I have a CGI form validator which pretty much just makes a random image with numbers and letters that you must time in.

Uptil now I passed the value of the characters in the form HIDDEN tag, which of course isn't secure. What other options do I have?

I was looking at CGI::Session, but is creating session variables really an efficient way to do this when every time they hit the screen the values will change? I'd think cookies would cause the same problem of inefficiencies.

Then there is encryption..I would need something that comes with Perl (or easy to install on my webhost) that not only encrypts a string but can also decrypt it back into the original information so I can check it. This to me sounds like the best method. Anyone know of a nice module for this?

What are your thoughts and ideas?
