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.

Best,

Mark

What are the advantages of MD4 over Rev's built-in MD5?


MD4 is used by the rsync utility for "synchronizing files and directories
from one location to another while minimizing data transfer"

For some time, i have been interested in adding this kind of
functionality to stacks used in this platform.

Thanks a lot for your interest!
