hash package:cryptonite

Hash a strict bytestring into a digest.

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)

Get the block size of a hash algorithm

Get the digest size of a hash algorithm

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.

Initialize a new context for this hash algorithm

Initialize a new context for a specified hash algorithm

Hash the first N bytes of a bytestring, with code path independent from N.

Run the hashPrefix function but takes an explicit hash algorithm parameter

run hashUpdates on one single bytestring and return the updated context.

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

Run the hash function but takes an explicit hash algorithm parameter

Hash a lazy bytestring into a digest.

Get the size of the context used for a hash algorithm

Finalize the context and set the digest raw memory to the right value

Initialize a context pointer to the initial state of a hash algorithm

Update the context with some raw data

Finalize a mutable hash context and compute a digest

Create a new mutable hash context. the algorithm used is automatically determined from the return constraint.

Create a new mutable hash context. The algorithm is explicitely passed as parameter

Reset the mutable context to the initial state of the hash

Update a mutable hash context in place

Create a bcrypt hash for a password with a provided cost value. Typically used to create a hash when a new user account is registered or when a user changes their password. Each increment of the cost approximately doubles the time taken. The 16 bytes of random salt will be generated internally.
