  Tutorial: ASP Security Encrypting Query String Values Tutorial

This tutorial along with a piece of code will show you how to encrypt your query string values.

Tutorial Details:

Security issues using a query string

Problem with Query String Method

Often time we use query string collection to retrieve an unique record from a table. Notice the following piece of code -
Detail.asp?RecordID=200

Here we are passing a query string value called " RecordID " using the url. We then use the Query String collection " RecordID " to get the actual number -
<%
Dim RecordID
RecordID = Request.QueryString("RecordID")
%>

The problem with the above method is that we are exposing " RecordID " to the public. Hence making easy to hackers to just change the RecordID Query string to retrieve other values of the table.
