Hi Folks ! I want to create 5 certificates from a single self-signed CA. I 've been able to create 3 certificates as of now. However, only the first certificate of mine is working with the root certificate, the other 2 are not working. The later 2 certificates are created from the same CA.crt and CA.key as were used to create the first certificate.
The differences that lie with all the 3 certificates are as below: 1. Common Name 2. Subject and DNS name in the SubjectAltName 3. Serial Number of the certificates. (with number 2 and 3 choosen for the later created 2 certificates) Frankly. I do not how to create multiple certifiacates from a single self-signed CA. Please some one guide me in this. Also, my CA.crt and CA.key have already been flashed to the device, so I do not have any option of re-creating the CA.crt and CA.key. I saw some where on a post that separate CA.keys need to be developed as well for creating multiple certificates. Is this true? If Yes, do I need to create the new CA.key for every new certificate to be certified by this single CA, keepig in consideration that CA.crt and 1 CA.key have already been flashed to the device? Please some help and elaborate me on this. Thanks and regards, Rajat
