Exporting Server Certificate to File in Google Chrome

This section provides a tutorial example on how to export an HTTPS server certificate to a certificate file in PEM (Privacy Enhanced Mail) format, also called Base-64 encoded X.509 format.

In previous tutorials, I learned how to view an HTTPS server certificate and its certificate path. Now I want to learn how to save a server certificate to a certificate file.

1. Run Google Chrome and go to https://login.yahoo.com.

2. Click the lock icon at the left side of the URL address area. The page security dialog box shows up.

3. Click the "Certificate" link. The Certificate dialog box shows up.

5. Click the "Details" tab and click the "Copy to File..." button. The "Certificate Export Wizard" dialog box shows up.

6. Click the "Next" button. The Export File Format step shows up with these options:

Certificate can be exported in a variety of file formats.

Select the format you want to use:
   ( ) DER encoded binary X.509 (.CER)
   (.) Base-64 encoded X.509 (.CER)
   ( ) Cryptographic Message Syntax Standard
       - PKCS #7 Certificates (.P7B)
   ...

7. Select "Base-64 encoded X.509 (.CER)" as the export file format, and click the "Next" button. The File to Export step shows up.

8. Enter a file name: \temp\yahoo.cer, and click the "Next" button. The confirmation step shows up.

9. Click the "Finish" button. The Yahoo server certificate will be exported into the specified file.

The picture below shows you the export file format options in the Certificate Export Wizard:
