OpenSSL Viewing Certificates Exported from Firefox

This section provides a tutorial example on how to use OpenSSL to view contents of a certificate file exported from Firefox.

In the previous tutorial, we successfully exported the certificate from "VeriSign Class 3 Public Primary Certification Authority" to a DER file, \verisign3.crt. Now I want to view its contents with OpenSSL.

>openssl x509 -in \verisign3.crt -inform PEM -noout -text
Certificate:

Very nice.

Of course, we can export the certificate out of Firefox, and save it in other formats. Just select a different one from the supported file type list.
