Alejandro, if you have openssl installed on your computer, you can  
use it to do md4, md5, sha1 and others as shell calls.

Having written a Revolution implementation of the sha1 digest, I  
think it's true to say that if you want to get the digest for whole  
files and stacks, this sort of digest function is likely to be very  
slow in a high-level language like Revolution, so you might be better  
off using the (very fast) openssl tools if you can.
