        MD5SUM - amiga port by Peter Simons <simons at peti.GUN.de>


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.
