Cryptonomicon by Neal Stephenson

jumping to his feet in the middle of meals or conversations and going out for solitary walks. This was partly to keep himself from saying something undiplomatic, and partly as a childish but fruitless tactic to get the attention he craved from Charlene.
    He knew the whole poster saga was going to be a disaster from early on. He kept warning Charlene and the others. They listened coolly, clinically, as if Randy were a test subject on the wrong side of a one-way mirror.
     
    Randy forces himself to stay awake long enough for it to get dark. Then he lies in bed for a few hours trying to sleep. The container port is just north of the hotel, and all night long, Rizal Boulevard, along the base of the old Spanish wall, is jammed from one end to the other with container-carrying semis. The whole city is a cauldron of internal combustion. Manila seems to have more pistons and exhaust pipes than the rest of the world combined. Even at two in the morning the hotel’s seemingly unshakable mass hums and rattles from the seismic energy pouring from all of those motors. The noise detonates car alarms down in the hotel’s lot. The noise of one alarm triggers others, and so on. It is not the noise that keeps Randy awake so much as the insane stupidity of this chain reaction. It is an object lesson: the kind of nightmarish, snowballing technological fuck-up that keeps hackers awake at night even when they can’t hear the results.
    He paws open a Heineken from his minibar and stands in front of the window, looking. Many of the trucks are adorned with brilliant displays of multicolored lights—not quite as flashy as those of the few jeepneys that scurry and jostle among them. Seeing so many people awake and working puts sleep out of the question.
    He is too jet-lagged to accomplish anything that requires actual thought—but there is one important job he can do, which requires no thinking whatsoever. He starts up his laptop again. Seeming to levitate in the center of his dark room, the screen is a perfect rectangle of light the color of diluted milk, of a Nordic dawn. This light originates in small fluorescent tubes imprisoned in the polycarbonate coffin of his computer’s display. It can only escape through a pane of glass, facing Randy, which is entirely covered by small transistors arranged in a grid, which let photons through, or don’t, or let through only those of a particular wavelength, cracking the pale light into colors. By turning those transistors on and off according to some systematic plan, meaning is conveyed to Randy Waterhouse. A good filmmaker could convey a whole story to Randy by seizing control of those transistors for a couple of hours.
    Unfortunately, there are a lot more laptop computers floating around than there are filmmakers worth paying attention to. The transistors are almost never put into the hands of human beings. They are controlled, instead, by software. Randy used to be fascinated by software, but now he isn’t. It’s hard enough to find human beings who are interesting.
    The pyramid and the eyeball appear. Randy spends so much time using Ordo now that he has his machine boot it up automatically.
    Nowadays the laptop has only one function for Randy: he uses it to communicate with other people, through e-mail. When he communicates with Avi, he has to use Ordo, which is a tool for taking his ideas and converting them into streams of bits that are almost indistinguishable from white noise, so that they can be sent to Avi in privacy. In exchange, it receives noise from Avi and converts it into Avi’s thoughts. At the moment, Epiphyte has no assets other than information—it is an idea, with some facts and data to back it up. This makes it eminently stealable. So encryption is definitely a good idea. The question is: how much paranoia is really appropriate?
    Avi sent him encrypted e-mail:
     
    When you get to Manila I would like you to generate a 4096-bit key pair and keep it on a floppy disk that you
