SSL Certificates WhoisGuard PremiumDNS CDN NEW VPN UPDATED ID Validation NEW 2FA Public DNS. And in this case, the certificate is designated as a CA certificate; meaning, it can be used to issue (sign and verify) other certificates. In order to enable the client to connect with the Server, we need to register the Root certificate (created in step 3.4) at the Windows machine from where the Client will access the Server. This is just the key but we should generate a Certificate Sing Request CSR to the CA which is we in this example. SHA-256 is the default in later versions of OpenSSL, but earlier versions might use SHA-1. This guide demonstrates how to act as your own certificate authority (CA) using the OpenSSL command-line tools.
