Hash String to String/Int

Can someone point me to a good cpan module employing a one way hashing algorithm?

e.g. http://dev.mysql.com/doc/mysql/en/innodb-physical-structure.html maps to 278HGKJZLKLK23 every time.

I need to be able to map a potentially long string (ie a URL) to a shorter string (or integer) so I can effectively index a table.

(i'm not worried about the occasional duplicate, i understand it's not possible to effectively condense every string acturately to a shorter unique string)

Thanks,


Alex
