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: the NSA just isn't that smart. Anything they know how to crack, you can be sure that terrorists and mobsters can get around too. Barbara had been one of the reporters who'd made her reputation from covering the issue. She'd cut her teeth covering the tail end of the civil rights movement in San Francisco, and she recognized the similarity between the fight for the Constitution in the real world and the fight in cyberspace. So she got it. I don't think I could have explained this stuff to my parents, but with Barbara it was easy. She asked smart questions about our cryptographic protocols and security procedures, sometimes asking stuff I didn't know the answer to -- sometimes pointing out potential breaks in our procedure. We plugged in the Xbox and got it online. There were four open WiFi nodes visible from the board room and I told it to change between them at random intervals. She got this too -- once you were actually plugged into the Xnet, it was just like being on the Internet, only some stuff was a little slower, and it was all anonymous and unsniffable. "So now what?" I said as we wound down. I'd talked myself dry and I had a terrible acid feeling from the coffee. Besides, Ange kept squeezing my hand under the table in a way that made me want to break away and find somewhere private to finish making up for our first fight. "Now I do journalism. You go away and I research all the things you've told me and try to confirm them to the extent that I can. I'll let you see what I'm going to publish and I'll let you know when it's going to go live. I'd prefer that you *not* talk about this with anyone else
