#### [OpenSSL changes in PHP 5.6.x](http://php.net/manual/en/migration56.openssl.php) ###### Stream wrappers now verify peer certificates and host names by default when using SSL/TLS - Add openssl config in php.ini ```bash [openssl] openssl.cafile = "/path/to/server.pem" openssl.capath = "/path/to/" ``` - When you generate a server.pem, the CA's common name (CN) should be same as your server's domain name or IP.
