Local certificates
Local certificates are issued for a specific server, or web site. Generally they are very specific, and often for an internal enterprise network. For example a personal web site for John Smith at www.example.com (such as http://www.example.com/home/jsmith) would have its own local certificate.
These can optionally be just the certificate file, or also include a private key file and PEM passphrase for added security.
