Mcrypt is missing


Hello, i have installed opencart on server, and i’m getting error:
Unknown: Function mcrypt_create_iv() is deprecated in /storage/ssd2/731/5456731/public_html/system/library/encryption.php on line 8

In a web i have found information, that it’s necesary to install mcrypt on server to fix this problem.
Is it possible?
