SECURING
To set up SSL on your server, you need a key ring containing a server certificate from an Internet certificate authority.
You can use a self-signed certificate or one from a third-party certificate authority (CA). A server certificate is a binary file that uniquely identifies the server. The server certificate is stored on the server's hard drive and contains a public key, a name, an expiration date, and a digital signature. The key ring also contains root certificates used by the server to make trust decisions.
Use OpenSSL (available on the Internet) and KYRTool (installed with Domino) to generate a keyring file for Domino servers to use. For instructions, see the article https://support.hcltechsw.com/csm?id=kb_article&sysparm_article=KB0073309 on the HCL Software Support site.
