The Machine Key feature can be managed to specify hashing and encryption settings for application services such as view state, Forms authentication, membership and roles, and anonymous identification. The following validation methods are available ... The .NET 4.x root web.config machineKey validation must be HMACSHA256 (HMACSHA384/512 are also accepted as stronger).
