$disableFallbackForUnitTestsboolpublic static

This parameter prevents the use of the PECL extension.

$fastMultboolpublic static

Use fast multiplication rather than our constant-time multiplication implementation. Can be enabled at runtime. Only enable this if you are absolutely certain that there is no timing leak on your platform.
