Jens Axel Søgaard has an MD5 implementation:

   http://www.scheme.dk/md5/

I used this just recently and have a PLT module version at hand:

   http://www.cs.uvm.edu/~dvanhorn/scheme/md5.ss (or .plt)

Also there is Patrick Ekman's bindings for the mhash library for crytographic
hashes (http://mhash.sourceforge.net/):
