I need something similar to md5 that will encode a string such as
"This is a test"
I want to pass the encoded string as a URL parameter, at the landing page I would like to convert it back to a string. I don’t want my site visitors to know what is being passed. Md5 would suit perfectly if there was a way to convert it back to a string. Security for the string is not an issue.
Any help would be appreciated.
