RapidCRC is an open source CRC/MD5/SHA hashing program.

This is a mod of the original RapidCRC .

The current unicode support was extended to allow writing of unicode .sfv/.md5/.sha1/.sha256/.sha512 files, which can be turned on/off through the settings page. Unicode sfv files are written as UTF-16LE with BOM or UTF-8 (with or without BOM), and RCRC performs a codepage detection.

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.
