Starting this month, Chrome users are going to start seeing a lot more sites flagged as insecure. Google is firmly on the technologist side of the encryption war, and it wants to make encryption something regular people care about. Why?
Not using encryption is like sending everything you visit/everything you do, scrawled upon postcards, with stops in all sorts of places, passing by people you would not want seeing everything.
Google is going to start by complaining (loudly) when you visit an unencrypted page that has a credit card field or a password. While most e-commerce sites that collect credit cards are using SSL, a huge number of sites running Drupal or WordPress or Joomla do not. Including yours?
