PHP 7 Compatibility

Hi, we are testing our sites for PHP 7 compatibility. The Cloudflare plugin yields these errors:

FILE: /wp-content/plugins/cloudflare/vendor/cloudflare/cloudflare-plugin-backend/src/SecurityUtil.php
——————————————————————————————————————————————————
FOUND 2 ERRORS AFFECTING 1 LINE
——————————————————————————————————————————————————
16 | ERROR | Extension ‘mcrypt’ is deprecated since PHP 7.1 and removed since PHP 7.2; Use openssl (preferred) or pecl/mcrypt once available instead
16 | ERROR | Function mcrypt_create_iv() is deprecated since PHP 7.1 and removed since PHP 7.2; Use random_bytes() or OpenSSL instead

Can you help address them?
