They Thought They Were Free
by mrm＠netcom.com 17 Dec '03

17 Dec '03

As long as we're on the subject of recommending books ... a great one is Milton Mayer's "They Thought They Were Free", interviews with ten Germans post-war. The title pretty much sums it up. Mayer was an excellent writer and journalist. The book is hard to find. title: "they thought they were free: the germans, 1933-45" author: milton mayer University of Chicago Press, 1955 ISBN 0-226-51190-1 (cloth) ISBN 0-226-51192-8 (paper) Library of Congress Catalog Card Number 55-5137 One quote at the beginning of the book: The Pharisee stood and prayed thus with himself "God, I thank Thee, that I am not as other men are." Here's hoping cypherpunks don't start echoing that sentiment ... Marianne

Crypto anarchist getting through customs

Given that most points of entry are >under-staffed, there's not much else they can do. I was returning from France and Monte Carlo, where I'd given a talk about crypto anarchy, through U.S. Customs at San Francisco. Having just heard of Matt Blaze's experiences, I figured I'd be truthful and see what happened. (I can't recall the exact words, naturally, so this is just a rough version. Things were uncrowded at the Customs gate, and I was the only one in his line, in case it matters.) Young Customs Officer (YCO): "Where are you coming from?" Me: "Monte Carlo. And France." YCO: "Business or pleasure?" Me: "Business." YCO: "What was the business?" Me: "I met with cryptographers and bankers to discuss cryptography and political implications." YCO: " 'Cryptography'? " (A look of no comprehension.) Me: "Yes, cryptography. You know, secret codes, ciphers, stuff like that." YCO: "Were there any foreigners present?" Me: "Yes, it was in Monte Carlo. There were some Russians there, and lots of others." YCO: [brief pause] "Did you bring anything back with you?" Me: "No." YCO: [waved me through] In my carry-on luggage I had half a dozen magneto-optical disks, carring about a gigabyte of stuff. (As props to use during my talk on the France/Monte Carlo side, ironically, to show that borders are fully transparent.) By the way, there were no outgoing checks [unlike Matt, I didn't seek out permission to export anything], of course, and no checks at my entry point at De Gaulle Airport in Paris. [Though there were lots of cops with machine guns, and lots of dire warnings that bags left unattended might be destroyed, a precaution against bombs.] No checks into Monte Carlo, of course (I lived for a year near Monaco, so I knew this would be the case). Frequent travellers to Europe will no doubt confirm what I'm saying. I travelled to dozens of countries in Europe a while back, and never was checked at any borders, save for a quick glance at my passport. --Tim May We got computers, we're tapping phone lines, we know that that ain't allowed. ---------:---------:---------:---------:---------:---------:---------:---- Timothy C.

Impossible is an awfully strong word. If I was going to implement free digital stamps, I'd have a autoreply daemon (stamps(a)remailer.com) that when sent a mail, would respond with X number of valid stamps. If you're going to trust me not to log my remailer traffic, extending that trust to believing I won't log the stamp requests shouldn't be that much of a stretch. Alternatively, the stamp could consist of a unique-id, any unique-id, working identically to Usenet message ids. That way, the user can generate his own stamps without being forced to trust the remailer operator not to log them. I prefer the second option as it has both greater anonymity and allows for simple history file patching to the remailer. Either way, if the stamps/message-ids are forced to be inside the encrypted address block, mail-bombers can only get one message through. Even if the HNGs are instructed to add a stamp and re-encrypt the address block, when the spam-o-grams start getting routed through the pre-packaged route, they'll be stopped dead after one message gets through.

