EXTRA: Bill Binney and Ladar Levison Talk Cryptography

This is the raw interview used in our episode "The Other Ed Snowdens" with William Binney and Ladar Levison. In that podcast episode we said the conversation got wonky and in the weeds so we cut out some of the most detailed debate about NSA surveillance and crystallographic options. Well, here is that part of the conversation.  If you missed that episode, give it a listen. Bill Binney worked for more than 30 years at the NSA and designed the architecture for programs the NSA later used to spy on American citizens. When he found out, he quit the agency and went public about it. Call him the pre-Snowden NSA whistleblower.  Ladar Levison ran the secure email program Ed Snowden used to communicate with Glenn Greenwald and Laura Poitras. When the FBI came to him asking for the keys to the encryption he decided to shut down his company rather than comply. That dramatic story is told in our episode "When the FBI Knocks."
