Short: md5sum test/build checksums on files Author: simons@peti.GUN.de (Peter Simons) Uploader: Virus Help Team Canada (Charlene) Version: 18-Sep-1993 Type: util/crypt Requires: All Amigas Size: md5sum.lha 31.282 bytes MD5SUM - amiga port by Peter Simons (simons@peti.GUN.de) http://www.cryp.to/#historic-amiga-software Verify this archive with: md5sum -vc md5sum.txt Check the PGP signture with: pgp md5sum.txt What is MD5SUM? =============== MD5SUM is a small utility that allows you to build checksums over text- or binary files, using the "MD5 Message Digest Algorithm". These checksums can be stored in a file and can be validated later, using MD5SUM. For example, the checksums of the MD5SUM sources look like this: 107788ec46ef6ab9dbb190215f5b6f1a source/getopt.c ca1ada43f73cff4466adde1e88a8cf60 source/md5.c 4a6dafa2f6282430e65d4728a1303a53 source/md5sum.c So, what is this useful for? Say, you're releasing a software package including sources to the public and want to make shure, nobody modifies the program (for example: add backdoors) and redistributes the modified version. (Do not laugh, this already happened with BBS packages or common utilities. Once, even a virus was added to a utility!) You could include the digest-file with a checksum of every single file in release archive and everybody could easily check the validity of the files. --------------------------------------------------------------------------- Peter Simons | Usenet: simons@peti.GUN.de | PGP v2.x public key Europaring 20 | CBMNet: simons@peti.adsp.sub.org | available on request 53123 Bonn | Phone: +49 228 746061 | or via GET from almost Germany | CBM: ETG207 | any keyserver.
