can you encrypt querystring and then decode it?

[andryuha]

Just wondering if there are any ways to encrypt the querystring values and then decode it for request.querystring()?

thanks

Do you have to use QueryStrings... can you post the data instead? (I am assuming the data is coming from a form) Ladyhawk.

yeah, i do have to use QueryString, because a user would click on a generated link (ex. mysite/page.asp?id=5).

So i was wondering if there was a way to encrypt that ?id=5 part of he querysring and then when I retrieve it with request.querystring to decode it to normal.

You could build a function that would do some sort of algorythm on the value of the field, and then pass it, then call a reverse to that function when you want the value back out. But that would have to be done after the Request.querystring. So essentially you would encode it, pass it as a querystring, then take it from the querystring to a local, decode it, and go from there.

I was looking for the same thing and found it on:

uses some kind of encryption to completely disguise the query string.
