If you have designed a Web platform that uses client-side SSL authentication you probably need to create a client SSL certificate to share with your clients. I added steps of creating a new Client certificate with OpenSSL commands.
At the start of operation we assume that you have these files;
- Server SSL Root CA (CasesupRootCA.crt)
- Server SSL Root Pem (CasesupRootCA.pem)
Step 1: Create Certificate Request File
#openssl req -out CasesupClient.csr -new -newkey rsa:2048 -nodes -keyout CasesupClient.key
Step 2:Sign this request with ROOT CA
#openssl x509 -req -days 765 -in CasesupClient.csr -CA CasesupRootCA.crt -CAkey CasesupRootCA.pem -set_serial 01 -out CasesupClient.crt
Step 3:Create PFX file to use HTTPS request
#openssl pkcs12 -export -out CasesupClient.pfx -inkey CasesupClient.key -in CasesupClient.crt
