WHEN EDWARD SNOWDEN leaked the biggest collection of classified National Security Agency documents in history, he wasn’t just revealing the inner workings of a global surveil­lance machine. He was also scrambling to evade it. To com­municate with the journalists who would publish his secrets, he had to route all his messages over the anonymity soft­ware Tor, teach reporters to use the encryption tool PGP by creating a YouTube tutorial that disguised his voice, and eventually ditch his comfortable life (and smartphone) in Hawaii to set up a cloak-and-dagger data handoff halfway around the world.

Now, nearly four years later, Snowden has focused the next phase of his career on solving that very specific instance of the panopticon problem: how to protect reporters and the people who feed them informa­tion in an era of eroding privacy—without requiring them to have an NSA analyst’s expertise in encryption or to exile them­selves to Moscow.
