Simple hash on scratch?
Does anyone know of a simple one-way hash function that can easily be made in scratch?
The number of output bits should be 64, or 16 hexadecimal digits. It needs to exibit the avalanche effect (well, it should to be secure).
I need it for my CM Forum, more specifically, account creation, login/logout, and password protection (mainly this one).
Credit will be given, although I don't know when I can use the hash.

Re: Simple hash on scratch?
Yes, go on vb forums on microsoft.com and look for the triple DES Method.
make it a function in a dll. It is naturally just an reciprocal style encrypt function, but you can turn this into a hash if you use the input as the string and the key.
Hope it works.
