Recursive Hasher

RHash is a console utility for computing and verifying hash sums of
files. It supports CRC32, MD4, MD5, SHA1, Tiger, DC++ TTH, BitTorrent
BTIH, AICH, EDonkey 2000 hash, GOST R 34.11-94, RIPEMD-160, HAS-160,
Whirlpool, Snefru-128 and Snefru-256 algorithms. Hash sums are used to
ensure and verify integrity of large volumes of data for a long-term
storing or transferring.

Features:

* Calculation of magnet links and EDonkey 2000 links.
* Updating of existing hash files (adding sums of files missing
  in the hash file).
* Output in a predefined (SFV, BSD-like) or user defined format.
* Ability to process directories recursively.
