Security is controlled by digital certificates that act as electronic ID cards. The purpose of a certificate is to assure a program or a user that it is safe to allow the proposed connection and, if encryption is involved, to provide the necessary encryption/decryption keys.
Certificate Management allows you to create such certificates and enable Secure Sockets Layer (SSL) communications between IBM Host On-Demand server and clients.
Use Certificate Management if you need to securely communicate with a host that has a self-signed certificate or a certificate issued by a CA that is not on the trusted list.
The below video demonstrates how to use the Certificate Management Utility to create certificates for GSKIT and JSSE. Users can then use these certificates to make secure connections to host.
