We have done different things to make CF encryption give us safe characters.
First, when we started looking at url variable encryption, we used
URLencodedFormat() on the encrypted value so that netscape wouldn't freak
out. Then someone on the list mentioned the undocumented functions
cfusion_encrypt and decrypt. These only use "safe" alphanumeric characters.
These have been working out for us just fine, and we are even using it to
write to the DB.

Hello
>> safe characters...
I sometimes have problems with the encrypt functions. Can someone point me
"where can I learn the safe characters"?
thanks,
Mahmut
