Keychain Certificates

Drag the certificate you copied to the desktop into the list of certificates. After localhost gets added to the System keychain, double-click it to open it again. Expand the Trust section and for the first option, pick Always Trust.

In the Keychain Access app on Mac, select a keychain, then click either the My Certificates category or the Certificates category to see the certificates in that keychain. Select the certificate you want to view, then click the Info button in the toolbar.

If you run into this error, it can be due to various reasons. For example, your browser might be using an outdated version of SSL, or a firewall might be interfering with the certificate. Alternatively, the certificate might not have been configured properly.

One possible cause of this error is that a self-signed certificate is installed on the server. Self-signed certificates aren't trusted by browsers because they are generated by your server, not by a CA. You can tell if a certificate is self-signed if a CA is not listed in the issuer field in our SSL Certificate tester.

In WHM the Private keys are stored along with the corresponding CSRs and certificates in “SSL Storage manager”.
