Edward Snowden reportedly used Lavabit email address to invite people to a press conference in Moscow. Lavabit, which launched in 2004, specialized in providing a high-security email service. It was designed to thwart the kind of surveillance techniques that Snowden revealed in June were used by the U.S. government. Founder Ladar Levison wrote that he couldn’t describe the legal machinations under way. Levison: “I cannot share my experiences over the last six weeks, even though I have twice made the appropriate requests””]
