The Electronic Frontier Foundation (EFF) is a nonprofit public-interest
organization protecting rights and promoting liberty online. It was founded
in 1990 by Mitchell Kapor, John Perry Barlow, and John Gilmore.
<P>
The Foundation seeks to educate individuals, organizations, companies, and
governments about the issues that arise when computer and communications
technologies change the world out from under the existing legal and social
matrix.
<P>
The Foundation has been working on cryptography policy for many years. It
was a significant force in preventing the adoption of the "Clipper chip"
and its follow-on "key escrow" proposals, and continues to advocate for wide
public availability and use of uncompromised and unbreakable encryption
technology. EFF is backing the lawsuit in which Professor Daniel Bernstein
seeks to overturn the United States export laws and regulations on cryptography,
arguing that the First Amendment to the US Constitution protects his right
to publish his cryptography research results online without first seeking
government permission. EFF's research effort in creating this first publicly
announced DES Cracker, and the publication of its full technical details,
are part of EFF's ongoing campaign to understand, and educate

the public about, the social and technical implications of cryptographic
technology.

EFF encourages you to join us in exploring how our society can best respond
to today's rapid technological change. Please become an EFF member; see

John Gilmore is an entrepreneur and civil libertarian. He was an early employee
of Sun Microsystems, and co-founded Cygnus Solutions, the Electronic Frontier
Foundation, the Cypherpunks, and the Internet's "alt" newsgroups. He has
twenty-five years of experience in the computer industry, including programming,
hardware and software design, and management. He is a significant contributor
to the worldwide open sourceware (free software) development effort. His
advocacy efforts on encryption policy aim to improve public understanding
of this fundamental technology for privacy and accountability in open societies.
He is currently a board member of Moniker pty ltd, the Internet Society,
and the Electronic Frontier Foundation.
<P>
John leads the EFF's efforts on cryptography policy, managed the creation
of the DES cracker and wrote much of the text in this book.
