RC4 compatibility testing

One data point: I can't say anything about the internals of RC4 versus the algorithm that Bill Sommerfeld is rightly calling 'Alleged RC4', since I don't know anything about RC4's internals. However, I do have a (legitimately acquired) copy of BSAFE2 and so I'm able to compare the output of this algorithm to the output of genuine RC4 as found in BSAFE. I chose a set of test vectors and ran them through both algorithms. The algorithms appear to give identical results, at least with these key/plaintext pairs. I note that this is the algorithm _without_ Hal Finney's proposed modification (see <199409130605.XAA24133(a)jobe.shell.portal.com>). The vectors I used (together with the ciphertext they produce) follow at the end of this message. -Ekr Disclaimer: This posting does not reflect the opinions of EIT. --------------------results

I would like to do the same in San Diego and then have a representative of the LA group meet the San Diego group representatives to sign some keys. It would be kind of nice to have a group of trusted cypherpunk members from each city to act as kind of the "CA" allowing you to eventually have some trusted keys from MIT and others that distribute software. I guess it would be a semi formal way to build a trusted hierarchy across the country. Next step would to have cypherpunk-sponsord pub-key-servers to hold these keys. I don't want it to sound too "clubish". I've just never personally met any of the cypherpunks and therefore have very few trusted keys since I can't trust any of the sigs.. Ya gotta start somewhere. I would be interested in seeing one in San Diego to key sign and discuss things like this, GAK, and others. What do you think? - -------------- P.S. Will be out on "special mission" from 1/16 until 10/10. When I return I would like to help make this happen.

Medusa on ftp.wimsey.bc.ca
by rarachel＠prism.poly.edu 17 Dec '03

17 Dec '03

Hey guys, I just sent medusa to ftp.wimsey.bc.ca, so you don't have to finger me if you can't or don't feel up to it. Right now it's in the uploads directory, but it will probably move later... Now for the software authors in all of us, a good question: WHAT ARE THE BEST FTP SITES TO SEND CRYPTO SOFTWARE TO? Is Soda being managed again for instance?

CIAC Notice - Virus with Crypto Tech...
by NetSurfer 17 Dec '03

17 Dec '03

Excerpted from CIAC, a report of a stealth virus that uses encryption as part of its attack. If the list thinks its of interest, I'll zap it over. But briefly: September 13, 1994 1600 PDT Number E-34 _____________________________________________________________________________ PROBLEM: A previously unknown computer virus is damaging systems. PLATFORM: All MS-DOS, PC-DOS, Windows systems, all versions. DAMAGE: Damages files, encrypts hard drive. SOLUTION: Update your Anti-Virus program to detect/remove the virus. _____________________________________________________________________________ VULNERABILITY While it is not epidemic, the virus has been seen at an East ASSESSMENT: coast site and it isn't detected by the current versions of most virus scanners (revised versions are upcoming.) The virus is intentionally damaging and all files on an infected machine are at risk. Warning: Removing the virus may make some files inaccessible (see below.) _____________________________________________________________________________ The virus is intentionally damaging. Every time an infected machine boots, the virus encrypts two cylinders of the DOS partition of the hard drive starting with the highest numbered cylinder and progressing to lower numbered ones. The virus then hides the fact that it is encrypting the hard drive by decrypting any of the encrypted sectors whenever they are accessed by the system. Only with the virus out of memory do you see the encrypted sectors. WARNING: Because of the encryption the virus does, be sure you copy any important files to a floppy disk or tape before removing the virus. The CHK_HALF program described below does not decrypt any encrypted cylinders, so when the virus is removed, the encryption key is lost with it and any files in the encrypted cylinders are lost. ===========================================================================

Someone (probably one of you!) has posted this item to several newsgroups. Note the forgery, a la port 25, of "David Sterndark"'s name. I, too, am shocked, simply shocked, and will be nofifying the "Casa Blanca" of this breach. -TCM Newsgroups: sci.crypt,alt.security,comp.security.misc,alt.privacy Path: netcom.com!sterndark From: sterndark(a)netcom.com (David Sterndark) Subject: RC4 Algorithm revealed.

However, I do have a (legitimately acquired) copy of BSAFE2 and so I'm able to compare the output of this algorithm to the output of genuine RC4 as found in BSAFE. I chose a set of test vectors and ran them through both algorithms. The algorithms appear to give identical results, at least with these key/plaintext pairs. I note that this is the algorithm _without_ Hal Finney's proposed modification (see <199409130605.XAA24133(a)jobe.shell.portal.com>). The vectors I used (together with the ciphertext they produce) follow at the end of this message. -Ekr Disclaimer: This posting does not reflect the opinions of EIT. --------------------results

Is cypherpunks archived somewhere?
by Phil Karn 17 Dec '03

17 Dec '03

Is the cypherpunks list being automatically archived where it can be retrieved by anonymous FTP? Yes, there *are* occasional nuggets on this list. Why, there's even the occasional practical item about cryptography buried in the massive rants to the libertarian choir. But I'd hate to miss stuff like the recent note on RC4. That's why I haven't unsubscribed yet. But something has to give. The list is just too high-volume, and the signal-to-noise ratio is now below -1.6 dB. It's just not worth it. It's a major reason why I always seem to run as much as a week behind on my mail. If there were an automatic FTP archive of the list, then I could unsubscribe while keeping the option of pulling over and grepping through an archived batch every so often just to see if anybody is actually doing anything.
