PGP general. PGP is Pretty Good Privacy from Phil Zimmermann. It is currently the best available encryption available to civilians at large. Zimmermann is the programmer on the original PGP versions but now, apparently, just guides other programmers in making improved versions. PGP uses two encryption algorithms: RSA for its Public Key powers & IDEA for its bulk encryption. The advantages of PGP over other crypt/decrypt systems are: 1. RSA algorithm. Allows users to communicate without needing a secure channel to exchange keys. - PUBLIC KEY ENCRYPTION. 2. The program system has been very well done & has huge development support. 3. It has huge popularity. 4. Security is guaranteed with distribution of source code & public investigation. 5. Its free. 6. Both RSA & IDEA are "STRONG" algorithms. Section 2: Michael Johnson's PGP FAQ contribution Michael Paul Johnson <mpj@netcom.com> has an excellent faq on Subject: Where to Get the Latest PGP (Pretty Good Privacy) FAQ /* (Last modified: 31 October 1994 by Mike Johnson) */ You can get this faq by anonymous ftp to: ftp.csn.net /mpj/getpgp.asc It is also posted monthly on alt.security.pgp The latest versions of PGP are VIACRYPT PGP 2.7 , MIT PGP 2.6.2 & PGP 2.6ui & the new PGP 2.6.i . Which is best? I would say MIT PGP 2.6.2 although PGP 2.6.i is a close contender. MIT's has source code, Phil Zimmerman's blessing & is US legal. For a further discussion of variations, consult Michael Johnson's FAQ. Section 3: Michael Johnson's PGP bomb contribution. From: Michael Johnson <mpj@csn.org> Subject: PGP Time Bomb FAQ PGP TIME BOMB FAQ Michael Johnson writes: "There has been some confusion about the annoying "Time Bomb" in MIT PGP2.6, as well as some other PGP version compatibility issues.

Stealth PGP 37 Stealth PGP refers to a PGP file that does not have the RSA prefix tag on the beginning of a PGP encrypted file or to PGP utility software that disguises this tag. Possibly, a later version of PGP with have this as an option. The advantages of "Stealthy" PGP are that its files cannot be found by Internet search programs that hunt for the PGP/RSA tag & that a "Stealthy" file may be more securely hidden by a good steganography program. From: Mark Grant <mark@unicorn.com> Subject: Stealth PGP Responding to my question "Has Stealth PGP been done yet?" Mark Grant says: Kind of, there's a 'stealth' filter available that strips and attaches headers to PGP messages after encryption. It's available from various places, and the documentation is available on my 'other people's PGP addons' WWW page : http://www.c2.org/~mark/pgp/other.html There's also information about Privtool, my PGP-aware mail program for Sun workstations at : http://www.c2.org/~mark/privtool/privtool.html Mark EMAIL: mark@unicorn.com URL : http://www.c2.org/~mark/ Chapter 2.

The text is, of course, encrypted text rather than plain text. The current best steganography program has been done by Arsen Arachelian Below, follows his text contribution: From: rarachel@prism.poly.edu (Arsen Ray Arachelian) WNSTORM is available from: ftp.wimsey.bc.ca:/pub/crypto/software/dist/US_or_Canada_only_XXXXXXX/Steg Usual routine to get it. i.e. cd /pub/crypto/software, get the README file, and if you agree to the terms then follow the instructions. Short description off the top of my head (I wrote the beastie) Another info scrap should be in the same directory as WNSTORM. WNSTORM is a data encryption/steganography utility which is pretty secure for most uses. Unlike some stego systems WNSTORM is expandible, all you have to do is write your own LSB injector/extractor for whatever data format you wish to hide information into. WNSTORM doesn't require the recipient of the host picture, sound, movie, etc. to have the original un-stormed picture. Unlike primitive stego programs, WNSTORM doesn't compare an stormed picture with an unstormed picture. WNSTORM will cover its tracks statistically. If it changes a 0 bit in the LSB data stream to a zero, or a 1 bit to a 1, it does nothing. If it changes a 1 bit to a zero, it will balance itself by changing an unused adjacent 0 bit to a 1. Ditto for a 0->1 transform. WNSTORM will NOT change every bit of the LSB in order to prevent detection. It will use a passkey along with a probabilistic algorithm to decide which bits it will change. The algorithm for picking bits depends on the previous succesfully encoded/decoded cyphertext AND the passkey. Internally WNSTORM works by picking "windows" or "packets" of bytes out of either a random number stream or an LSB stream extracted from a