Fatal error: Call to undefined function openssl_random_pseudo_bytes()

Solution 1:

I had the same issue. I solved it by editing my php.ini file - changing ;extension=php_openssl.dll to extension=php_openssl.dll .

(For my installation, my php.ini file was located in my P:\Program Files\EasyPHP-12.1\conf_files\ directory.)

Solution 2:

Your version of PHP wasn't compiled with the openssl module. If you are building from source, add the module like so:

cd /path/to/php-5.4/
./configure --with-openssl

Solution 3:

It means you do not have the openssl extension enabled in your PHP install. It needs to be enabled for you to use openssl_* functions.

Solution 4:

It means you possibly don't have openssl enabled.

If you are on windows its even easier to load it. Enable it from wamp icon on system tray.

Solution 5:

Your php installation either does not have openssl enabled, or you could be running a version of php < 5.3.

To enable openssl, you must re-compile and install php with the "–with-openssl" flag. See php installation documentation
