need encryption algorithm

[Hugh]

Hi all,
  I need a simple encryption algorithm that will not give me
characters that I can't store in my oracle table. At the moment I'm
using the rotor encryption module because I like it's simple interface
but It's generating characters that oracle can't store which is a damn
pain. What other modules are available that are easy to use and will
do what I wan't. Remember that security is not paramount here, I'm
only including it for functionality.

Thanks,
