Subject: [DUG] Hash function for string


I need a function to get a hash value from a string about 100 or so
characters long, ideally giving something only 10-20 characters max - either
a string or number.
 
Any recomendations?
 
Used a simple roll-my own up to now, but it does not work well for more than
about 32 characters - well I think it might possibly give duplicates.
