Show information on certificates

It would be cool if DevUtilsApp had a feature to decode certificates. Nobody wants to paste private certificate keys into some random website and trying to remember the correct openssl command to decode a certificate is a pain in the behind.

Maybe you can leverage macOS's QLPreviewController which supports certificates.
