RHash Program RHash (Recursive Hasher) is a console utility for computing and verifying hash sums of files. It supports CRC32, MD4, MD5, SHA1, SHA256, SHA512, Tiger, DC++ TTH, BitTorrent BTIH, ED2K, AICH, GOST R 34.11-94, RIPEMD-160, HAS-160, EDON-R 256/512, Whirlpool and Snefru-128/256 algorithms. Hash sums are used to ensure and verify integrity of large volumes of data for a long-term storing or transferring. Features: Can calculate Magnet links. Output in a predefined (SFV, BSD-like) or user defined format. Ability to process directories recursively. Updating of existing hash files (adding sums of files missing in the hash file). Calculates several hash sums in one pass. Portability: the program works the same under Linux, *BSD, or Windows. RHash is written in pure C, small in size and is distributed under Open Source License. Download RHash.
