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 has an excellent faq on Subject: Where to Get the Latest PGP (Pretty Good Privacy) FAQ (Last modified: ??????????????? 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 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. This is an attempt to clear up some of that confusion." You can get this faq by anonymous ftp to: ftp.csn.net /mpj/pgpbomb.asc Section 4. PGP2.6.2 from Sameer. From: sameer Subject: PGP 2.6.2 on ftp.csua.berkeley.edu Date: Thu, 27 Oct 1994 03:19:19 -0700 (PDT) PGP 2.6.2 is now available on ftp.csua.berkeley.edu in /pub/cypherpunks/pgp/pgp262 Not for export outside of the United States in violation of ITAR restrictions. -- sameer Voice: 510-841-2014 Network Administrator Pager: 510-321-1014 Community ConneXion: The NEXUS-Berkeley Dialin: 510-549-1383 http://www.c2.org (or login as "guest") sameer@c2.org Section 3. 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 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" 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 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.

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!

For DOS/WINDOWS users. Hello Gary -- > Besides demon.co.uk & Penet, are there any remailers that a DOS machine user > can use? & how would I use the remailers? Thank You, Gary Jeffers Any of the type I remailers (non-mixmaster, that is) can be used from a DOS box if you can get the mail off it to the first remailer somehow. Hand remailer nesting is a pain, so batch files are in order. You might try this -- it's based on the Karl Barrus scripts, modified to do only remailer chaining (no reply blocks) and to id keys by number rather than remailer name so as to reduce opportunity for ambiguity. You'll need to increase the DOS environment space to use a lot of remailers. The message will be threaded through the remailers listed by number in right-to-left order, and you send the initial message to the "last", ie. rightmost, remailer in the list you give. The syntax is: lm [next number] [etc.] Test the remailers with single bounces to yourself: it's been a while since I purged non-responders from this collection. regards, -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Dept. of Biology Jennifer Mansfield-Jones University of Michigan cardtris@umich.edu http://www.umich.edu/~cardtris/cardtris.htm <--- PGP key available This batch file prepares a file for transmission to the last file in the parameter list. It pgp encrypts it as well as adding other info.. lm is name of the batch file (lm.bat). Target address is where you want to send it. 1st you run the batch file with the parameters. This will prepare your file for sending. At end of execution, the batch file will give you the remailer address to send to & repeat the name of the file to send.

Current problems in Crypt. 1. Has Arsen Arachelian really solved the problem of discovery of crypt in steganograpy by statistical examination of the least significant bits in his WNSTROM? I have seen no debate on this. 2. If the Feds capture the internet & put their anti-privacy hardware & protocols in place & outlaw remailers, does anyone have any idea how to build secure & effective remailers? A "Fortress remailer"? 3. If the above possibility happens & Cyperpunks' list is outlawed, does anyone have ideas how to make a "Fortress list"? Currently, we have Fortress Cryptography & State Sufferance remailers, mailing lists & newsgroups. We must have Fortress: remailers, mailing lists & newsgroups! Chapter 8. Text sources. Section 1. Books. Part 1. Simson Garfinkel's PGP book. From: Stanton McCandlish Subject: O'Reilly PGP book Date: Wed, 7 Sep 1994 13:38:58 -0400 (EDT) coming soon, PGP hits the mainstream: PGP: Pretty Good Privacy by Simson Garfinkel 1st Edition November 1994 (est.) 250 pages (est),ISBN: 1-56592-098-8, $17.95 (est) PGP is a freely available encryption program that protects the privacy of files and electronic mail. It uses powerful public key cryptography and works on virtually every platform. PGP: Pretty Good Privacy by Simson Garfinkel is both a readable technical users guide and a fascinating behind-the-scenes look at cryptography and privacy. Part I of the book describes how to use PGP: protecting files and email, creating and using keys, signing messages, certifying and distributing keys, and using key servers. Part II provides background on cryptography, battles against public key patents and U.S. government export restrictions, and other aspects of the ongoing public debates about privacy and free speech. -- Stanton McCandlish

