i should note that the tools under gnu.crypto.tools do generate the test vectors (at least for the gnu.crypto.cipher package) in NESSIE and (almost) NIST forms. yet the verification of the result is not straightforward: * either the gnu.crypto.tool tools generate a more or less exact match of the published test vectors and then a diff tool is run over these two files to detect eventual differences, or * we write a new tool that would read a published test vector file and try to generated the same from the implementation and compare the results --something that would automate the process of verifying an implementation basically. 6. deliverables: what should our deliverables consist of? separate archives for source, binaries, documentation? combine the lot? should we include the designers' reference documentation? their test vectors? have a look at the sizes of these files before giving an answer please. 7. versioning: what type of versioning should we use? things to do later: this is still an open issue, and i would leave that for everybody to suggest what they can do relative to the time they can spend working on this project. cheers; rsn From HBG42@hotmail.com Tue Nov 27 20:54:20 2001 Received: from delysid.gnu.org ([158.121.106.20]) by fencepost.gnu.org with esmtp (Exim 3.22 #1 (Debian)) id 168tvY-00067Y-00 for ; Tue, 27 Nov 2001 20:54:20 -0500 Received: from [144.137.145.148] (helo=hotmail.com) by delysid.gnu.org with smtp (Exim 3.20 #1) id 168tv0-0001l8-00 for ; Tue, 27 Nov 2001 20:53:55 -0500 MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="=200111272028=" To: classpathx-crypto@gnu.org From: HBG42@hotmail.com X-Mailer: 48F7820E.4886299B.a077b1eee344268d1452a934c9dd02e7 Organization: Home Business Group Message-Id: Date: Tue, 27 Nov 2001 20:53:55 -0500 Subject: [Classpathx-crypto] Did You Get Your Check?

