- * Generates and validates CSRF tokens.

- * You can generate a CSRF token by using the method {@link generateCsrfToken()}.
- * This method expects a unique token ID as argument. The token ID can later be
- * used to validate a token provided by the user.
- *
- * Token IDs do not necessarily have to be secret, but they should NEVER be
- * created from data provided by the client. A good practice is to hard-code the
- * token IDs for the various CSRF tokens used by your application.
- *
- * You should use the method {@link isCsrfTokenValid()} to check a CSRF token
- * submitted by the client. This method will return true if the CSRF token is
- * valid.
