  1 review

Jacksum is a free and platform independent software for computing and verifying checksums, CRCs and message digests. Jacksum features both a commandline interface and an open API.

Jacksum supports 58 popular algorithms (Adler32, BSD sum, Bzip2's CRC-32, POSIX cksum, CRC-8, CRC-16, CRC-24, CRC-32 (FCS-32), CRC-64, ELF-32, eMule/eDonkey, FCS-16, GOST R 34.11-94, HAS-160, HAVAL (3/4/5 passes, 128/160/192/224/256 bits), MD2, MD4, MD5, MPEG-2's CRC-32, RIPEMD-128, RIPEMD-160, RIPEMD-256, RIPEMD-320, SHA-0, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, Tiger-128, Tiger-160, Tiger, Tiger2, Tiger Tree Hash, Tiger2 Tree Hash, Unix System V sum, sum8, sum16, sum24, sum32, Whirlpool-0, Whirlpool-1, Whirlpool and xor8).

Some of the additional features include:

- Fully customizable output
- Customized CRC algorithms and support for combination of multiple algorithms
- By default, output is 100% compatible with Unix-standard tools such
as sum, cksum, md5sum and sha1sum
- Supports verification of both the content and timestamp of files
- Large file aware
- Recursive file processing

Very powerful and useful. It is possible to run somewhat complex scripts to compare whole folder structures of files. Supports almost every hash function. Feels like I've been using it for almost twenty years now.
