A Cypherpunk's Manifesto
|
||
|
by Eric Hughes
|
||
|
|
||
|
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.
