Obtaining Certificate Information through Chrome Extension

[Dallas Schoff]

Hello,

A team and I are attempting to obtain certificate information from a web browser through Javacript code in our Chrome extension and are wondering if this is possible. I have done some research into this topic and have found information like this and this which relate but do not provide a definite answer. Our motivation for needing this functionality is we are developing a chrome extension that will verify the authenticity a certificate. Information about the process we will be implementing can be found here.

Hi Dallas,

Have you checked this developer documentation:

Chrome: https://developer.chrome.com/docs/extensions/reference/certificateProvider/

Firefox: https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/webRequest/CertificateInfo

Thanks,

Stefan vd

Hi Stefan,

Is this available to me on an OS other than ChromeOS? I have seen another post saying that.

Best,

Dallas
