About creating certificates for Splunk
There are multiple ways you can create signed certificates, depending upon your organizations policies, your platform, and the tools that you are using. If you have already generated these certificates and key, or if you are experienced in generating certificates, you can skip this task and go directly to the configuration topic "Secure Splunk Web with your own certificate" in this manual.
Since self-signed certificates are signed by your organization, they are not contained in browser certificate stores. As a result, web browsers consider self-signed certificates "untrusted". This produces a warning page to users and may even prevent access for the user.
