「手づくりの暗号化製品が、よく研究されたオープンソースのツールよりも優れている可能性はほとんどない」

“I think the reverse is true. I think this will help US intelligence efforts. Cryptography is hard, and the odds that a home-brew encryption product is better than a well-studied open-source tool is slight. Last fall, Matt Blaze said to me that he thought that the Snowden documents will usher in a new dark age of cryptography, as people abandon good algorithms and software for snake oil of their own devising. My guess is that this an example of that.”