picture, sound, movie, etc. It then injects eight bits of cyphertext into this window. Each window is of variable size. The bit locations where the bits are inserted are randomly exchanged for each pass. The bit values are also randomly exchanged for each pass. WNSTORM includes an injector/extractor for PCX images, however I will write more injecotr/extractor programs for it in the future, and OTHERS can do so as well. Chapter 3. Shells for PGP. Section 1. Christopher W. Geib's WinPGP26.ZIP From: "David K. Merriman" <merriman@metronet.com> Subject: Christopher W. Geib's Windows PGP shell I've just finished making an ftp deposit to soda in the cypherpunks/ incoming directory of WinPGP26.ZIP; it's the latest version of the Windows PGP shell Shareware, and understands 2.6/2.6ui/2.7. Dave Merriman Section 2. Ross Barclay's WinFront 3.0 From: Ross Barclay <RBARCLAY@TrentU.ca> Subject: PGP WinFront 3.0 Now Available! (New Windows front end for PGP) To: cypherpunks@toad.com, ~rbarclay@TrentU.ca -----BEGIN PGP SIGNED MESSAGE----- /* signature wrecked due to included text from another contributor. Gary Jeffers */ Announcing PGP WinFront 3.0 ~~~~~~~~~~~~~~~~~~~~~~~~~~~ A freeware Windows front end for PGP 2.3a and 2.6 Copyright 1994 Ross Barclay (rbarclay@trentu.ca) WHAT IT IS: - PGP WinFront is the most fully featured free (or otherwise) Windows front end available. It will make using PGP easy for beginners, and it will drastically increase the speed at which experts use it too. PGP WinFront is now into is third revision and I have tried to implement as many of the suggestions that I received as possible. PGP WinFront was designed by its users, but was coded by me. Features: - Supports secret key ring placement on floppy drive - Support en/decryption to/from clipboard - Move / Copy / Delete files - Online hypertext help - Online hypertext PGP help - Keyring reader to pick names, view key characteristics - Keyring reader supports less-often used "huge" keyrings - Signature Checker - Very configurable - over 25 user-definable settings - more . . . This program does too much to list here. And it's free! This version is a complete rewrite of the popular PGP WinFront 2.0. The feature-set has largely been set by users who sent in suggestions. Please read the file README.TXT and peruse the help files. Please send me your comments. HOW TO GET IT: At the moment, there are 2 ways to get this program: 1) Via FTP - The PGP WinFront 3.0 filename is called PWF30.ZIP. - It has been uploaded to the incoming directories of the following FTP sites: ftp.cica.indiana.edu ftp.eff.org ftp.wimsey.bc.ca /* from Gary Jeffers. There has been a problem getting pwf30 from these sites. However, it CAN ACTUALLY be ftp'ed with the following info.: ftp.wimsey.bc.ca: /pub/crypto/software/dist/US_or_Canada_only_XXXXXXXX/PGP/Misc/pwf30.zip */ -- Mark Henderson -- markh@wimsey.bc.ca, henderso@netcom.com (personal accounts) RIPEM 1.1 MD5OfPublicKey: F1F5F0C3984CBEAF3889ADAFA2437433 ViaCrypt PGP Key Fingerprint: 21 F6 AF 2B 6A 8A 0B E1 A1 2A 2A 06 4A D5 92 46 cryptography archive maintainer -- anon ftp to ftp.wimsey.bc.ca:/pub/crypto */ black.ox.ac.uk soda.berkeley.edu ftp.informatik.uni-hamburg.de ftp.ee.und.ac.za ftp.demon.co.uk - Hopefully, they will be slotted into the PGP directories soon. On CICA, it will be placed into \pub\pc\win3\utils. That is where PWF20.ZIP was placed. - Once you get the program, please upload it to other FTP sites! 2) From Colorado Catacombs BBS - dial (303)772-1062. The file is called PWF30.ZIP - once you get the program, please upload it to other BBSs. *** The mail access system I had was discontinued. This is because the file was too big to fit into my account. However, you can still register PWF and request certain PGP and PWF related items using my mail access system. Details of these are on the "About" screen of PWF 30. - --Ross Barclay - ------------------------------------------------------------------------- Ross Barclay (rbarclay@trentu.ca), Assistant Editor | To receive my PGP | public key, send PC NEWS Review: Windows Edition | me e-mail with the Bellevue, WA (206) 399-8700 | subject: GET KEY - ------------------------------------------------------------------------- To receive PC NEWS Review, send me e-mail with the subject: GET PNR. - ------------------------------------------------------------------------- -----BEGIN PGP SIGNATURE----- Version: 2.6 iQBVAwUBLmZ7fdgpRteEZ9JhAQFeXgIAxIpvJQeMsx7YecNgtusBDMqL662XFeX2 qL0qF8HcN4ReZ9MYjtn9t8N1zWGxkPOXQEI3KfM7uk8JTzxjZ5LG2g== =gSYT -----END PGP SIGNATURE----- /* Section 3.

