I would like to begin by saying that I have no experience with VB.NET. I have a vendor that wants to show my website through an iframe and is sending a query string to validate the user with the url parameter of the iframe tag. He would like to encrypt the variables within the query string. I have demonstrated the encryption with ColdFusion utilitizing the encrypt tag and the attributes of a given passkey (ex. TestPass), the AES algorithm and Hex encoding. The line would look like the below.
My question is... how do I encrypt the same string with VB.NET?
