The Secure Sockets Layer (SSL) protocol uses certificates on the client and server to store encryption keys. The server provides its SSL certificate when a connection is made so that the client can verify the server identity. The server can also request a certificate from the client to provide mutual authentication of both sides of the connection.
Certificates are stored in a centralized store according to the IP address and port number of the connection. The special IP address 0.0.0.0 matches any IP address for the local machine. Note that the certificate store does not distinguish URLs based on the path. Services with the same IP address and port combination must share certificates even if the path in the URL for the services is different.