PGP was electronically published as free software in 1991. Little did I realize what this project would lead to. PGP has become the worldwide de facto standard for e-mail encryption. I've admired Bill Stallings's writings in computer science for some years before PGP, and here he is writing a book about my program. How can I talk about how great his book is, without, by implication, talking about how great PGP is? It's hard to write a foreword for his book about PGP without sliding into some measure of self-indulgence. I've been so close to this project for so long that I sometimes lose sight of the scope of what PGP provides. I got the manuscript for Bill's book in the mail the other day -- the book you are holding. Sitting down with it, flipping through it, endless pages of diagrams, the formal treatment of it, services provided by PGP. It wasn't till I saw his book on PGP that I could step back and see PGP as others see it. The breadth of it. As a software engineer, I'm used to either documenting my own software, or having a random company tech writer document it. All software engineers get that. But having William Stallings do the manual for your software -- it's sort of like having your portrait done by a world-class artist. There are a very small number of software packages that have far- reaching political implications. Most software that fits in such an influential category has negative effects on our civil liberties. For example, government intelligence agencies use a software package called PROMIS, which is a powerful tool of governments to track people's activities, movements, spending, political affiliations, et cetera. Now that is a piece of software with far-reaching political implications. Mostly bad ones. Then there is the software that the Medical Information Bureau uses to classify people who file medical insurance claims, to put them on a medical "black list", so that they cannot purchase any medical insurance ever again. That software has far-reaching political implications -- enough to raise a large- scale backlash in our society to do something about it. In most cases, it seems that software that has powerful political effects is software designed to strengthen the strong and weaken the weak. But PGP also has far-reaching political implications. Mostly good ones. In the Information Age, cryptography affects the power relationship between government and its people. The Government knows this all too well, as evidenced by their recent policy initiatives for the Clipper chip, which would give the Government a back door into all our private communications -- an Orwellian "wiretap chip" built into all our telephones, fax machines and computer networks. PGP strikes a blow against such dark trends, and has become a crystal nucleus for the growth of the Crypto Revolution, a new political movement for privacy and civil liberties in the Information Age. This government has done all they can to stop the emergence of a worldwide encryption standard that they don't have a back door into. And that same government has placed me under criminal investigation for unleashing this free software on the world. If indicted and convicted, I would face 41 to 51 months in a federal prison. Despite the pressure the Government has brought to bear against PGP (or perhaps because of it), PGP has become the most widely used software in the world for e-mail encryption, used by a variety of activists, and anyone else needing protection from the powerful. It's also used by ordinary people to protect their personal and business communications from prying eyes. PGP may have a future as an official Internet standard, as the Internet Engineering Task Force develops an interest in it. No one who wants to work in the area of Internet e-mail privacy should neglect studying PGP. Because of the "fax machine effect", more people who want to encrypt their e-mail are getting PGP because everyone else who encrypts their e-mail is already using it. Naturally, I want people to read the Official PGP User's Guide, which comes with the electronic distribution package of PGP (also in book form from MIT Press), because I wrote it. Also, I'm more entertaining and personable in my book. And more political. But Bill Stallings' book is more comprehensive than mine, more thorough, covering more detail, with a lot more diagrams. He's really good at completely nailing it down in a book. In fact, I'll probably use his book myself as my preferred reference to PGP.

Do we really have this capability now? According to following post we do! This info has not been verified yet. You may want to experiment for yourself. Section 1. prig(cryptical)'s offering. From: prig0011@gold.tc.umn.edu Subject: IRC Encryption There was a thread a while back about encrypted conversations on channel #freedom on irc. I came across the software I believe they are using. Its a package called Circ, and it is available from archives of comp.sources.misc volume 38 issue 10. It is interesting in that it uses RSA for key exchange, and triple DES for the encryption. The Circ package includes an earlier implementation "socks" which is a stand alone encrypted irc client. I think this is what they use on #freedom. This is an interesting tool for a couple of reasons. irc can be as anonymous as you want to make it. There are ways of hiding what site you're coming from, your real username, you can change your nick often as you want, and it's got a high enough usage that you can lose yourself in a crowd. It supports background file transfers. You can create a channel and lock it to uninvited people. It is supported pretty much net-wide, if you can telnet, you can irc. Interesting stuff, and I'll be playing more with it in the near future. BTW: my nick is cryptical on irc. :) Section 2. Ed Carp's offer. According to Ed Carp, the package has been around for a long time & he's had it on his system for monthes. Ed says: "If anyone wants it, they can email me and I'll send it to them, tarred, gripped, and uuencoded." Ed Carp is ecarp@netcom.com PUSH EM BACK! PUSH EM BACK! WWWAAAYYYY BBBAAACCCK!
