Hashrat 1.25 (The man file)

Hashrat is a hash-generation utility that supports the
md5, sha1, sha256, sha512, whirlpool, jh-244, jh256, jh-384 and jh-512
hash functions, and also the HMAC versions of those functions.

It can output in 'traditional' format (same as md5sum and shasum and the like),
or it's own format. Hashes can be output in octal, decimal, hexadecimal,
uppercase hexadecimal or base64. It supports directory recursion, hashing
entire devices, and generating a hash for an entire directory. It has
a 'CGI' mode that can be used as a web-page to lookup hashes.
