They can be combined with a secret key to produce a message authentication code. They also serve as a cryptographic primitive used in digital signature schemes.

NIST also provide a number of test vectors to verify correctness of implementation.

In this JavaScript implementation , I have tried to make the script as clear and concise as possible, and equally as close as possible to the NIST specification, to make the operation of the script readily understandable. This script is oriented toward hashing text messages rather than binary data. The standard considers hashing byte-stream or bit-stream messages only. Text which contains multi-byte characters outside ISO i. Note that what is returned is the textual hexadecimal representation of the binary hash.

This can be useful for instance for storing hashed passwords, but if you want to use the hash as a key to an encryption routine, for example, you will want to use the binary value not this textual representation.
