TPageStateFormatter is a utility class to transform the page state into and from a string that can be properly saved in persistent storage.
Depending on the EnableStateValidation and EnableStateEncryption, TPageStateFormatter may do HMAC validation and encryption to prevent the state data from being tampered or viewed. The private keys and hashing/encryption methods are determined by SecurityManager.
