Provides a way to encrypt or hash data (or both) by using the same algorithms and key values that are used for ASP.NET forms authentication and view state.
Assembly: System.Web (in System.Web.dll)
Thetype exposes the following members.
|Decode||Obsolete. Decodes and/or validates data that has been encrypted or provided with a hash-based message authentication code (HMAC).|
|Encode||Obsolete. Encrypts data and/or appends a hash-based message authentication code (HMAC).|
|Protect||Protects the specified data by encrypting or signing it.|
|Unprotect||Unprotects the specified data, which was protected by the Protect method.|
The data to encrypt, hash, decrypt, or validate does not exist
The class provides methods that expose the hashing and encryption logic that ASP.NET provides. For information about which encryption and hashing algorithms ASP.NET uses, and the key values that it uses with them, see machineKey Element (ASP.NET Settings Schema).
The APIs should only be used in an ASP.NET app. Behavior of the MachineKey APIs outside the context of an ASP.NET application is undefined
