Cryptographer Adi Shamir, the 'S' in RSA, once said that "cryptography is bypassed, not penetrated". In the light of the Snowden revelations about the NSA, various people have proposed using crypto in order to evade NSA surveillance. This talk tries to put that into perspective, looking at ten years of trying to secure things with crypto that ultimately failed, not through anyone bothering to break it but because it was much easier just to bypass it. The lesson from all of this is that you can't just throw crypto at something and assume that that will make you safe.
