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 {@link TPage::getEnableStateValidation() EnableStateValidation} and {@link TPage::getEnableStateEncryption() 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 {@link TApplication::getSecurityManager() SecurityManager}.
