A Cypherpunk’s Manifesto

Privacy is necessary for an open society in the electronic age. Privacy is not secrecy. A private matter is something one doesn’t want the whole world to know, but a secret matter is something one doesn’t want anybody to know. Privacy is the power to selectively reveal oneself to the world.

If two parties have some sort of dealings, then each has a memory of their interaction. Each party can speak about their own memory of this; how could anyone prevent it? One could pass laws against it, but the freedom of speech, even more than privacy, is fundamental to an open society; we seek not to restrict any speech at all. If many parties speak together in the same forum, each can speak to all the others and aggregate together knowledge about individuals and other parties. The power of electronic communications has enabled such group speech, and it will not go away merely because we might want it to.

Since we desire privacy, we must ensure that each party to a transaction have knowledge only of that which is directly necessary for that transaction. Since any information can be spoken of, we must ensure that we reveal as little as possible. In most cases personal identity is not salient. When I purchase a magazine at a store and hand cash to the clerk, there is no need to know who I am. When I ask my electronic mail provider to send and receive messages, my provider need not know to whom I am speaking or what I am saying or what others are saying to me; my provider only need know how to get the message there and how much I owe them in fees. When my identity is revealed by the underlying mechanism of the transaction, I have no privacy. I cannot here selectively reveal myself; I must always reveal myself.

Therefore, privacy in an open society requires anonymous transaction systems. Until now, cash has been the primary such system. An anonymous transaction system is not a secret transaction system. An anonymous system empowers individuals to reveal their identity when desired and only when desired; this is the essence of privacy.

Privacy in an open society also requires cryptography. If I say something, I want it heard only by those for whom I intend it. If the content of my speech is available to the world, I have no privacy. To encrypt is to indicate the desire for privacy, and to encrypt with weak cryptography is to indicate not too much desire for privacy. Furthermore, to reveal one’s identity with assurance when the default is anonymity requires the cryptographic signature.

We cannot expect governments, corporations, or other large, faceless organizations to grant us privacy out of their beneficence. It is to their advantage to speak of us, and we should expect that they will speak. To try to prevent their speech is to fight against the realities of information. Information does not just want to be free, it longs to be free. Information expands to fill the available storage space. Information is Rumor’s younger, stronger cousin; Information is fleeter of foot, has more eyes, knows more, and understands less than Rumor.

We must defend our own privacy if we expect to have any. We must come together and create systems which allow anonymous transactions to take place. People have been defending their own privacy for centuries with whispers, darkness, envelopes, closed doors, secret handshakes, and couriers. The technologies of the past did not allow for strong privacy, but electronic technologies do.

We the Cypherpunks are dedicated to building anonymous systems. We are defending our privacy with cryptography, with anonymous mail forwarding systems, with digital signatures, and with electronic money.

Cypherpunks write code. We know that someone has to write software to defend privacy, and since we can’t get privacy unless we all do, we’re going to write it. We publish our code so that our fellow Cypherpunks may practice and play with it. Our code is free for all to use, worldwide. We don’t much care if you don’t approve of the software we write. We know that software can’t be destroyed and that a widely dispersed system can’t be shut down.

Cypherpunks deplore regulations on cryptography, for encryption is fundamentally a private act. The act of encryption, in fact, removes information from the public realm. Even laws against cryptography reach only so far as a nation’s border and the arm of its violence. Cryptography will ineluctably spread over the whole globe, and with it the anonymous transactions systems that it makes possible.

For privacy to be widespread it must be part of a social contract. People must come and together deploy these systems for the common good. Privacy only extends so far as the cooperation of one’s fellows in society. We the Cypherpunks seek your questions and your concerns and hope we may engage you so that we do not deceive ourselves. We will not, however, be moved out of our course because some may disagree with our goals.

The Cypherpunks are actively engaged in making the networks safer for privacy. Let us proceed together apace.

Onward.


Eric Hughes kiáltványa körülbelül egy évvel a cypherpunks csapat első találkozója után született. Bár a szöveg nem kezdődik olyan erősen, mint May „kísértet járja be Európát” parafrázisa, de nagy igényeket és nagy ígéreteket ír le. Megjelenése után sokan felkapták a kiáltványt, rivaldafénybe állítva a csoportot. Például a kiáltvány 1993-as megjelenését követően születtek a Wired, a Village Voice és a Whole Earth Review-ban a cypherpunkokról szóló cikkei. Az erős szöveg választ is provokált, Bram Cohenét, a Bittorrent atyjáét hamarosan ki is rakjuk.

The Crypto Anarchist Manifesto

A specter is haunting the modern world, the specter of crypto anarchy.

Computer technology is on the verge of providing the ability for individuals and groups to communicate and interact with each other in a totally anonymous manner. Two persons may exchange messages, conduct business, and negotiate electronic contracts without ever knowing the True Name, or legal identity, of the other. Interactions over networks will be untraceable, via extensive re- routing of encrypted packets and tamper-proof boxes which implement cryptographic protocols with nearly perfect assurance against any tampering. Reputations will be of central importance, far more important in dealings than even the credit ratings of today. These developments will alter completely the nature of government regulation, the ability to tax and control economic interactions, the ability to keep information secret, and will even alter the nature of trust and reputation.

