	Can I assume that the field contains just numbers?
If that is the case, how about running the number through
BASE() and change it from base 10 to say base 36 and then
back again at the other side?

	If you have alphanumeric data, I wrote a base64/mime
encryption subroutine in filePro. Throw me a bone and I'll
share it with you.