AS SEEN ON NATIONAL TV: Are you making over half million dollars every 4 to 5 months from your home? A one time investment of only $25 U.S. Dollars get's you on the road to financial success. ALL THANKS TO THE COMPUTER AGE AND THE INTERNET ! =========================================== BE A MILLIONAIRE LIKE OTHERS WITHIN A YEAR!!! Before you say ''Bull'', please read the following. This is the letter you have been hearing about on the news lately. Due to the popularity of this letter on the Internet, a national weekly news program recently devoted an entire show to the investigation of this program described below, to see if it really can make people money. The show also investigated whether or not the program was legal. Their findings proved once and for all that there are ''absolutely NO Laws prohibiting the participation in the program and if people can follow the simple instructions, they are bound to make some mega bucks with only$25 out of pocket cost''. DUE TO THE RECENT INCREASE OF POPULARITY & RESPECT THIS PROGRAM HAS ATTAINED, IT IS CURRENTLY WORKING BETTER THAN EVER. This is what one had to say: ''Thanks to this profitable opportunity. I was approached many times before but each time I passed on it. I am so glad I finally joined just to see what one could expect in return for the minimal effort and money required. To my astonishment, I received a total of $610,470.00 in 21 weeks, with money still coming in." Pam Hedland, Fort Lee, New Jersey. ============================================ Here is another testimonial: "This program has been around for a long time but I never believed in it. But one day when I received this again in the mail I decided to gamble my $25 on it. I followed the simple instructions and walaa ..... 3 weeks later the money started to come in. First month I only made $240.00 but the next 2 months after that I made a total of $290,000.00. So far, in the past 8 months by re-entering the program, I have made over $710,000.00 and I am playing it again. The key to success in this program is to follow the simple steps and NOT change anything.'' More testimonials later but first, =PRINT THIS NOW FOR YOUR FUTURE REFERENCE= $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ If you would like to make at least $500,000 every 4 to 5 months easily and comfortably, please read the following...THEN READ IT AGAIN and AGAIN!!! $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ FOLLOW THE SIMPLE INSTRUCTIONS BELOW AND YOUR FINANCIAL DREAMS WILL COME TRUE, GUARANTEED! INSTRUCTIONS: =====Order all 5 reports shown on the list below ===== For each report, send $5 CASH, THE NAME & NUMBER OF THE REPORT YOU ARE ORDERING and YOUR E-MAIL ADDRESS to the person whose name appears ON THAT LIST next to the report. MAKE SURE YOUR RETURN ADDRESS IS ON YOUR ENVELOPE TOP LEFT CORNER in case of any mail problems. === When you place your order, make sure you order each of the 5 reports. You will need all 5 reports so that you can save them on your computer and resell them. YOUR TOTAL COST $5 X 5=$25.00. Within a few days you will receive, vie e-mail, each of the 5 reports from these 5 different individuals. Save them on your computer so they will be accessible for you to send to the 1,000's of people who will order them from you. Also make a floppy of these reports and keep them on your desk in case something happens to your computer. IMPORTANT - DO NOT alter the names of the people who are listed next to each report, or their sequence on the list, in any way other than what is instructed below in step '' 1 through 6 '' or you will loose out on majority of your profits. Once you understand the way this works, you will also see how it does not work if you change it. Remember, this method has been tested, and if you alter, it will NOT work !!! People have tried to put their friends/relatives names on all five thinking they could get all the money. But it does not work this way. Believe us, we all have tried to be greedy and then nothing happened. So Do Not try to change anything other than what is instructed. Because if you do, it will not work for you. Remember, honesty reaps the reward!!! 1.... After you have ordered all 5 reports, take this advertisement and REMOVE the name & address of the person in REPORT # 5. This person has made it through the cycle and is no doubt counting their fortune. 2.... Move the name & address in REPORT # 4 down TO REPORT # 5. 3.... Move the name & address in REPORT # 3 down TO REPORT # 4. 4.... Move the name & address in REPORT # 2 down TO REPORT # 3. 5.... Move the name & address in REPORT # 1 down TO REPORT # 2 6.... Insert YOUR name & address in the REPORT # 1 Position. PLEASE MAKE SURE you copy every name & address ACCURATELY! ============================================ **** Take this entire letter, with the modified list of names, and save it on your computer. DO NOT MAKE ANY OTHER CHANGES. Save this on a disk as well just in case if you loose any data. To assist you with marketing your business on the internet, the 5 reports you purchase will provide you with invaluable marketing information which includes how to send bulk e- mails legally, where to find thousands of free classified ads and much more. There are 2 Primary methods to get this venture going: METHOD # 1: BY SENDING BULK E-MAIL LEGALLY ============================================ Let's say that you decide to start small, just to see how it goes, and we will assume You and those involved send out only 5,000 e-mails each. Let's also assume that the mailing receive only a 0.2% response (the response could be much better but lets just say it is only 0.2%. Also many people will send out hundreds of thousands e-mails instead of only 5,000 each). Continuing with this example, you send out only 5,000 e- mails. With a 0.2% response, that is only 10 orders for report # 1. Those 10 people responded by sending out 5,000 e-mail each for a total of 50,000. Out of those 50,000 e-mails only 0.2% responded with orders. That's=100 people responded and ordered Report # 2. Those 100 people mail out 5,000 e-mails each for a total of 500,000 e-mails. The 0.2% response to that is 1000 orders for Report # 3. Those 1000 people send out 5,000 e-mails each for a total of 5 million e-mails sent out. The 0.2% response to that is 10,000 orders for report #4. Those 10,000 people send out 5,000 e- mails each for a total of 50,000,000 (50 million) e-mails. The 0.2% response to that is 100,000 orders for Report # 5. THAT'S 100,000 ORDERS TIMES $5 EACH=$500,000.00 (half million). Your total income in this example is: 1..... $50 + 2..... $500 + 3.....$5,000 + 4 . $50,000 + 5..... $500,000 ........ Grand Total=$555,550.00 NUMBERS DO NOT LIE. GET A PENCIL & PAPER AND FIGURE OUT THE WORST POSSIBLE RESPONSES AND NO MATTER HOW YOU CALCULATE IT, YOU WILL STILL MAKE A LOT OF MONEY ! ============================================ REMEMBER FRIEND, THIS IS ASSUMING ONLY 10 PEOPLE ORDERING OUT OF 5,000 YOU MAILED TO. Dare to think for a moment what would happen if everyone or half or even one 4th of those people mailed 100,000e-mails each or more? There are over 150 million people on the Internet worldwide and counting. Believe me, many people will do just that, and more! METHOD # 2 : BY PLACING FREE ADS ON THE INTERNET ============================================ Advertising on the net is very very inexpensive and there are hundreds of FREE places to advertise. Placing a lot of free ads on the Internet will easily get a larger response. We strongly suggest you start with Method # 1 and METHOD # 2 as you go along. For every $5 you receive, all you must do is e-mail them the Report they ordered. That's it. Always provide same day service on all orders. This will guarantee that the e-mail they send out, with your name and address on it, will be prompt because they can not advertise until they receive the report. =========== AVAILABLE REPORTS ============ ORDER EACH REPORT BY ITS NUMBER & NAME ONLY. Notes: Always send $5 cash (U.S. CURRENCY) for each Report. Checks NOT accepted. Make sure the cash is concealed by wrapping it in at least 2 sheets of paper. On one of those sheets of paper, Write the NUMBER & the NAME of the Report you are ordering, YOUR E-MAIL ADDRESS and your name and postal address. PLACE YOUR ORDER FOR THESE REPORTS NOW : ============================================ REPORT # 1: "The Insider's Guide to Advertising for Free on the Net" Order Report #1 from: Anthony Hayes P.O.Box 111 Ashmore, Queensland Australia 4214 __________________________________________________ REPORT # 2: "The Insider's Guide to Sending Bulk e-mail on the Net" Order Report # 2 from: WCF Unit 1002 / 43 Garfield Terrace Surfers Paradise, Queensland Australia 4217 _________________________________________________ REPORT # 3: "Secret to Multilevel Marketing on the Net" Order Report # 3 from : Daniel Lee 306 Spring Street Hendersonville, NC 28739, USA __________________________________________________ REPORT # 4: "How to Become a Millionaire Utilizing MLM & the Net" Order Report # 4 from: Mike Manegold Sonnenbergstrasse 40 CH-8800, Thalwil (Switzerland). _______________________________________________ REPORT #5: "How to Send Out one Million e-mails for Free" Order Report # 5 from: M.G. 7143 Hillside Dr. W. Bloomfield, MI 48322-2847, USA __________________________________________________ $$$$$$$$$ YOUR SUCCESS GUIDELINES $$$$$$$$$$$ Follow these guidelines to guarantee your success: === If you do not receive at least 10 orders for Report #1 within 2 weeks, continue sending e-mails until you do. === After you have received 10 orders, 2 to 3 weeks after that you should receive 100 orders or more for REPORT # 2. If you did not, continue advertising or sending e-mails until you do. === Once you have received 100 or more orders for Report # 2, YOU CAN RELAX, because the system is already working for you, and the cash will continue to roll in ! THIS IS IMPORTANT TO REMEMBER: Every time your name is moved down on the list, you are placed in front of a Different report. You can KEEP TRACK of your PROGRESS by watching which report people are ordering from you. IF YOU WANT TO GENERATE MORE INCOME SEND ANOTHER BATCH OF E-MAILS AND START THE WHOLE PROCESS AGAIN. There is NO LIMIT to the income you can generate from this business !!! ============================================ FOLLOWING IS A NOTE FROM THE ORIGINATOR OF THIS PROGRAM: You have just received information that can give you financial freedom for the rest of your life, with NO RISK and JUST A LITTLE BIT OF EFFORT. You can make more money in the next few weeks and months than you have ever imagined. Follow the program EXACTLY AS INSTRUCTED. Do Not change it in any way. It works exceedingly well as it is now. Remember to e-mail a copy of this exciting report after you have put your name and address in Report #1 and moved others to #2 ...........# 5 as instructed above. One of the people you send this to may send out 100,000 or more e-mails and your name will be on every one of them. Remember though, the more you send out the more potential customer you will reach. So my friend, I have given you the ideas, information, materials and opportunity to become financially independent. IT IS UP TO YOU NOW ! ======== MORE TESTIMONIALS ============ "My name is Mitchell. My wife, Jody and I live in Chicago. I am an accountant with a major U.S. Corporation and I make pretty good money. When I received this program I grumbled to Jody about receiving ''junk mail''. I made fun of the whole thing, spouting my knowledge of the population and percentages involved. I ''knew'' it wouldn't work. Jody totally ignored my supposed intelligence and few days later she jumped in with both feet. I made merciless fun of her, and was ready to lay the old ''I told you so'' on her when the thing didn't work. Well, the laugh was on me! Within 3 weeks she had received 50 responses. Within the next 45 days she had received total $ 147,200.00 ........... all cash! I was shocked. I have joined Jody in her ''hobby''. Mitchell Wolf C.P.A., Chicago, Illinois ========================================== ''Not being the gambling type, it took me several weeks to make up my mind to participate in this plan. But conservative that I am, I decided that the initial investment was so little that there was just no way that I wouldn't get enough orders to at least get my money back''. '' I was surprised when I found my medium size post office box crammed with orders. I made $319,210.00 in the first 12 weeks. The nice thing about this deal is that it does not matter where people live. There simply isn't a better investment with a faster return and so big." Dan Sondstrom, Alberta, Canada =========================================== ''I had received this program before. I deleted it, but later I wondered if I should have given it a try. Of course, I had no idea who to contact to get another copy, so I had to wait until I was e-mailed again by someone else.........11 months passed then it luckily came again...... I did not delete this one! I made more than $490,000 on my first try and all the money came within 22 weeks." Susan De Suza, New York, N.Y. ============================================ ''It really is a great opportunity to make relatively easy money with little cost to you. I followed the simple instructions carefully and within 10 days the money started to come in. My first month I made $20,560.00 and by the end of third month my total cash count was $362,840.00. Life is beautiful, Thanks to the internet.". Fred Dellaca, Westport, New Zealand ============================================ ORDER YOUR REPORTS TODAY AND GET STARTED ON 'YOUR' ROAD TO FINANCIAL FREEDOM ! =========================================== If you have any questions of the legality of this program, contact the Office of Associate Director for Marketing Practices, Federal Trade Commission, Bureau of Consumer Protection, Washington, D.C.

