Encrypt/Decrypt script.

This is my first time posting to the ASP section here at PSC. I just wrote this for a requirement on one of my projects and thought I would share. I did look and see there are already other Encryption posts, but hey, thought one more would be ok. Very simple and short code to encrypt/decrypt a string. Main requirement for this was we just wanted it so a person would not see a records SSN value in the URL. It is a closed Intranet site but we just wanted to be kind and not just have SSN numbers up on screens and printed pages. Hope it helps somebody. This is actually just some VB code I had from long long ago and just ported over to ASP for the first time. Was happy to see it worked.
