however, can still read both formats. Although this is annoying if you have a really old key that has lots of old signatures on it, the fact is that the older the key, the more likely someone has captured both it and the passphrase used to protect it. Therefore, I strongly recommend generating a new key and getting at least one other person to sign it. ARE MY OLD KEYS COMPATIBLE WITH MIT PGP 2.6? Unless they were created with the old, non-PKCS standard (i.e., created with PGP 2.2 or earlier, or created with PGP 2.3a with pkcs_compat set to 0), and unless they were created with a modulus of more than 1024 bits, then they are compatible. If a compatible key has an incompatible signature certificate, then the incompatible signature certificate will simply be stripped off by PGP 2.6. Otherwise, you can keep using your old key. In fact, if you just copy your key ring files to your new PGP 2.6 directory, then extract your old key with ASCII armor, it will be indistinguishable from a PGP 2.6 key, but have the same value, id, and signatures (assuming they were all in the PKCS format). WHY DOESN'T THE MIT KEY SERVER ACCEPT KEYS FROM PGP VERSIONS < 2.4? They don't want to be accused of contributing to the possibly infringing use of PGP 2.3a. WHY IS MY PGP 2.3a KEY ON THE MIT KEY SERVER? Because the MIT key server synchronizes with several non-USA key servers that run PGP 2.6ui or MIT PGP 2.6, and which accept keys from PGP 2.3a. When keys are extracted from those servers to synchronize with the MIT server, they appear to be coming from PGP 2.6, so they are accepted. WHY SHOULD I UPGRADE TO MIT PGP 2.6 FROM PGP 2.3a (BESIDES THE TIME BOMB)? First of all, if you are in the USA, the patent-legal status of MIT PGP 2.6 is good for your conscience. Second of all, there are a lot of bug fixes and features: Fixed a bug with the -z <passphrase> option. If no passphrase was given, PGP used to crash. When using -c, the IV is generated properly now, and the randseed.bin postwash is done. (This bug could have resulted in the same ciphertext being generated for the same plaintext, if the same passphrase is used.) Memory allocated with halloc() is now freed with hfree() in ztrees.c and zdeflate.c. (MS-DOS only.) The decompression code now detects end of input reliably, fixing a bug that used to have it produce infinite amounts of output on come corrputed input. Decompression has also been sped up. PGP -m won't try to write its final output to the current directory. This makes it less efficent if you want to save the text to a file, but more secure if you don't. If the line comment=<string> appears in the config file, the line "Comment: <string>" appears in ASCII armor output. Of course, you can also use this from the command line, e.g. to include a filename in the ASCII armor, do "pgp -eat +comment=filename filename recipient". PGP now enables clearsig by default. If you sign and ascii-armor a text file, and do not encrypt it, it is clearsigned unless you ask for this not to be done. The now enables textmode. Textmode detects non-text files and automatically turns itself off, so it's quite safe to leave on all the time. If you haven't got these defaults yourself, you might want to enable them. All prompts and progress messages are now printed to stderr, to make them easier to find and ensure they don't get confused with data on standard output such as pgp -m output. PGP now wipes temp files (and files wiped with pgp -w) with pseudo-random data in an attempt to force disk compressors to overwrite as much data as possible. On Unix, if the directory /usr/local/lib/pgp exists, it is searched fror help files, language translations, and the PGP documentation. On VMS, the equivalent is PGP$LIBRARY:. (This is PGP_SYSTEM_DIR, defined in fileio.h, if you need to change it for your site.) Also, it is searched for a default global config.txt. This file may be overridden by a local config.txt, and it may not set pubring, secring, randseed or myname (which should be strictly personal) The normal help files (pgp -h) are pgp.hlp or <language>.hlp, such as fr.hlp. Now, there is a separate help file for pgp -k, called pgpkey.hlp, or <language>key.hlp. No file is provided by default; PGP will use its one-page internal help by default, but you can create such a file at your site. On Unix systems, $PGPPATH defaults to $HOME/.pgp. PGP used to get confused if you had a keyring containing signatures from you, but not your public key. (PGP can't use the signatures in this case. Only signatures from keys in the keyring are counted.) PGP still can't use the signatures, but prints better warning messages. Also, adding a key on your secret key ring to your public keyring now asks if the key should be considered ultimately-trusted. Prviously, you had to run pgp -ke to force this check, which was non-obvious. On Unix, PGP now figures out the resolution of the system clock at run time for the purpose of computing the amount of entropy in keystroke timings. This means that on many Unix machines, less typing should be required to generate keys. (SunOS and Linux especially.) The small prime table used in generating keys has been enlarged, which should speed up key generation somewhat. There was a bug in PGP 2.3a (and, in fact in 2.4 and dating back to 1.0!) when generating primes 2 bits over a multiple of the unit size (16 bits on PC's, 32 bits on most larger computers), if the processor doesn't deal with expressions like "1<<32" by producing a result of 1. In practice, that corresponds to a key size of 64*x+4 bits. At the request of Windows programmers, the PSTR() macro used to translate string has been renamed to LANG(). The random-number code has been *thoroughly* cleaned up. So has the IDEA code and the MD5 code. The MD5 code was developed from scratch and is available for public use. Versions prior to 2.6 would not permit a new signature to be added to a key if there was an already existing signature from the same signer. Starting with version 2.6 newer signatures will override older ones *as long as the newer signature verifies*. This change is important because many keys have signatures on them that were created by PGP version 2.2 or earlier. These signatures can not be verified by PGP 2.5 or higher. Owners of keys with these obsolete signatures should attempt to gather new signatures and add them to their key. WHY SHOULD I UPGRADE TO MIT PGP 2.6 FROM PGP 2.6ui? If you are in the USA, PGP 2.6ui suffers from the same alledged patent infringement problems as PGP 2.3a. PGP 2.6ui also lacks most of the bug fixes and enhancements listed above since PGP 2.3a, since PGP 2.6ui is essentially just PGP 2.3a modified to accept both new and old packet version bytes (2 and 3). On the other hand, if you are outside of the USA and Canada, you should be careful not to offend the U. S. Department of State, Office of Defense Trade Controls, by exporting MIT PGP 2.6 from the USA or Canada. I suppose that you wouldn't break U. S. law if you got a copy of MIT PGP 2.6 that someone else exported, or you could get a copy of the PGP 2.6ui (that originated in Great Britain) if you don't care about the enhancements listed above, or if you want to be able to use 1264-bit keys. Note that if you use MIT PGP 2.6 in most countries, you are still bound by the RSAREF license because of the copyright law, and you are still limited in some countries to noncommercial use of PGP by the IDEA patent (unless you get a license from ETH Zurich). IS THERE AN EVIL PLOT, BACK DOOR, OR INTENTIONAL WEAKNESS IN MIT PGP 2.6? Not that I am aware of. It ships with source code, and I didn't see any way to hide such a thing in the source code that I looked at. Besides, if you really knew Phil Zimmermann, you would know just how repugnant such an idea is to him. IS THERE A LEGAL VERSION OF PGP FOR COMMERCIAL USE IN EUROPE? Not yet. To do that, you would have to (1) arrange to license the use of IDEA from ETH Zurich or wait for the coming triple-DES option in PGP, and (2) use the original (PGP 2.3a or 2.6ui) RSA code linked in with the new PGP (to avoid restrictions on the copyrighted RSAREF code). There is also the possibility of other local laws, such as those in France, restricting use of strong cryptography. IS THERE A LEGAL VERSION OF PGP FOR COMMERCIAL USE IN THE USA & CANADA? Yes. Use Viacrypt PGP for any commercial or personal use in the USA and Canada. I understand that there are some BSAFE-based PGP versions for commercial use in the USA, too, but you need to check with Philip Zimmermann on that to make sure that all of the copyright and licensing issues are handled properly. WHAT EXACTLY IS COMMERCIAL USE? I don't have an exact definition. Use some common sense. Are you encrypting sales reports, business plans, contract bidding information, and proprietary designs? Are your money making operations aided by the use of PGP? If so, and if one is available to you, you should buy the fully licensed commercial version. SINCE VIACRYPT PGP SHIPS WITH NO SOURCE, HOW DO I KNOW IT IS OK? Philip Zimmermann wrote or examined all of the source code. He says it is OK, so I trust him. I guess you have to decide for yourself. IS IT OK TO BUY VIACRYPT PGP, THEN USE MIT PGP FOR COMMERCIAL USE? RSADSI/PKP says it is not. On the other hand, since their only recourse is to sue you for damages, and since such a plan results in exactly the same revenue they would have if you did what they wanted, there are no damages to sue for. Personally, I use Viacrypt PGP except when beta testing PGP. IS THERE AN INTERCHANGE PROBLEM WITH THE DIFFERENT RSA ENGINES IN PGP? Fortunately, there is no problem interchanging RSA encrypted packets between original PGP, Viacrypt Digi-Sig, RSAREF, and BSAFE versions. They all do the same RSA computations. They are all different implementations of the same basic algorithm with a different legal status for each of them, which changes depending on what country you are in. The only annoyance is that unmodified copies of RSAREF and BSAFE can't handle more than 1024 bit RSA keys, but that isn't much of a problem (IMHO). HOW DO I UPGRADE FROM VIACRYPT PGP 2.4 TO VIACRYPT PGP 2.7 Call 800-536-2664 with your registration number, name, address, and credit card number handy. Hey, it is only US$10. No, I don't work for Viacrypt, nor do I get a commission on sales -- I just use Viacrypt PGP. WHERE DO I GET MIT PGP 2.6?

