Google initiates an unlocked/broken lock icon system in Gmail in honor of Safer Internet Day, showing whether or not emails are encrypted or not. Gmail email has been encrypted for some time. Not all other email services share this level of protection. Google's initiative - starting today - shows a tiny un-locked icon to the right of your "to" or "from" bar in any given email. This broken or unlocked lock indicates whether or not the person on the other end of your email works with a service that supports TLS encryption.
