- 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.