For a longer list, see the daily and montly postings on alt.security.pgp, or get ftp://ftp.csn.net/mpj/getpgp.asc WHAT KNOWN BUGS ARE IN MIT PGP 2.6? The function xorbytes doesn't. Replace the = with ^= to fix it. The effect of this bug is that RSA keys aren't quite as random as they should be -- probably not a practical problem, but worth fixing if you are going to compile the code yourself. DON'T SET PGPPASS when editing your keys, because if you do, and if you don't change your pass phrase, the key is lost. (If this happens, rename your backup keyring files to the primary files before you do anything else). These bugs have been fixed in the master source code, and will be corrected in the next release of MIT PGP. WHAT IS COMING IN FUTURE VERSIONS OF PGP? I won't steal the thunder from Philip Zimmermann, Jeff Schiller, Colin Plumb, and the rest of the team, but there is some neat stuff that they are working on. Transition from MIT PGP 2.6 and Viacrypt PGP 2.7 to the newer versions will be easier than transitions from other versions. If you have enhancements and suggestions for the PGP team, I suggest you coordinate with them so that your ideas can be integrated with the main PGP project. WHERE DO I REPORT BUGS IN PGP? Please send bug reports, bug fixes, ports to new platforms, and suggestions to pgp-bugs@mit.edu. WHERE DO I SEND OR FIND LANGUAGE KITS?

