hashing tool supporting several hashes and recursivity

 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.
 .
 Hashrat also supports directory recursion, hashing entire devices,
 generating a hash for an entire directory, operations in remote machines
 and several other features. It has a 'CGI' mode that can be used as a
 web-page to lookup hashes.
 .
 This tool is useful in forensics investigations and network security.
