You could encode the querystring when writing it into HTML as a
link and then decode it when you receive the page using a reverse
algorithm. For example, write the link as page.a4d?
kdfh=89df798sdf79s8f and then use MD5 to decode the value and
variable name. That way, both the query string variable name and
value are both hidden, and can't be easily decrypted.
Would you mind sharing a little more info on this technique?
Certainly not enough to compromise your system, but could you say
how you are encoding/decoding to MD5 and how you are making the
encoded values web safe.
You can't decode MD5. It's a one-way hash. I would still like to know
_why_ you want to encrypt the link, that will help me suggest a
solution.