It's really well designed, I like it. Normally, GNU prefer to use just the HTML 2.0 standard. This ensures that pages can be read even on text mode browsers like lynx. I notice you've used DIVs and so on... any chance you could convert these to something a bit more HTML 2.0? If you can't I suggest you do this: - create a directory for crypto on the classpathX website (follow the example of JAXP). - subdivide the webpage into separate sections. - ensure the main crypto index page is HTML 2.0 compliant. > i didnt check in the javadoc api yet, nor the release. the javadoc stuff, > will go in the api/ folder. i'm not quite sure yet where the release will > go or if a copy should be also checked-in with this page. The release will go on the ftp server. If you let me know about when you're ready to release then I will check out your code and build it (as a final sanity check) and put it up on the ftp server. That's why you need a target to produce the tar file (see the gnu coding standards for info). > finally what probably is missing is a link from the classpathx main page to > this one. should i be doing this or should i leave it to you? Leave it to me.. when we've resolved this HTML version issue I'll put the link in. This is all coming together really well! Well done!

No comments yet on the real guts -- though from the look of it I won't have many complaints, clean and regular crypto code is usually a very good sign! So here's a random set of questions and comments that came to mind as I skimmed what CVS told me. Some peripheral points first leaped out at me: - Coding style ... three space indents? No tabs? And Hungarian "IamAnInterface" notation? Yoiks! I don't like even one of those, sorry. - PDFs in the docs. DocBook XML where possible, please. Though since these are original specs, I suspect that's not a real option. Does CVS need to have those? (I hate TexInfo equally ... DocBook at least turns into good HTML, though the MathML output may be a bit lacking just now.) - javadoc. The links to the PDFs were all broken, and there were no "package.html" files to describe why each package is there and how to use it. - License ... LGPL, not "GPL + library exception". Maybe not an immediate issue, but static linking will increasingly matter. OK, non-peripheral points: functionality. Seems to be a strange selection in this first code drop. - Seems that widely used hashes (MD5, SHA1; maybe MD2) aren't there. - Block ciphers. Again, common ones are not there yet. DES, 3DES-EDE; likely Blowfish; maybe CAST128. - And of less immediate concern (to me), stream ciphers. ARCFOUR, maybe AES in stream modes, and so on. - Looks like the factory always runs selftests on whatever it returns. (gnu.crypto.cipher.CipherFactory). That should be conditionalized on a "if doing development" static final boolean flag, so it normally doesn't happen. - No public key crypto support (RSA, D-H, etc) or digital signature support. Again, why? The PKCS7 doc there strongly suggests it'll be added, along with lots of BER/DER style utilities for cert and public/private key management ... That's just first reactions from a look at the code. Of course I like the fact that ciphers are interfaces and there's none of that silly overhead of a java security layer to slow down calls past abstract method overhead, so from that perspective the API framework starts out immediately on the right foot. And since secure key storage is a quick hack [NOT!] I can easily understand adding it later, after some hardware hooks have been reasonably prototyped. A lot of that is just wondering what the direction for this code is expected to be. I'll assume that what's there is a good start, but since it doesn't do what I'd first need to be done ... :) Not having support for today's most widely used cryptographic algorithms seems to me like it'll be an adoption problem, and I hope the plan is to make sure that several of those algorithms get added before the first (beta?) release. - Dave p.s. I'm not currently subscribed to the list, so please cc me on any responses.

