Edward Snowden sent Glenn Greenwald this video guide about encryption for journalists
Before Laura Poitras brought Glenn Greenwald into the story about former National Security Agency contractor Edward Snowden, Greenwald received messages from a mysterious contact calling himself Cincinnatus. The source urged Greenwald to learn how to protect his e-mail with encryption so he could receive sensitive information.
Cincinnatus reportedly even went so far as to send a video tutorial to Greenwald, walking him through the necessary steps to set up the added security measures. But Greenwald didn't bother to get with the program until after he was in Hong Kong and in deep discussions with Snowden, at which point he realized he may have missed out on the opportunity for another scoop by not following up with Cincinnatus.
The twist? Cincinnatus turned out to be Snowden. After Greenwald e-mailed Cincinnatus to let him know he'd finally set up encryption, Snowden revealed he was behind the correspondence all along.
