-----BEGIN PGP SIGNED MESSAGE----- WHERE TO GET THE PRETTY GOOD PRIVACY PROGRAM (PGP) FAQ Revised 24 May 1996 Disclaimer -- I haven't recently verified all of the information in this file, and much of it is probably out of date. For questions not covered here, please read the documentation that comes with PGP, get one of the books mentioned below, or search for other relevant FAQ documents at rtfm.mit.edu and on the alt.security.pgp news group. A NOTE FROM THE FAQ MAINTAINERS Peter Herngaard <pethern@datashopper.dk> is taking over the maintenance of this FAQ until further notice. Some of you sent me (Mike Johnson) corrections and suggestions for this FAQ, and I stored them away on my hard disk to edit from. Then, Windows 95 got indigestion (induced by a sound card) and destroyed all of the data in that partition. If you suggested changes and they aren't in this FAQ, please send them to Peter Herngaard <pethern@datashopper.dk>. WHAT IS THE LATEST VERSION OF PGP? Viacrypt PGP (commercial version): 2.7.1 (4.0 is due out Real Soon Now) MIT & Philip Zimmermann (freeware, USA-legal): 2.6.2 Staale Schumacher's International variant: 2.6.3i for non-USA (2.6.3ai source code only); 2.6.3 for USA WHERE CAN I GET VIACRYPT PGP? Just call 800-536-2664 and have your credit card handy. WHERE IS PGP ON THE WORLD WIDE WEB? U.S. only availability: PGP: http://web.mit.edu/network/pgp-form.html PGPfone: http://web.mit.edu/network/pgpfone International availability: PGP and PGPfone: http://www.ifi.uio.no/pgp/ WHERE CAN I FTP PGP IN NORTH AMERICA? If you are in the USA or Canada, you can get PGP by following the instructions in any of: ftp://net-dist.mit.edu/pub/PGP/README ftp://ftp.csn.net/mpj/README.MPJ ftp://miyako.dorm.duke.edu/pub/GETTING_ACCESS ftp://ftp.csua.berkeley.edu/pub/cypherpunks/pgp/ ftp://ftp.gibbon.com/pub/pgp/README.PGP ftp://ftp.wimsey.bc.ca/pub/crypto/software/README WHERE IS PGP ON COMPUSERVE? GO NCSAFORUM. Follow the instructions there to gain access to Library 12: Export Controlled. AOL Go to the AOL software library and search "PGP" or ftp from ftp://ftp.csua.berkeley.edu/pub/cypherpunks/pgp or another site listed above. It is possible to get PGP from ftp sites with hidden directories with the following trick: (1) View the README file with the hidden directory name in it, then quickly (2) Start a new ftp connection, specifiying the hidden directory name with the ftp site's address, like ftp.csn.net/mpj/I_will_not_export/crypto_xxxxxxx (where the xxxxxxx is replaced with the current character string).

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 (2.6.3i) 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: 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@ascom.ch Mail address: Gewerbepark, CH-5506 Maegenwil (Switzerland) Viacrypt has an exclusive marketing agreement for commercial distribution of 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. If you modify PGP (other than porting it to another platform, fixing a bug, or adapting it to another compiler), don't call it PGP (TM) or Pretty Good Privacy (TM) without Philip Zimmermann's permission. IMPORTANT: Please note that there is an official distribution site for MIT PGP and another for the International version: WorldWideWeb references: U.S/Canada non-commercial use: http://web.mit.edu/network/pgp-form.html Norway/International non-commercial use: http://www.ifi.uio.no/pgp/ U.S. commercial use: http://www.viacrypt.com 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. 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, DLOCK 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. A couple of starting points for your search are: U.S. only availability: ftp://ftp.csn.net/mpj/qcrypt11.zip ftp://ftp.csn.net/mpj/README ftp://ftp.miyako.dorm.duke.edu/pub/GETTING_ACCESS International availability: ftp://ftp.informatik.uni-hamburg.de/pub/virus/crypt/file/ ftp://ftp.dsi.unimi.it/pub/crypt/code/ HOW DO I SECURELY DELETE FILES (DOS)? If you have the Norton Utilities, Norton WipeInfo is pretty good. I use DELETE.EXE in del110.zip, which is really good at deleting existing files, but doesn't wipe "unused" space.

The nature of Windows is that it can swap any memory to disk at any time, meaning that all kinds of interesting things could end up in your swap file. ftp://ftp.firstnet.net/pub/windows/winpgp/wswipe.zip WHERE DO I GET PGPfone(tm)? PGPfone is in beta test for Macintosh and Windows'9 users. The MIT has shut down their ftp distribution of PGPfone <tm> for Macintosh and Windows'95, so within the U.S/Canada you must obtain PGPfone <tm> using a WorldWideWeb browser.

Bill Dorsey, Pat Mullarky, and Paul Rubin have come out with a program called Nautilus that enables you to engage in secure voice conversations between people with multimedia PCs and modems capable of at least 7200 bps (but 14.4 kbps is better). See: U.S. only availability: ftp://ripem.msu.edu/pub/crypt/GETTING_ACCESS ftp://ripem.msu.edu/pub/crypt/other/nautilus-phone-0.9.2-source.tar.gz ftp://ftp.csn.net/mpj/README ftp://miyako.dorm.duke.edu/pub/GETTING_ACCESS International availability: ftp://ftp.ox.ac.uk/pub/crypto/misc ftp://utopia.hacktic.nl/pub/replay/pub/voice/ The official Nautilus homepage is at: http://www.lila.com/nautilus/ HOW DO I ENCRYPT MY DISK ON-THE-FLY? 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. CryptDisk is a ShareWare package for Macintosh that uses strong IDEA encryption like PGP.

RIPEM is the second most popular freeware email encryption package. I like PGP better for lots of reasons, but if for some reason you want to check or generate a PEM signature, RIPEM is available at ripem.msu.edu. There is also an exportable RIPEM/SIG.

Send mail to one of these addresses with the single word "help" in the subject line to find out how to use them. These servers sychronize keys with each other. There are other key servers, too. pgp-public-keys@keys.pgp.net pgp-public-keys@keys.de.pgp.net pgp-public-keys@keys.no.pgp.net pgp-public-keys@keys.uk.pgp.net pgp-public-keys@keys.us.pgp.net WWW interface to the key servers: http://www.pgp.net/pgp/www-key.html http://www-swiss.ai.mit.edu/~bal/pks-toplev.html For US $20/year or so, you can have your key officially certified and published in a "clean" key database that is much less susceptible to denial-of-service attacks than the other key servers. Send mail to info-pgp@Four11.com for information, or look at http://www.Four11.com/ Of course, you can always send your key directly to the parties you wish to correspond with by whatever means you wish.
