That would make it harder to get the process started, since you would need 10 initialization vector blocks instead of 1, so it would bloat your messages more. How about this mode: c[i] = e(K1, e(k2, c[i-1]) ^ p[i-1]) ^ p[i] p[i] = e(K1, e(k2, c[i-1]) ^ p[i-1]) ^ p[i] The feedback possibilities are literally endless. The analysis of the effects on security, speed, error propagation, etc., are left as an exercise for the reader. <grin> Some standard modes have been well analyzed and accepted. They also are built into specialized cracking hardware. Offering and using multiple modes and multiple algorithms raises the cost of building specialized cracking hardware.

It may indeed serve that purpose, but the patch does serve as a sealant and when set up with the right lubricant it cleans the bore on the way out. This gave birth to the expression "one shot clean" - done right the bore is more or less always dirty from the last shot only as that shot cleaned the residue of the prior shot out by it lubricated patch. Civil war era muskets and later used a Minie ball, which was no ball at all but a tapered projectile which had no patching at all, just 5-700 grains (for a 58 cal musket, lighter for .45 and .50) of pure soft lead with a dab of lubricant in the hollowed base. >...

Quite right, but there's one more caveat you forgot here, Jim, when using the rod to tamp the ball down, its done with one hand with the rod held between two fingers. You sort of 'throw' the rod down onto the bullet, actually letting go, never holding the rod firmly and *never* putting your hand on top of the rod to push it down. (I saw one guy get a rod from a 58 cal three band Enfield shot through his hand at a musket shoot once and more than a few rods shot through rooves or into roof timbers in the shooting sheds or several hundred feet through the air on open ranges) Friction isn't the only source of stray ignition, powder embers from a prior shot when doing rapid fire shooting has been a common culprit. We had one musket shoot on a god awful hot sunny summer day and by the sixth and seventh rapid fire shots in the midday shooting the muskets were hot enough to cook off powder when combined with a little bit too forceful tamping, we had to curtail shooting til later in the day. All in all, the guys who had to use muzzle-loading weapons in war, personal defense, and hunting had to have been an adventuresome lot, todays weapons are boring in comparison. -----BEGIN PGP SIGNATURE----- Version: PGP for Personal Privacy 5.0 Charset: noconv iQEVAwUBNJ9kYz7r4fUXwraZAQGdWQf/QsP8OdDTpTvg2mIbe8v7/ovuPxLPJAwK BPYaOYTAYHKX3LqA+mxj5lx22K+7GufmrDsgL2WwS+sy/ZS/j2jdIKtr64QSXhg5 sIL66Oi1iyMgU/OJyLTCCAdbp5wTSfheznVzdNeee/N9xe0XNPCPoRhXpAYpyLh4 PZVkZ9BQSTV5mbuwLXy16c7yRCxoEaMrjR7GSQY6Y+/ycKnwq7oKWBbVAdg3pQVW 4a0vj6bT+HM8l1w6jvEALg4zSkz/vs2RvnJfYUvs4Xo6A4rqfTr96xfQyp6TH5oL 83V2yAa4EyTHoGpAVs7ANz7M7lnNo1QML9k8Z/oC1YznJdyFn4wFTw== =Tizl -----END PGP SIGNATURE----- Brian B.

Gilmore Publishes Strong Crypto Code Online for Authentication
by John Gilmore 17 Dec '03

17 Dec '03

[This announcement does not relate directly to the Bernstein case, but I felt the overlap of interest would be very strong. -- John] Strong Crypto Code Published Online for Authentication San Francisco, December 23, 1997 - Civil libertarian John Gilmore today published strong authentication source code on the Internet, making it available for worldwide access, despite U.S. National Security Agency attempts to restrict such software. He is publishing Domain Name System Security software that contains a complete copy of RSAREF, well-known cryptography software that is a predecessor to the DNSsafe software released in October by RSA Data Security, Inc. Mr Gilmore explains, "Internet publication of cryptography software is considered an export by the US Government, and often requires government permission under the Export Administration Regulations (EAR). But those regulations specifically exempt programs which merely prove that information is authentic (authentication), rather than hiding the information (privacy)." The export regulations were amended in 1989 to exclude authentication software. Since that time, however, the National Security Agency has been telling people privately that the exclusion only applies to ready-to-run "binary" programs. They have reportedly claimed that the regulations still require government permission to export the human-readable "source code" of authentication programs. The plain text of the regulations makes no such distinction, though; all authentication programs are exempt. Readers can obtain the software from Mr. Gilmore's web site for Domain Name System Security, at http://www.toad.com/~dnssec or at http://www.flash.net/~dnssec. Future releases will be available from the Internet Software Consortium, http://www.isc.org/bind.html. The Electronic Frontier Foundation, which Mr. Gilmore co-founded, is sponsoring a lawsuit to have the entire cryptography software export control regime overturned. In the three-year suit, Bernstein v. State, Judge Marilyn Hall Patel has invalidated export controls administered by both the State Department and the Commerce Department. She ruled they are an unconstitutional prior restraint against our First Amendment right to speak and publish about cryptography. The case is now in the Ninth Circuit Court of Appeals.

I've seen a couple and there are *lots* of references to the various manuals (and I think every wanna be professional soldier in the last 500 years has written one at some point) in the various readings I do studying tactical combat techniques but that doesn't make me an expert by any stretch of the imagination.

It was the first cicilian marketed semi-auto in the country ... the right hand safety can be operated and usually is by the thumb of the right hand its a big flat lever with a good sized tab on it, just extend the right thumb and push down. The magazine was a non removeable clip that could only be loaded from the top, no stripper clips. The one drawback to the weapon was it was a top eject and the it was said that the ejecting shell distracted the eye of the shooter, personally I got used to that within the first 100 round I fired with it. >Is this a military grade weapon or sport? > >> >A parallel pistol example would be nice too, if you're so inclined. >> >> I don't know of any pistols .... except that in the case of the >> ubiquitous military .45 (1911A1) while one can easily insert a magazine >> with the gun on safe, it isn't truly loaded til a round is chambered >> which involves coming out of safe to rack the slide > >Interesting since the 1911 I use doesn't exhibit this ...

I don't know whether I should feel blessed or cursed now....I spent several hours today clearing the yard (covered in grass) of tree limbs that were knocked down from the storm last week and in preperation for the storm to come in to town tomorrow...still have to mow that green stuff since it's getting a tad tall...maybe this weekend. Personaly, I can't imagine why anyone would allow them to build a city without parks and grass and trees and such. Hell, we have laws in Austin that make such things mandatory...there is currently a big fight going on about 'Triangle Park' here in Austin between leaving the 50+ acres at N. Lamar, Guadalupe, & 45th alone or selling to make a movie theatre and parking lot. Looks like the trees are gonna win this one...I know my dog certainly likes romping in the mud puddles...(I live about 10 blocks away) So big bucks don't always win and the city & state (the park is owned by the state hospital and currently houses some sort of juvenile center in one small corner) governments do sometimes listen to the people of a neighborhood over commercial interests. Money is not more important than trees sometimes & government sometimes does listen...