The technology for this revolution—and it surely will be both a social and economic revolution—has existed in theory for the past decade. The methods are based upon public-key encryption, zero-knowledge interactive proof systems, and various software protocols for interaction, authentication, and verification. The focus has until now been on academic conferences in Europe and the U.S., conferences monitored closely by the National Security Agency. But only recently have computer networks and personal computers attained sufficient speed to make the ideas practically realizable. And the next ten years will bring enough additional speed to make the ideas economically feasible and essentially unstoppable. High-speed networks, ISDN, tamper-proof boxes, smart cards, satellites, Ku-band transmitters, multi-MIPS personal computers, and encryption chips now under development will be some of the enabling technologies.

The State will of course try to slow or halt the spread of this technology, citing national security concerns, use of the technology by drug dealers and tax evaders, and fears of societal disintegration. Many of these concerns will be valid; crypto anarchy will allow national secrets to be trade freely and will allow illicit and stolen materials to be traded. An anonymous computerized market will even make possible abhorrent markets for assassinations and extortion. Various criminal and foreign elements will be active users of CryptoNet. But this will not halt the spread of crypto anarchy.

Just as the technology of printing altered and reduced the power of medieval guilds and the social power structure, so too will cryptologic methods fundamentally alter the nature of corporations and of government interference in economic transactions. Combined with emerging information markets, crypto anarchy will create a liquid market for any and all material which can be put into words and pictures. And just as a seemingly minor invention like barbed wire made possible the fencing-off of vast ranches and farms, thus altering forever the concepts of land and property rights in the frontier West, so too will the seemingly minor discovery out of an arcane branch of mathematics come to be the wire clippers which dismantle the barbed wire around intellectual property.

Arise, you have nothing to lose but your barbed wire fences!


A szöveget a Cypherpunks lista egyik vezéralakja Timothy C. May írta 1988-ban. Először a Crypto ’88 konferencián olvasta fel, majd később az 1989-es és ’90-es Hackers konferencián is beszélt a titkosítós szép új világról. A szöveg aztán előkerült 1992-ben a Cypherpunks alapítógyűlésén is. Tegyük gyorsan hozzá, a csoportnak volt saját kiálványa is, amit Eric Hughes írt, az a holnapi program.

Adott pillanatban jó ötletnek tűnt: cypherpunkok

A cypherpunkok a kedvenc csoportom a kilencvenes évekből. Főleg azért, mert képes vagyok eltekinteni attól, hogy a kriptoanarchista jövőben bárki vehetne magának a vaterán bérgyilkost. Vagy legalábbis a csoport leghangosabb tagját, Timonthy C. May-t nem zavarná, ha vehetne, valamelyik fiókjában talán még a kód is megvan egy gyilkosbérlő szolgáltatáshoz.

A kilencvenes évek elején minden adott volt ahhoz, hogy beszédtéma legyen a polgári használatú titkosítás, a polgári szabadságjogok és az, hogy mennyire kell szabadjára engedni a rendőröket és a titkosszolgákat. Pont kilencvenben lezajlott az Operation Sundevil, aminek keretében megpróbáltak egy csapat hackert begyűjteni egy ellopott AT&T dokumentum miatt. A razziára válaszul megszületett az Electronic Frontier Foundation, a visszanézve nagy csinnadrattával előadott kisszerű eseményeket pedig megírta Bruce Sterling a Hacker Crackdownban.

A kilencvenes évek elején született meg a katonai erősségű brutálisan erős, értelmes idő alatt feltörhetetlen titkosítást kínáló Pretty Good Privacy is. A szoftver hamarosan megtalálta az útját az Egyesült Államokon kívülre, a program alkotója ellen pedig vizsgálat indult, mert a 40 bitnél hosszabb kulcsot használó rejtjelek exporttilalom alá estek. Így vetült Philip Zimmermannra a fegyverkereskedelem gyanúja.

És persze a kilencvenes évek elején támadt az NSA-nek az a remek ötlete, hogy biztonságos, lehallgatástól védett telefont ad az amerikai állampolgárok kezébe. A Clipper chippel felszerelt készülékek tulajdonosai annak biztos tudatában beszélhették meg ügyeiket, hogy kizárólag az NSA tud belehallgatni a társalgásba. A kulcs letéten (key escrow) alapuló megoldás természetesen nem tetszett a szakembereknek, gyorsan ki is derítették, hogy a clipperes titkosítás viszonylag egyszerűen törhető.

Az elérhető erős titkosításra épülő új világban hívők a Cypherpunks - illetve részben a Codepunks - levelezőlistán gyülekeztek. Felkerültek a Wired magazin második számának borítójára, a csoportról Steven Levy írta a cikket. Pár héttel később szerepeltek a Village Voice-ban és a Whole Earth Review-ben is. A szekér elindult.

