Hi

Forgive me for posting with Outlook Express, but my work obligates me to use
these foul tools occasionally. Also, it only makes me appreciate gnus that
much more.

Secure Hashing Algorithm 1
This is the revision of SHA [also called SHA0] which is an alogrithm to
produce a message hash [or digest] of a given file. Hashes are used to
ensure that a file is not tampered with since changing even one charachter
of a file will produce a different hash. Hashes are smaller than the
message, so they provide a means to check that a file was not changed.
