PHP 5.x-8.x polyfill for mcrypt extension.
PHP 5.x-8.x polyfill for mcrypt extension.
With Composer:
composer require phpseclib/mcrypt_compat
mcrypt_compat's ncfb
implementation has some incompatibles with mcrypt's implementation where mcrypt_generic
and mdecrypt_generic
are concerned. The unit tests elaborate.
The mcrypt extension's behavior underwent changes as new versions of PHP were released. By default mcrypt_compat emulates the behavior of PHP 7.1 but if you need to emulate how mcrypt behaved in, say, PHP 5.3.0, you may do so by doing define('PHPSECLIB_MCRYPT_TARGET_VERSION', '5.3.0');
before including vendor/autoload.php (if you're using this with Composer).
