Back in june this year, Google announced an alpha Google Chrome extension called "End-to-End" for sending and receiving emails securely, in wake of former NSA contractor Edward Snowden’s revelations about the global surveillance conducted by the government law-enforcements.

 

Finally, the company has announced that it made the source code for its End-to-End Chrome extension open source via GitHub.

 

Google is developing a user-friendly tool for individuals to implement the tough encryption standard known asPretty Good Privacy (PGP) in an attempt to fully encrypt people’s Gmail messages that can’t even be read by Google itself, nor anyone else other than the users exchanging the emails.

 

PGP is an open source end-to-end encryption standard for almost 20 years, used to encrypt e-mail over the Internet providing cryptographic privacy and authentication for data communication, which makes it very difficult to break. But implementing PGP is too complicated for most of the people, therefore, the new tool was designed to make encryption easy.
