If it helps any, there is a collection of encryption routines in .dll format on sable.ox.ac.uk - they're in a file called wincrdll.zip. The zip file includes the .dlls, source code, and brief explanatory text. The routines are DES, IDEA, MD5, and an MD5 variant the author is calling MDC (?).

I got the name MDC from the original posting of the method by Phil Karn to sci.crypt a number of years ago and it seemed sensible to retain it. Just a small point. Regard, - Andy
