Enableviewstatemac Attribute In Asp.Net

In this article, we will discuss the EnableViewStateMac attribute in asp.net.

How Enableviewstatemac Ensure Viewstate Integrity?

ViewState is stored on the client side, typically as a hidden field on the page, and is posted back to the server on each postback. Since this data resides on the client, it is vulnerable to tampering. EnableViewStateMac adds a hash (MAC) to the ViewState to verify that the data sent back to the server has not been modified by the client.

Protection Against Attacks

EnableViewStateMac when enabled, it prevents malicious users from manipulating ViewState data (e.g., by injecting or modifying values) that could potentially compromise the application.

Default Setting

In modern ASP.NET applications, EnableViewStateMac is enabled by default for security reasons. It is considered a best practice to keep this enabled unless there is a specific reason not to.
