Google is taking another step towards an internet that can stand up to snooping from the NSA. On Tuesday, the company released the source code for a new web browser plugin that encrypts your email messages before they’re sent across the net. Dubbed End-to-End, the plugin aims to prevent interlopers from reading messages even if they gain access to the computer servers that drive your web email service of choice. So, if you’re using Googles’s Gmail, it could thwart the NSA and other snoopers even if they have access to Google’s network. The plugin isn’t yet available to the general public. The idea is for security researchers to heavily test the code before Google releases a completed version of the plugin that’s available to everyone.
