The Encrypt library requires the Mcrypt extension error

Question

I am getting this error message in CI and I am using XAMPP:

An Error Was Encountered

The Encrypt library requires the Mcrypt extension.

I already look for other similar post but still have not found the right answer.

I try this adding this script in my php.ini XAMPP:

extension=php_mcrypt.dll

line 887.

and restart my xampp. but the same error still appears.

Thanks.

So most likely the extension is NOT loaded, right? Have you checked if it IS loaded? How? What do your http servers log files say? What does a ``phpinfo()`` say about the extension? Have you installed the extension at all? — arkascha, Aug 13 '18 at 05:47

I was getting this error because i had switched from XAMPP(php5) to XAMPP(php7), for this I replaced my old CI->system->libraries->encrypt.php with new file here:encrypt.php, and it worked.

In this new file we check if mcrypt_encrypt is supported or not in __construct function with code below

   $this->_mcrypt_exists = ( ! function_exists('mcrypt_encrypt')) ? FALSE : TRUE;

and based on that we use different function between mcrypt_encode and _xor_encode like that.

Just to know, if you see this old file in __construct function you will see actual error checking

    if (($this->_mcrypt_exists = function_exists('mcrypt_encrypt')) === FALSE)
    {
        show_error('The Encrypt library requires the Mcrypt extension.');
    }

It worked for me.

It finally works after I move the server from PHP 7 to PHP 5 xampp server.
