  • (2018-06-11) Nuclear Squid!!: I just discovered Mailvelope also works in NextCloud's mail plugin! Amazing. (just add your Nextcloud instance's domain to the rules for webmail providers.) Very easy to use extension for enabling end-to-end encryption. If Google *really* wanted to protect peoples' privacy this would be the way to do it. They should fund development of this plugin, drive its adaptation to all major browsers and webmail clients, and help usher in an era of end-to-end encryption where everyone's grandmother can use PGP as easily as doing a cut-and-paste :P OK I should wake up now. :/
