According to Wall Street Journal n Yahoo! will release a plug-in based on Open PGP for end-to-end encryption of its emails by the end of 2015.
The company's goal is to make the use of PGP encryption accessible to every user and not just to the experts.
The plugin is described on the Purple blog Palace by Chief Information Security Officer Alex Stamos. The email encryption code was first unveiled at South by Southwest (SXSW) over the weekend.
Alex Stamos says Yahoo is currently "already distributing the source code to the public so that it can get feedback from the wider security industry." The current version has already been published in GitHub.
The code is already covered by the bug bounty of Yahoo, and Alex Stamos says the company hopes other email providers will follow suit. Google is already planning something for Chrome.
The Wall Street Journal also reports that Stamos reminded SXSW attendees that encryption of the content will not protect users from metadata collectors, but at least they will be encrypted.
