I recently attended RSA and had a chance to see the cryptography panel. Towards the end of the panel an amusing amount of bickering began between the former NSA technical director (Brian snow) and folks such as Whit Diffie (inventor of diffie hellman key exchange), and Adi Shamir (co founder of RSA algorithm) about what the NSA knows versus the private sector.

RSA has posted a copy of the video below for your viewing pleasure.
