PKI Tutorials - Herong's Tutorial Examples - v2.34, by Herong Yang
Exporting Server Certificate to File in Mozilla Firefox
This section provides a tutorial example on how to export an HTTPS server certificate to a certificate file in PEM (Privacy Enhanced Mail) format.
In previous tutorials, I learned how to view an HTTPS server certificate and its certificate chain. Now I want to learn how to save a server certificate to a certificate file.
1. Visit https://login.yahoo.com with Firefox, and open the server certificate again as shown in the previous tutorial.
2. Scroll down to the Miscellaneous section. I see 2 download links: "PEM (cert)" and "PEM (chain)".
3. Click "PEM (cert)". The selected certificate will be exported to a certificate file in PEM format in the download directory.
4. Click "PEM (chain)". The entire certificate chain will be exported to a certificate file in PEM format in the download directory.
If you are using an older version, Firefox uses a dialog box to display the HTTPS server certificate with two tabs: "General" and "Details". The server "Export" function is accessible in the "Details" tab as shown below:
The older version also gives you the option to export the certificate into different file formats:
X.509 Certificate (PEM) (*.crt,*.pem) X.509 Certificate with chain (PEM) (*.crt,*.pem) X.509 Certificate (DER) (*.der) X.509 Certificate (PKCS#7) (*.p7c) X.509 Certificate with chain (PKCS#7) (*.p7c)
