hash a strict bytestring into a digest.
hashlazy :: HashAlgorithm a => ByteString -> Digest a Source #
Hash a lazy bytestring into a digest.
