Creating a selfsigned SSL Certificate

openssl genrsa 2048 > my.key
openssl req -new -x509 -nodes -sha1 -days 3650 -key my.key > my.cert
openssl x509 -noout -fingerprint -text < my.cert > my.ca

This creates:

my.key - The key file
my.cert - The Certificate file
my.ca - The CACert file

Note: Change -days to any number of days for expire (Then you have to generate a new one).

Those three files can be imported fine in HyperVM/Kloxo.
