How to use openssl for generating ssl certificates private Oct 18, 2019 How to setup your own CA with OpenSSL · GitHub Each issued certificate must contain a unique serial number assigned by the CA. It must be unique for each certificate given by a given CA. OpenSSL keeps the used serial numbers on a file, by default it has the same name as the CA certificate file with the extension replace by srl. So a file named ca.srl is created: $ cat ca.srl ED4B4A80662B1B4C OpenSSL: Check SSL Certificate Expiration Date and More Info: Run man s_client to see the all available options. As an example, let’s use the openssl to check the SSL certificate expiration date of the https://www.shellhacks.com website: $ echo | openssl s_client -servername www.shellhacks.com -connect www.shellhacks.com:443 2>/dev/null | openssl x509 -noout -dates notBefore=Mar 18 10:55:00 2017 GMT notAfter=Jun 16 10:55:00 2017 GMT

Yes, you can sign you own CSR (Certificate Sign Request) with a given serial number using the OpenSSL "req -x509 -set_serial" command as shown below. Without the "-set_serial" option, the resulting certificate will have random serial number. See the example below:
