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.