Section 2. Viruses sources. AMERICAN EAGLE PUBLICATIONS Cypherpunks, I have found a source of info. that I just must share! American Eagle Publications, Inc. P. O. Box 41401 Tucson, AZ 85717 I'm sure they will send you a catalog just for the asking. So, what are they about? They are about VIRUSES! They don't just carry a couple of virus things - they are the VIRUSES-ARE-US of the virus world! They have a journal: Computer Virus Developments Quarterly. They have books on viruses, virus protection, cryptanalysis, the science fiction book "Heiland", a CD-ROM for $99.95 of several thousand live viruses, disks of viruses with source code, executable & utilities, programs & cards for boot protection, & even a virus IDEA computer system protector. Copy follows for two items of particular interest to Cypherpunks: POTASSIUM HYDROXIDE, KOH By the "King of Hearts" A sophisticated piece of software which uses ideas first developed by computer virus writers to secure your computer system against those who would like to get their hands on the information in it. You give KOH a pass phrase, & it uses state of the art IDEA data encryption algorithm to encrypt all of the information on your hard disk & your floppies. It is, for all intents & purposes, unbreakable, & works well with DOS & Windows. Many encryption programs offered commercially are easily cracked, but this one is not. Some people call this program a virus, come say it is not. In ways, it acts like a virus to do some of your security housekeeping for you. Yet at worst it is a friendly virus that lets you choose when & how it will replicate. program & manual on disk, $10 program, full source, & manual on disk, $20 (Overseas customers add $12: KOH cannot be exported from the US, but since it was not developed in the US, we will forward your order to the overseas distributor. Please allow 6 weeks for delivery) HEILAND By Franklin Sanders 276 pages, Paperback, 1986 Here's an entertaining book about America in the year 2020. If you wonder if it's proper to use viruses in wartime or if such a virus could be termed "good", this book will give you some food for thought. Sanders makes use of computer "worms" when the oppressed people of the US attack the federal government in an all-out war against tyranny. Sanders uses his worms right too - not as some all-powerful monster. Rather, they are deployed as part of a larger military strategy. For a book written in 1986, that's not bad! And if you're fed up with the government, this book is sure to give you a vision for the future. Sanders has been part of the mounting tax protest in this country. He's fought the IRS in court for years & won some important battles. Unfortunately the government seems to be con- firming some of his worst suspensions about them. Now you can get a good dose of his philosophy & his ideas about remedying our problems. And if you work for the government, don't be offended - this book is doubly recommended for you! Book, $8.00 for shipping add $2 per book. 5% sales tax for AZ. residents. It is my belief that in the next few years more uses for viruses than just being a vandal will be found. Also, they may find a place in protecting our electronic freedom. - for instance virus remailers. Also see my previous post - The FREEDOM DEAMON. Also, they have a place in my CHATTERBOX concept(a remailer for chat mode or commands). "Viruses aren't just for Sociopaths anymore!" Also, I suspect the state may start cracking down on virus tech- nology. Incidentally, did you all know that crypt has a place in modern viruses? Encryption is used to hide "nasty" code & virus signatures until they get into the system & decrypt. Yours Truly, Gary Jeffers PUSH EM BACK! PUSH EM BACK! WWWAAAYYY BBBAAACCCKK!
