module CryptoHash

@INTERNAL: Please use ObjectHash.hash() instead. Contains functions which cryptographically hash an input string, using a given algorithm. Several common algorithms are implemented, or you can provide your own Digest object.

Constants

ALGORITHMS: Algorithms which can cryptographically hash an input.

@INTERNAL: Please use ObjectHash.hash() instead. Call the appropriate algorithm on the input. @param input A string to hash. @param algorithm Either a string for an algorithm to use, or a Digest to perform the hash.