Re: COMMUNITY CONNEXION REFUSES TO CENSOR INTERNET SERVICES
by E. ALLEN SMITH 17 Dec '03

17 Dec '03

From: Rich Graves <llurch(a)networking.stanford.edu> >To play Devil's Advocate here, I don't think this is as big a deal as either side is making it out to be. At least according to dgillmor's column in today's San Jose Mercury News, SW meant (or has "clarified" his statements to mean) that he favors only limited remedial (not prior) restraints on "hate speech" (whatever the hell that means) on Web pages that approach "publishing" quality and distribution. SW does not favor and in fact opposes censoring newsgroups and email. ---------- Yes, it's good that he's favoring less restraint on speech than had previously appeared to be the case... but that still doesn't mean it's right. Is the censorship of broadcast media any better (of "indecent" speech) any better because after some time in the evening it doesn't apply? ---------- >I don't think any media outlet should be forced to carry something it finds objectionable. Libertarian notions like freedom of association and the fact that freedom of the press belongs to the guy who owns the damn press come into play here. ------------ What the SWC appears to be doing is not saying that they'd refuse certain groups access if they were running an ISP. They're trying to make it look like any ISP that carries certain web pages is evil... and, to some degree, this appears to me that they're putting pressure on governments to ban the speech in question. I would guess that they support the ban in Germany, for instance. In addition, the fewer ISPs are carrying the information, the easier it is to ban entirely. ----------- >I very much applaud Sameer for his principles and hard work, but SW and the like have their own principles. They're not incompatible in a free society. ----------- The problem is not the principles of the SWC... it's their tactics. -Allen

Viacrypt has versions of PGP complete with licenses for commercial use of the RSA and IDEA encryption algorithms. Viacrypt PGP comes in executable code only (no source code), but it is based on (and just as secure as) the freeware PGP. Viacrypt PGP for Windows is the only real Windows PGP (and even it is partially a quickwin executable that looks like a DOS port). Still, it is much better from an interface standpoint than all the others. Please contact ViaCrypt for pricing (about US $100 up), the latest platforms, and availablity at 800-536-2664 8:30am to 5:00pm MST, Monday - Friday. They accept VISA, MasterCard, AMEX and Discover credit cards. Viacrypt is currently working on preparing the release of version 4.0 (personal) and version 4.0 (business). The business edition adds a few extra key management features (like master keys) that are of use to businesses, but not really useful for persnal email.

PGP itself is morally neutral. What you do with it is not. Protecting privacy, prevention of criminal theft, and taking due diligence to protect certain business information (like credit card numbers, customer lists, etc.) are good uses for PGP. Concealing criminal or other immoral activity is wrong. You can fool the police some of the time, but you can't fool God. IS PGP LEGAL? Pretty Good Privacy is legal if you follow these rules: * Don't export PGP from the USA except to Canada, or from Canada except to the USA, without a license. * If you are in the USA, use either Viacrypt PGP (licensed for commercial use) or MIT PGP using RSAREF (limited to personal, noncommercial use). Outside of the USA, where RSA is not patented, you may prefer to use a version of PGP (2.6.i) that doesn't use RSAREF to avoid the restrictions of that license. * If you are in a country where the IDEA cipher patent holds in software (including the USA, Canada, and some countries in Europe), make sure you are licensed to use the IDEA cipher commercially before using PGP commercially. (No separate license is required to use the freeware PGP for personal, noncommercial use). For direct IDEA licensing, contact Ascom Systec. Ascom Systec has taken over the distribution of IDEA licenses effective April 1, 1995. Erhard Widmer is the person responsible for the sales aspects, and Peter Hartmann is responsible for the technical aspects. They can be reached as follows: Erhard Widmer, Ascom Systec AG, Dep't. CMVV Phone +41 64 56 59 83 Peter Hartmann, Ascom Systec AG, Dep't. CMN Phone +41 64 56 59 45 Fax: +41 64 56 59 90 e-mail: IDEA(a)ascom.ch Mail address: Gewerbepark, CH-5506 Maegenwil (Switzerland) * Don't sell PGP based on Philip Zimmermann's source code in North America unless you are reselling for Viacrypt (because they have an exclusive marketing agreement on Philip Zimmermann's copyrighted code). (Selling shareware/freeware disks or connect time is OK). This restriction does not apply to PGP 3.0, since it is a complete rewrite by Colin Plumb. Distribution and use restrictions on that version are still to be determined. * If you modify PGP (other than porting it to another platform or adapting it to another compiler), don't call it PGP (TM) or Pretty Good Privacy (TM) without Philip Zimmermann's permission. WHAT IS PHILIP ZIMMERMANN'S LEGAL STATUS? Philip Zimmermann was under investigation for alleged violation of export regulations, with a grand jury hearing evidence for about 28 months, ending 11 January 1996. The Federal Government chose not to comment on why it decided to not prosecute, nor is it likely to. The Commerce Secretary stated that he would seek relaxed export controls for cryptographic products, since studies show that U. S. industry is being harmed by current regulations. Philip endured some serious threats to his livelihood and freedom, as well as some very real legal expenses, for the sake of your right to electronic privacy. Although there was no direct and open legal battle, there was a lot of behind the scenes work by Phil's legal team, headed by Philip L. Dubois (dubois(a)dubois.com) GREAT JOB! If you ever are in the situation of needing a good lawyer to help you with similar Federal harassment, consider yourself fortunate if Mr. Dubois will take your case. Philip Zimmermann is breathing more easily these days, still a free man and able to work to support his family. The battle is won, but the war is not over. The regulations that caused him so much grief and which continue to dampen cryptographic development, harm U. S. industry, and do violence to the U. S. National Security by eroding the First Ammendment of the U. S. Constitution and encouraging migration of cryptographic industry outside of the U. S. A. are still on the books. If you are a U. S. Citizen, please write to your U. S. Senators, Congressional Representative, President, and Vice President pleading for a more sane and fair cryptographic policy.

