Little Brother

told me about your friend Darryl and the note you showed me. I can see how it would be a good adjunct; I could pitch this as the origin of the Xnet. 'They made an enemy they'll never forget,' that sort of thing. But to be honest, I'd rather not have to tell that story if I don't have to.
    "I'd rather have a nice clean tale about the secret prison on our doorstep, without having to argue about whether the prisoners there are the sort of people likely to walk out the doors and establish an underground movement bent on destabilizing the federal government. I'm sure you can understand that."
    I did. If the Xnet was part of the story, some people would say, see, they need to put guys like that in jail or they'll start a riot.
    "This is your show," I said. "I think you need to tell the world about Darryl. When you do that, it's going to tell the DHS that I've gone public and they're going to go after me. Maybe they'll figure out then that I'm involved with the Xnet. Maybe they'll connect me to M1k3y. I guess what I'm saying is, once you publish about Darryl, it's all over for me no matter what. I've made my peace with that."
    "As good be hanged for a sheep as a lamb," she said. "Right. Well, that's settled. I want the two of you to tell me everything you can about the founding and operation of the Xnet, and then I want a demonstration. What do you use it for? Who else uses it? How did it spread? Who wrote the software? Everything."
    "This'll take a while," Ange said.
    "I've got a while," Barbara said. She drank some coffee and ate a fake Oreo. "This could be the most important story of the War on Terror. This could be the story that topples the government. When you have a story like this, you take it very carefully."

Chapter

    This chapter is dedicated to Waterstone's, the national UK bookselling chain. Waterstone's is a chain of stores, but each one has the feel of a great independent store, with tons of personality, great stock (especially audiobooks!), and knowledgeable staff.

    So we told her. I found it really fun, actually. Teaching people how to use technology is always exciting. It's so cool to watch people figure out how the technology around them can be used to make their lives better. Ange was great too — we made an excellent team. We'd trade off explaining how it all worked. Barbara was pretty good at this stuff to begin with, of course.
    It turned out that she'd covered the crypto wars, the period in the early nineties when civil liberties groups like the Electronic Frontier Foundation fought for the right of Americans to use strong crypto. I dimly knew about that period, but Barabara explained it in a way that made me get goose-pimples.
    It's unbelievable today, but there was a time when the government classed crypto as a munition and made it illegal for anyone to export or use it on national security grounds. Get that? We used to have illegal math in this country.
    The National Security Agency were the real movers behind the ban. They had a crypto standard that they said was strong enough for bankers and their customers to use, but not so strong that the mafia would be able to keep its books secret from them. The standard, DES-56, was said to be practically unbreakable. Then one of EFF's millionaire co-founders built a 250,000 DES-56 cracker that could break the cipher in two hours.
    Still the NSA argued that it should be able to keep American citizens from possessing secrets it couldn't pry into. Then EFF dealt its death-blow. In 1995, they represented a Berkeley mathematics grad student called Dan Bernstein in court. Bernstein had written a crypto tutorial that contained computer code that could be used to make a cipher stronger than DES-56. Millions of times stronger. As far as the NSA was concerned, that made his article into a weapon, and therefore unpublishable.
    Well, it may be hard to get a judge to understand crypto and what it means, but it turned out that the average Appeals Court judge isn't real enthusiastic about telling grad students what kind of articles they're allowed to write. The crypto wars ended with a victory for the good guys when the 9th Circuit Appellate Division Court ruled that code was a form of expression protected under the First Amendment — "Congress shall make no law abridging the freedom of speech." If you've ever bought something on the Internet, or sent a secret message, or checked your bank-balance, you used crypto that EFF legalized. Good thing, too:
