There are generally two options for obtaining a digital certificate (and a private key).
- You can generate your own certificate using the Cerberus Create Self-Signed Cert button.
- You can obtain a certificate from a recognized Certificate Authority. Cerberus can help you create the Certificate Signing Request. See Creating a Certificate Signing Request for more information.
Which is more appropriate really depends upon your goals. If you just want to make sure that client and server connections are securely encrypted then a self-signed certificate is all you need. It has the benefit of being easily created through Cerberus and completely free.
