... Consider MD2, MD4, and MD5 for starters. Implementation descriptions
as well as nicely commented C code is available for all of these in either
RFCs or RFCs-to-be...
[choice] The security working group has already
undertaken this task, and as far as I know has resolved that MD5 is the
algorithm of choice...
A specific pointer to an MD5 description and/or code sample would be useful
to those of us who have an immediate interest in experimenting with this
but haven't been following the security doings.
