On Tuesday, Google announced they are creating a Chrome plug-in that will allow users to encrypt their emails in full, regardless of the recipient. In their online Transparency Report, Google made it abundantly clear which email providers support encryption, and which do not. They based this on the 425 million active Gmail users and found about half of email traffic is not private. The Transparency Report allows users to search by region to find out if their email provider is using encryption. Think of encrypted email as sending a locked box, where only the sender and receiver have the key.