A Clipper mellett ezer téma foglalkoztatta a csoport tagjait. Volt szó lenyomozhatatlan, a fizikai mivoltában létező pénz minden hasznos tulajdonságával rendelkező, erős titkosítással létrehozott fizetőeszközökről, adatkikötőkről, orgyilkos piacokról, adóelkerülésről, kemény matematikai problémákról és azok elegáns programozásbeli megoldásairól. A végtelen flameháborúk közepette egy olyan világ készült, ami sosem köszöntött be, amit ma legjobban talán Stephenson A nagy Simoleon botrány novellája alapján lehet elképzelni.

Aztán a Clipper elbukott, a vizsgálat befejeztével Zimmermann piacra lépett a PGP-vel, és - ahogy Clay Shirky írja 2003-as visszatekintő cikkében - a kormány rájött, hogy az emberek igazából nem akarják titkosítani a beszélgetéseiket. Ezzel nagyjából vége is volt a dalnak. Az évtized szólhatott volna a privacy-ről, de nem tette. Az ezerféle makacs emberből összeálló lista egészen sokáig húzta, a birkatürelmű John Gilmore-nak 1997-ben lett elege belőlük, ekkor hagyott fel a Cypherpunks lista hosztolásával, ám a továbbköltöző csapat még évekig levelezgetett. 2001-ből még lehet találni CP levelezést, de az már tényleg csak az árnya volt az eredeti listának.

A csoport nézeteit a May által szerkesztett Cyphernomicon foglalja össze legjobban. A dokumentum brutálisan hosszú, sima formázás nélküli szövegben is több mint egy megabájt - az Ulysses másfél, Joyce nyert - cserébe bődületesen redundáns is. Beleolvasni viszont mindenképpen ajánlott. A kevéssé tágtűrésű olvasók a True nyms and crypto anarchy című sokkal rövidebb May írással próbálkozhatnak.

Kriptoanarchista álom kezdődik

Introduction to BlackNet

Your name has come to our attention. We have reason to believe you may be interested in the products and services our new organization, BlackNet, has to offer.

BlackNet is in the business of buying, selling, trading, and otherwise dealing with information in all its many forms.

We buy and sell information using public key cryptosystems with essentially perfect security for our customers. Unless you tell us who you are (please don’t!) or inadvertently reveal information which provides clues, we have no way of identifying you, nor you us.

Our location in physical space is unimportant. Our location in cyberspace is all that matters. Our primary address is the PGP key location: „BlackNet <nowhere@cyberspace.nil>” and we can be contacted (preferably through a chain of anonymous remailers) by encrypting a message to our public key (contained below) and depositing this message in one of the several locations in cyberspace we monitor. Currently, we monitor the following locations: alt.extropians, alt.fan.david-sternlight, and the „Cypherpunks” mailing list.

BlackNet is nominally nondideological, but considers nation-states, export laws, patent laws, national security considerations and the like to be relics of the pre-cyberspace era. Export and patent laws are often used to explicity project national power and imperialist, colonialist state fascism. BlackNet believes it is solely the responsibility of a secret holder to keep that secret—not the responsibilty of the State, or of us, or of anyone else who may come into possession of that secret. If a secret’s worth having, it’s worth protecting.

BlackNet is currently building its information inventory. We are interested in information in the following areas, though any other juicy stuff is always welcome. „If you think it’s valuable, offer it to us first.”

  • trade secrets, processes, production methods (esp. in semiconductors)
  • nanotechnology and related techniques (esp. the Merkle sleeve bearing)
  • chemical manufacturing and rational drug design (esp. fullerines and protein folding)
  • new product plans, from children’s toys to cruise missiles (anything on „3DO”?)
  • business intelligence, mergers, buyouts, rumors

BlackNet can make anonymous deposits to the bank account of your choice, where local banking laws permit, can mail cash directly (you assume the risk of theft or seizure), or can credit you in „CryptoCredits,” the internal currency of BlackNet (which you then might use to buy _other_ information and have it encrypted to your special public key and posted in public place).

If you are interested, do NOT attempt to contact us directly (you’ll be wasting your time), and do NOT post anything that contains your name, your e-mail address, etc. Rather, compose your message, encrypt it with the public key of BlackNet (included below), and use an anonymous remailer chain of one or more links to post this encrypted, anonymized message in one of the locations listed (more will be added later). Be sure to describe what you are selling, what value you think it has, your payment terms, and, of course, a special public key (NOT the one you use in your ordinary business, of course!) that we can use to get back in touch with you. Then watch the same public spaces for a reply.

(With these remailers, local PGP encryption within the remailers, the use of special public keys, and the public postings of the encrypted messages, a secure, two-way, untraceable, and fully anonymous channel has been opened between the customer and BlackNet. This is the key to BlackNet.)

A more complete tutorial on using BlackNet will soon appear, in plaintext form, in certain locations in cyberspace.

Join us in this revolutionary—and profitable—venture.
