How to make Chrome on OS X trust a self-signed certificate

When setting up Subversion recently to use with my various JDeveloper and NetBeans installations here, there and everywhere, I wanted to browse my repositories from Chrome (my main day to day browser) on Mac OS X (my main day to day OS).  But, my Subversion installation is using HTTPS with a self-signed certificate, so I had to tell Chrome how to understand it.

The process is as follows:

  • Open the offending site in Chrome
  • Click on little bang icon at the right hand end of the address bar
  • Hold down the Option key and drag the certificate from the popup dialog to the desktop
  • Rename it with a .cer extension
  • In the Chrome menu, navigate to Preferences, Under the Hood, Security, Manage Certificates
  • Click on the plus “+” icon to add a certificate
  • Point to the .cer file on the desktop
  • Select the option to trust the certificate

That’s it, all done!
