Google adds warning to unencrypted emails

Google has a pair of new security features that will warn users in cases when they should be cautious about revealing sensitive information over email.

Users will be shown a small red unlocked padlock icon in the upper right-hand corner of a message to let them know that someone they're sending messages to or receiving email from doesn't support TLS encryption that would keep information from prying eyes in transit. 

Odds are, the overwhelming majority of email that users see on a regular basis likely won't contain one of these warnings, as most major email providers like Microsoft and Yahoo already support TLS encryption.

But Google's move might pressure other email providers -- especially companies that run their own email servers -- to set up encryption in order to clear that check.
