Lots of people working in cryptography have no deep concern with real application issues. They are trying to discover things clever enough to write papers about.

I think that the people who are trying to shut down WikiLeaks are going to have to accept this as a fact of reality that cryptography allows you to do this kind of thing.

Without strong encryption, you will be spied on systematically by lots of people.

I thought cryptography was a technique that did not require your trusting other people-that if you encrypted your files, you would have the control to make the choice as to whether you would surrender your files.

I understood the importance in principle of public key cryptography but it's all moved much faster than I expected. I did not expect it to be a mainstay of advanced communications technology.

People are leaving trails everywhere they go; automated web crawlers tell you an awful lot about their social activities. The flow of information in fundamentally unobtrusive ways into social control organisations has risen dramatically.
