ParagonIE_Sodium_Compat::runtime_speed_test() public WP 1.0

Runtime testing method for 32-bit platforms.

Usage: If runtime_speed_test() returns FALSE, then our 32-bit implementation is to slow to use safely without risking timeouts. If this happens, install sodium from PECL to get acceptable performance.

true|false. TRUE if we're fast enough, FALSE is not

Использование

$result = ParagonIE_Sodium_Compat::runtime_speed_test( $iterations, $maxTimeout );