PGP can do conventional encryption only of a file (-c) option, but you might want to investigate some of the other alternatives if you do this a lot. Alternatives include Quicrypt and Atbash2 for DOS, DLOCK2 for DOS & UNIX, Curve Encrypt (for the Mac), HPACK (many platforms), and a few others. Quicrypt is interesting in that it comes in two flavors: shareware exportable and registered secure. Atbash2 is interesting in that it generates ciphertext that can be read over the telephone or sent by Morse code. DLOCK is a no-frills strong encryption program with complete source code. Curve Encrypt has certain user-friendliness advantages. HPACK is an archiver (like ZIP or ARC), but with strong encryption.

Rather than manually encrypting and decrypting files, it is sometimes easier (and therefore more secure, because you are more likely to use it) to use a utility that encrypts or decrypts files on the fly as you use them in your favorite applications. This also allows you to automatically encrypt temporary files generated by your applications if they are on the encrypted volume. Secure File System (SFS) is a DOS device driver that encrypts an entire partition on the fly using SHA in feedback mode. Secure Drive also encrypts an entire DOS partition, using IDEA, which is patented. Secure Device is a DOS device driver that encrypts a virtual, file-hosted volume with IDEA. Cryptographic File System (CFS) is a Unix device driver that uses DES. http://www.cs.auckland.ac.nz/~pgut01/sfs.html ftp://ftp.informatik.uni-hamburg.de/pub/virus/crypt/disk/ ftp://ftp.csn.net/mpj/I_will_not_export/crypto_???????/disk/ ftp://ftp.csn.net/mpj/README for the ???????) ftp://miyako.dorm.duke.edu/mpj/crypto/disk/ ftp://ftp.nic.surfnet.nl/surfnet/net-security/encryption/disk/ ftp://ftp.demon.co.uk/pub/ibmpc/secdev/secdev14.arj WHERE IS PGP'S COMPETITION?

Eggs at Customs (fwd)
by Lindsay Haisley 17 Dec '03

17 Dec '03

There has (fortunately!) been a big crackdown recently on the illegal pet bird import trade, something akin to the slave trade of the 19th century for those of us who like pet birds. One of the methods people use to import birds is to wear special vests full of pockets for rare bird eggs.

We discussed this a bit at the Bay Area cpunks meeting yesterday. It'd be fun to know the politics involved and what we'll get out of this, but "easing export controls" could be anything from "dropping the limits on anything but designed-for-the-military crypto" to "64 bits with escrow". And, of course, "we'll release a policy statement in a few months" isn't highly informative either. On the other hand, it's an invitation for lobbying and public comment, so we might as well take advantage of it. #-- # Thanks; Bill # Bill Stewart, stewarts(a)ix.netcom.com, Pager/Voicemail 1-408-787-1281 # # "Eternal vigilance is the price of liberty" used to mean us watching # the government, not the other way around....
