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.

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 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.

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

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.
