PHP's alternative to mcrypt_get_iv_size()

anjanesh

Fatal error: Uncaught Error: Call to undefined function mcrypt_get_iv_size()
I think newer versions of PHP (since 7.2 ?) have mcrypt_get_iv_size removed.
Google's AI says this :

sudo apt-get install php-mcrypt
sudo phpenmod mcrypt
sudo service apache2 restart # or php-fpm restart if using Nginx

What are the alternatives ?

anjanesh perhaps you could use openssl_cipher_iv_length in your code instead of the deprecated mcrypt_get_iv_size function.

If that doesn't meet your needs then you can instead build your own PHP stack with whatever features you need and use that to serve your application.

What about composer require phpseclib/mcrypt_compat ?

sean

anjanesh if your project uses composer then yes, you can try that.