Do you have any experience with it? > I am quite sure I read somewhere that gcj as some tools to convert > javadoc to texinfo, have you heard of that? I have used Docbook, and it is really good. However, docbook doesn't yet have an info maker and info is still the chosen doc platform for GNU. There's good reason for that, docbook may be the new and sexy thing but it still doesn't have the widespread support of info. And in many ways info is superior (it's lighter for one thing). The GNU project is working on a javadoc -> info tool. That is being done by the Classpath Tools project, which is part of Classpath. Hopefully we will eventually have docbook -> info too, I'm sure someone is working on it somewhere.

When there is an info generator for docbook I'll be happy for people to have their documentation in docbook, until then I meerly tolerate it /8-> I don't think the PDFs are generated by the project. If they are we must use something else. We might still have to ditch them and link to them elsewhere (which seems sensible anyway, if they're someone else's files). > - javadoc.

I understand your reasons... I'm just nervous of distributing PDF files (a proprietary format) from non-GNU sources. I hope you understand. If you can get the author's permission I will _consider_ allowing their hosting on the GNU site. If not, we will have to manage the movement of the files (perhaps by meerly quoting them).

And the counter-argument is that "four spaces" is much more common, doesn't fight against standard 8-space tabstops, and is still "nicer" than "indent == tab" for cases where nested code constructs "must" be used. And I'll note that Linux coding style certainly says "indent == tab", and notes that when that's awkward, the algorithm is the problem, not the coding standard. That tends to be very true, in my observation. Kernel code, like crypto code, is a domain where "simple is better" normally wins against the more "deadline oriented" application domains where "done now is better" wins ... it's "done now" that argues against restructuring code to get rid of excessive nesting/indentation, and argues for narrow indents. (80/4 = max 20 levels/line, 80/3 = 26, either is too complex...) Not that I want to start such style flamewars ... on the other hand I think it's completely reasonable to say "three spaces" or "no tabs" are guidelines that I've never subscribed to. And I'll criticize them every time it comes up, particularly when they're added as exceptions to guidelines that are otherwise largely reasonable, since such style guidelines do add up to > As for tabs, space is the lowest common denominator between editors. > The brain dead ones display 8 spaces for TAB!!! and the good ones can > always be configured to emulate tabs with spaces. Displaying 8 spaces for tabstops is not the same as storing them that way. Some editors will silently correct spelling "mistakes" for you too, and store the results. I don't like either behavior. In both cases using a Real Text Editor is a reasonable requirement. Think of tabs as an 8-to-1 compression scheme built in to the standard text file format. > Many projects require "space only" for that reason actually (Apache projects). The original motivation I heard for that was that a number of early contributors didn't want to switch from Win32 editors which, to this day, are often unable to handle tabbing correctly. (MSFT discourages widespread use of monospaced fonts and "ASCII art" tools. Never mind that interop with other operating systems gets worse that way.) Many non-Apache projects still expect that Real Text Editors will be used ... which know how to handle tabs! :) - Dave From J.Frazur@finnexpo.fi Fri Dec 14 09:21:18 2001 Received: from [61.144.180.47] (helo=mysvr.meiyang.com.cn) by fencepost.gnu.org with smtp (Exim 3.22 #1 (Debian)) id 16EtDB-0003Y4-00 for ; Fri, 14 Dec 2001 09:21:18 -0500 Received: from mail.finnexpo.fi by mysvr.meiyang.com.cn; Fri, 14 Dec 2001 22:24:50 +0800 From: "J.Frazur@finnexpo.fi" To: "8490@lycos.com" <8490@lycos.com> Message-ID: <1008361117.0452675782@mail.finnexpo.fi> MIME-Version: 1.0 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable X-RBL-Warning: (inputs.orbz.org) Open relay.

