软件包：jacksum（1.7.0-4.1）
computes checksums, CRCs and message digests
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
