I do have private key(my_ca.key) and public key(my_cert.crt) which is signed by DigiCert. Now I want to generate the SSL certificate (version 3) and sign it by my private ke
I have got a simple solution for this problem.
Select the certificate in keychain right click it. There you will see the option "GetInfo" click it and select "Trust" option. Select the option When using this certificate to "Always trust". That's all - this certificate will be marked as trusted for your account.
