  • (2019-02-09) Scott Grayban: All this extension does is sends a query to www.sslchecker.com -- kinda sloppy IMHO.
  • (2017-11-10) Zere Bruin: Excellent extension that provides detail information on SSL certificates as well as the server that a website runs on, something that Chromium lacks. Doesn't cache results, so one has to wait a bit every time a certificate is re-checked.

  • (2017-11-30, v:0.1) Quintin Beukes: MITM Attack Not Detected
    I noticed SSL Checker uses sslchecker.com to fetch the certificate details. One use case for your fantastic extension is to be able to easily see who issued a certificate to protect myself against MITM attacks. Though in a MITM scenario sslchecker.com will see a different certificate than the one sent to the browser. Some of the networks I work on uses MITM for deep inspection of HTTPS traffic, and the SSL Checker completely misses this, showing a different certificate's information than the one used by my browser (because sslchecker fetches from the destination host, and the browser received it's certificate from a transparent proxy, eg. Websense) Please e-mail me on [email protected] then I can explain more and send screenshots. The community needs a chrome extension that will make it easy to detect whether an SSL connection is truly a secret. Your extension seemed to be the closest to this, but it doesn't give an accurate indication of the SSL session established between the server and browser. And Chrome's built in certificate views requires too many clicks to access this critical information. A simple toolbar button to see the SSL details in use would be ideal.
