Does anyone know the command to determine if OpenSSL and mod_ssl are installed on Apache2?

The Apache HTTP Server module mod_ssl provides an interface to the OpenSSL library, which provides Strong Encryption using the Secure Sockets Layer and Transport Layer Security protocols.
mod_ssl is an optional module for the Apache HTTP Server. It provides strong cryptography for the Apache v1. 3 and v2 webserver via the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) cryptographic protocols by the help of the Open Source SSL/TLS toolkit OpenSSL.

If you have PHP installed on your server, you can create a php file, let's called it phpinfo.php and add this <?php echo phpinfo();?>, and open the file in your browser, this shows information about your system environment, to quickly find info about your Apache loaded modules, locate 'Loaded Modules' on the resulting page.

If you have PHP installed on your server, you can chek it in runtime using "extension_loaded" funciontion. Just like this:
<?php if (!extension_loaded('openssl')) { // no openssl extension loaded. } ?> If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
