Make sure that you have set up your browser to use the proxy as the HTTP and HTTPS proxy.
Request the file
cert.derfrom any domain via HTTP using the browser.
For example, you can use one of the following links:
The browser will download the certificate file. Depending on the configuration, the file will be either placed in the default download directory or in the directory of your choice.
Navigate to the browser settings. At the end of the settings list expand the additional settings by selecting the Advanced button.
Select the “Manage certificates” option.
A “Certificates” window will open, containing information about Chrome certificates. Switch to the “Trusted Root Certification Authorities” tab and select the Import button.
A Certificate Import Wizard should be opened. Select the Next button.
Select the Browse button and then choose the certificate file you downloaded earlier.
Choose “All files” file type if necessary. Select the Next button.
You will be asked to choose a certificate store. Select the option “Place all certificates in the following store” and set “Trusted Root Certification Authorities” as the store. Select the Next button.
Make sure that you have selected the appropriate store for the certificate and start the import process by selecting the Finish button.
You will be presented with a warning message about the inability to validate the fingerprint of the certificate being imported. Select the Yes button in order to complete the import process.
Given that the import is successsful, “The import was successful” informational message will appear.
Now you will see the imported certificate in the “Trusted Root Certification Authorities” tab of the “Certificates” window. Notice that the name and expiration date of your certificate will differ from those shown in the image.
Check that the certificate was installed correctly. To do that, go to any site via HTTPS. You should be redirected to the HTTPS version of the site without any warning messages about untrusted certificates.
For example, you could browse to the HTTPS version of the Google Gruyere site: https://google-gruyere.appspot.com
