How to encrypt and decrypt data in MVC?

Answer 1

You don't need to encrypt data from the controller to the view since the view rendering happens in the same computer that the controller is operating.

If you want to encrypt the page that is sent to the user you should use a ssl connection

Here you have an example that encrypts only the "id", this is done for security so that data is not looking for "id".

In this case you have to encrypt and decrypt the property:
