How does this kind of SSL work?

"Issued to" and "Domain Name" doesn't match but still valid and accepted by all major browsers without any warning.

While previewing my blog post in Blogger, I noticed that my blog was previewed via SSL. When I checked the certificate information, I noticed that "Issued To" and "Domain Name" didn't match. Here's a screenshot.

Domain name was techronak.blogspot.com but SSL certificate was issued to *.googleusercontent.com and the best thing was my browser (Chromium) didn't issue any kind of SSL warning.

How does this kind of SSL Certificates work?

Solution 1:

Look closely at the certificate:
