Q: How do I get MIT personal certificates using the Google Chrome browser?

On this page:

Context

  • Google Chrome is a web browser for PC, Mac, or Linux
  • IS&T does not support Google Chrome

Answer

On Windows and Mac, Google Chrome uses the native certificate store of the operating system. This means that Google Chrome on Windows will use the certificates that Internet Explorer uses, and Google Chrome on Mac OS X will use the certificates that Safari uses. Thus, to use certificates, install them for the native browser for that operating system.

On Linux, Google Chrome uses a native certificate store that is not widely shared. However, getting certificates for Chrome on Linux is straightforward: get them from http://ca.mit.edu/

Installation

Mac OS X and Windows

Linux

To use certificates in Google Chrome installed on Windows, go to http://ca.mit.edu/ and follow the steps in the web forms - it works much like Firefox.

  1. Download the MIT Certificate Authority (MIT CA) the link on the final page
  2. Go to the Wrench menu > Preferences
  3. Choose Under the Hood, then click the button for Manage Certificates
  4. Go to the Authorities tab and press the button for Import...
  5. Find the mitca.crt from your download folder and Open it to import it into Chrome.
  6. If you are asked to Edit trust settings, choose Trust this certificate for identifying web sites.

    These installation instructions no longer work in Chrome for Linux either, since Chrome’s builtin support for key generation was removed in Chrome 57.

    The official IS&T recommentation is to download and install their custom CertAid utility on supported platforms, or to get your certificate in Firefox and import it.

    If you don’t want to install separate software or use a different browser, you can use SIPB’s CertAssist service to get your personal certificate directly in Chrome. CertAssist is a web application that doesn’t require any installation; all cryptography is performed in client-side JavaScript. Simple instructions for Windows, Mac, Linux, and Android are given on the page.
