Now we have a bit more clarity on what Edward Snowden meant last week when he said, “The US government is not going to be able to cover this up by jailing or murdering me. Truth is coming, and it cannot be stopped.”
It turns out Snowden has given copies of the files he purloined from the US National Security Agency, his former employer, to “many different people around the world,” according to Glenn Greenwald, the Guardian journalist who first published some of the materials provided by Snowden. But the files are encrypted, so the people who have the documents can’t read them. “If anything happens at all to Edward Snowden, he told me he has arranged for them to get access to the full archives,” Greenwald told the Daily Beast.
How might that work? Snowden could be using any of a number of complicated cryptographic gambits.
Cryptography is a gatekeeper. It allows us to check our bank accounts, sign into email, and browse Facebook without worrying that any of that data can be intercepted by others (the NSA surveillance revealed by Snowden notwithstanding).
