[BNM] MD5 quicky

[Richard Maynard - Wessex Networks]

I think you are perhaps overcomplicating things.

When MD5 is usually used -  you'd start with a password - run it through the
MD5 algorithm to give you your hash - and then store it.  When you then want
to validate a password, you'd take the password received, MD5 it like you
did before and then compare the 2 hashes.  If the hashes match then the
password is correct.

You can't "validate" in the sense you are thinking an MD5 hash, only compare
it to another hash.

Regards,

Richard.

Hey

Does anyone here have an understanding of MD5 who can spare a minute or two
to explain to me what it's all about.

I have a security token I need to validate and its comming over as an MD5
hash. I can see how to [they] create the hash, I just don't see what I'm
meant to do to validate it. I'm using .NET but don't think that should
matter as it's only the understanding of MD5 bit that's buggered me.

Cheers
