How do I create a self-signed SSL Certificate for testing purposes?
Make sure OpenSSL is installed and in your PATH.
Run the following command, to create server.key and server.crt files:
# openssl req -new -x509 -nodes -out server.crt -keyout server.key
 These can be used as follows in your httpd.conf file: 
             SSLCertificateFile    /path/to/this/server.crt
             SSLCertificateKeyFile /path/to/this/server.key

It is important that you are aware that this server.key does not have any passphrase. 
To add a passphrase to the key, you should run the following command, 
and enter & verify the passphrase as requested.
# openssl rsa -des3 -in server.key -out server.key.new
# mv server.key.new server.key
 Please backup the server.key file, and the passphrase you entered, in a secure location.

-Aggiungere in httpd.conf al fondo:
