∟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 chain. Now I want to learn how to save a server certificate to a certificate file.

1. Run Google Chrome and go to https://www.yahoo.com. Wait for the home page to be fully loaded.

2. Click the site information icon at the left side of the URL address area. I see the site information popup box.

3. Click "Connection is secure". I see the site security popup box.

4. Click the "Certificate is valid" link on the popup box. I see the server certificate displayed in the Certificate Viewer.

5. Since different Chrome releases may use different Certificate Viewers, you may have to navigate differently to export the server certificate. For example:

Click the "Export" button on the "Details" tab on Chrome 124,
Select the certificate icon and drag it to a folder on Chrome 103.
Click the "Copy to file" button on the "Details" tab on Chrome 40.

6. If the "Certificate Export Wizard" is showing up during the exporting process, you may see options for the certificate file format:

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)
