Certificate authority

A third-party that issues a digital certificate to verify the ownership of a public key by the named subject of the certificate. This ensures the reliability of the private key that corresponds to the certified public key. A common use for certificate authorities is to sign certificates used in HTTPS, the secure browsing protocol.

The differences between CA signed and self-signed certificates are in the level of security that the certificate ensures. A trusted certificate protects against malicious attacks that can happen when data is en route over the internet from one system to another.

Scuba comes with a self-signed certificate that is sufficient for getting a system up and running, or for operating in test environments, but is not recommended for production environments.