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.

(New Windows front end for PGP) To: cypherpunks@toad.com, ~rbarclay@TrentU.ca -----BEGIN PGP SIGNED MESSAGE----- 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 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.

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.

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!

There are three or four sets of remailers out there: - anon.penet.fi, which gives you an account an12345@anon.penet.fi which people can reply to. Send "Subject: help" to anon@anon.penet.fi and it'll probably give you a useful reply. Its big use is for anonymous Usenet posting with working replies. - The cypherpunks remailers, which are mostly one-way no-reply mailers; some also support Usenet posting. Soda is pretty typical. - Various enhanced cypherpunks remailers, which have features like encrypted reply addresses you can attach at the end. You can get information on using the soda remailer by sending email to remailer@csua.berkeley.edu, with "help" somewhere in the posting; I'm not sure if it wants it in the Subject: or in the body. That's the remailer that posts from "Tommy the Tourist" with random NSA-bait at the bottom of postings. Here's a recent posting on getting status of remailers. Note that some really only remail once per day, so they may be working fine even if it says they're not. ---- Date: Mon, 15 Aug 1994 13:39:33 -0700 From: Raph Levien <raph@kiwi.CS.Berkeley.EDU> To: cypherpunks@toad.com Subject: "finger remailer-list@kiwi.cs.berkeley.edu" now operational Hi all, I have written and installed a remailer pinging script which collects detailed information about remailer features and reliability. To use it, just finger remailer-list@kiwi.cs.berkeley.edu There is also a Web version of the same information, at http://http.cs.berkeley.edu/~raph/remailer-list.html Please do not take the uptime figures too seriously, at least for another week or so. The script has only been running reliably for a few days. Please let me know about any other remailers which I missed. I've only included remailers which can mail to arbitrary addresses, so I already know chop and twwells are missing. If you've got a Web page, please feel free to include a link to this page. If you think your Web page is relevant to the subject of remailers, let me know and I'll link it in. Comments and suggestions welcome!

Current problems in Crypt. 1. We need an Internet Chat PGP system for conversations in real time. Note: #Freedom channel on the Internet Chat system has carried out fast encrypted conversations for years. When a Cypherpunk contacted one of their members (Sargent someone), he was politely told that their system was private. Sargent was unwilling to disclose method. Is their system some kind of security by obscurity code that cannot be varied (like by a drop in crypt/decrypt algorithm)? Or maybe the crypt method could be a drop in variable method & Sarge was unaware of it? Possibly other #Freedom members would be more knowledgeable? Possibly, a knowledgeable & diplomatic Cypherpunk could hit paydirt by pursuing this. 2. Has Stealth PGP been done yet? 3. 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. 4. 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"? 5. If the above possibility happens & Cyperpunks' list is outlawed, does anyone have ideas how to make a "Fortress list"? PUSH EM BACK! PUSH EM BACK! WWWAAAYYYY BBBAAACCCK!
