UCMDB Cert is due to expire

We can manage two different certificates on UCMDB, the self-signed certificate and the Certification Authority certificate(CAC). The self-signed is one certificate we can generate by our own means, without contacting any CA. For the CA signed certificates they ask for a CSR, which means Certificate Signing Request, this is .csr file that contains the information that will be on the certificate, it is kind of a template so the CA can have the information of your company and start filling the certificate. You can see more information here: https://www.sslshopper.com/what-is-a-csr-certificate-signing-request.html.
I have found this free CSR generator: https://www.ssltrust.com.au/ssl-tools/generate-csr. Once you fill the required information and click “Generate CSR” it will display two things:
• The CSR code: You just need to copy that text into notepad and save it as .csr file. This is what you need to send to the CA.
• Private key: You do not need to share this with any other person. You just copy the code for te private key into notepad and save it.
