I recently upgraded my smartphone (from Samsung Note II running KitKat to Samsung Note 5 running Lollipop).

The new phone uses Google Chrome Browser version 46.0.2490.76 and it is great, EXCEPT I cannot figure out how to view a site's certificate details when the padlock is not green. For example, visit http://www.papajohns.com -- this will redirect to an https:// site, but the https:// will not be green or red and hence there is no option to click for details (see image: (http://imgur.com/xjpXmMN)

The previous phone (like my other browsers) will allow me to inspect the TLS/SSL certificates (hash values, chain of trust, etc. as well as the negotiated connection details [RSA vs ECC, AES256 vs etc.)

How do I do this in Google Chrome mobile on Lollipop?

Click on Green Padlock symbol in navigation bar next to URL, click on Details and click on Certificate Information to view the Connection details.

You can also view DigiCert SHA2 CA, High Assurance CA in the drop-down under certificate viewer.

EDIT:

For HTTPS websites without a Green padlock, Chrome will give an error saying Your connection is not private if you're visiting the site for the first time and you can click on the Red Padlock -> Details -> Certificate Information.

Also, if you're not getting the Red padlock when you visit the page, that's because you've clicked on Proceeed to Webiste, I understand the risks.

To get back that Red padlock you have to Clear cookies. To do that, Chrome → Settings → Privacy → Clear Browsing data → Clear Cookies and site data.

  • Hi, thanks I forgot to mention that I'm looking for the case where the padlock is not green (e.g. papajohns.com) – digitale Nov 1 '15 at 7:10

  • I tried clearing the cookies, cache and site data, but it still doesn't work. Try to visit papajohns.com It will redirect to an https site. The URL says https, there is no error but there is also no green or red icon. I do see the green icon with websites that use an extended validation certificate. – digitale Nov 2 '15 at 3:57
  • I added an image to show what I am seeing, even after clearing the browser cache, cookies, and site data. – digitale Nov 2 '15 at 4:11
  • @digitale After clearing cache Goto https:// papajohns.com instead of https:// www.papajohns.com you'll be able to see the certificates – Manubhargav Nov 2 '15 at 4:30
