Mcrypt PHP extension required.

I tried to locate mcrypt.so and change the path in mycrpt.ini but i still get the same error i only get this error i Laravel projects

Solution 1

Had the same issue - PHP7 missing mcrypt.

This worked for me in Ubuntu Please try below commands.

sudo apt-get update
sudo apt-get install mcrypt php7.0-mcrypt
sudo apt-get upgrade

Then restarts apache

sudo service apache2 restart

Hope this commands helps!

Solution 2

First Check whether the mcrypt PHP module is present:

$ php -m | grep mcrypt

To install the mcrypt PHP module we first need to satisfy the following prerequisites:

sudo apt install php-dev libmcrypt-dev php-pear

Now we are ready to install mcrypt PHP module on our Ubuntu 18.04 system:

$ sudo pecl channel-update pecl.php.net
$ sudo pecl install mcrypt-1.0.1

Open the /etc/php/7.2/cli/php.ini file and insert:

extension=mcrypt.so

All done. When successful, checking for the presence of the mcrypt PHP module should produce the following output:

$ php -m | grep mcrypt
mcrypt

Then restarts apache

sudo service apache2 restart

It is best not to use mcrypt, it is abandonware, has not been updated in years and does not support standard PKCS#7 padding, only non-standard null padding that can't even be used with binary data. Instead consider using defuse, it is being maintained and is correct.

I'd recommend doing composer require phpseclib/mcrypt_compat. That'll install a pure-PHP mcrypt shim that'll eliminate the need for the mcrypt extension.

For anyone reading my comment, don't forget to restart apache

Could your maybe add in the answer that it is deprecated in 7.1.x and will be removed in 7.2.x? Source: php.net/manual/de/migration71.deprecated.php

@Ankit Sompura please tell the solution for windows

To update - some docs say that php mcrypt is no longer supported in around PHP7.2. On a debian server I had to specifty to Install php7.2-dev instead of php-dev (because if you install php-dev, it installs the latest php7.4-dev). Note to not install any other version of the php extensions other than 7.2 (prefixing everything with php7.2-). You can check what version your php-cli is using by typing php -v
