- * Check whether a user-provided string is equal to a fixed-length secret string
- * without revealing bytes of the secret string through timing differences.
- *
- * The usual way to compare strings (PHP's === operator or the underlying memcmp()
- * function in C) is to compare corresponding bytes and stop at the first difference,
- * which would take longer for a partial match than for a complete mismatch. This
- * is not secure when one of the strings (e.g. an HMAC or token) must remain secret
- * and the other may come from an attacker. Statistical analysis of timing measurements
- * over many requests may allow the attacker to guess the string's bytes one at a time
- * (and check his guesses) even if the timing differences are extremely small.
- *
- * When making such a security-sensitive comparison, it is essential that the sequence
- * in which instructions are executed and memory locations are accessed not depend on
- * the secret string's value. HOWEVER, for simplicity, we do not attempt to minimize
- * the inevitable leakage of the string's length. That is generally known anyway as
- * a chararacteristic of the hash function used to compute the secret value.
- *
- * Longer explanation: http://www.emerose.com/timing-attacks-explained

- * @param string $known_string Fixed-length secret string to compare against
- * @param string $user_string User-provided string
