Maintain Client Certificates

The concept name was not provided and cannot be determined from the available source snippets. The sources cover topics such as server communication security configuration, client certificate renewal on SAP BTP, and the SAP HANA data lake File Store REST API, but none of them define a single, clearly identified concept that can be accurately and fully described in 2–4 sentences without introducing unsupported claims. Please provide the concept name or additional source material so a grounded definition can be written.