I'd rather not dictate the use ANT across the board... if we move to that gradually that would be fine. I still prefer Autoconf/Make because that is the GNU standard and because it handles native code better... given the importance of GCJ in the "strategy" native code may become important. Having said that I think ANT will become important as it matures and more java programmers come to GNU from other environments. > if any other project/team-leader is willing to adopt ANT, i'm happy to help > so we can harmonise the use of ANT across multiple projects.

However... apparantly it doesn't work on cygwin. I suspect it is because I also have to add double quotes all over the place, something like: jikes -classpath "pkg1@PS@pkg2" ... to prevent the shell from resolving the semicolon as the "end of command" character. It used to work on cygwin but I haven't try it for few weeks.

The trouble is automake (the version that widely installed) has some issues... my bodged makefile is not actually that much work and therefore I don't mind maintaining it until automake becomes a realistic option. I wouldn't object to any project using automake as long as they maintain it themselves. But on the other hand my bodge makefile does the job (or can do the job) quite well.

We have adopted the second convention; the octet on position n is the nth leftmost octet rather than the (n+1)st leftmost octet. The length of the PS string preceding the 01 octet is emLen-hLen-sLen-2, so the 01 octet is on position emLen-hLen-sLen-1. Yet, I admit that this convention should have been explicitly stated in the document. Best regards, Jakob Jonsson RSA Laboratories ----- Original Message ----- From: "Raif S.

I've just read that you were wondering about some large primes for which java.math.BigInteger.isProbablePrime() returns 'false'. Well, BigInteger has indeed a bug in its primality test. BigInteger runs Miller-Rabin first. If Miller-Rabin returns 'probable prime' for some number, a second test will be made, using Lucas this time. And there is a bug in that Lucas algorithm of BigInteger. I don't know exactly what is is, because a friend of mine examined several primality test algorithms.

The patch which follows (which is longish, but I didn't want to do an attachment---please admonish if this is poor etiquette) is an implementation of Serpent which appears correct in a few tests. It does not, as far as I know, refer to any non-free techniques---is uses some optimized S-box functions found by Dag Arne Osvik which are implemented in a GPL'd ADA implementation from http://www.ii.uib.no/~gisle/serpent.html. The patch is based on a recent CVS checkout and updates the gcj Makefile.{in,am}, the classes Registry and CipherFactory, and adds the Serpent class itself. Classpathx is welcome to use it.

Classpathx is welcome to use it... i'll add the patches during this weekend, along with some classes and algorithms i've been working on (HMAC, UMAC, etc...). btw, do you have (access to) the test vectors for Serpent? we should have a junit test case to exercise and produce/compare some of the test vectors for every algorithm so as to certify correctness (e.g. source/test/cipher/TestOfSquare). thanks again for your contribution + cheers; rsn From mstatic@metastatic.org Thu Jun 06 18:45:57 2002 Received: from ludo.dreamhost.com ([66.33.197.214]) by fencepost.gnu.org with esmtp (Exim 3.34 #1 (Debian)) id 17G60z-0001zh-00 for ; Thu, 06 Jun 2002 18:45:57 -0400 Received: from gradius.dreamhost.com (gradius.dreamhost.com [66.33.197.13]) by ludo.dreamhost.com (Postfix) with ESMTP id 3ECCB5298B; Thu, 6 Jun 2002 15:45:56 -0700 (PDT) Received: from localhost (mstatic@localhost) by gradius.dreamhost.com (8.11.0/8.9.3/Debian 8.9.3-21) with ESMTP id g56Mjtx28069; Thu, 6 Jun 2002 15:45:56 -0700 X-Authentication-Warning: gradius.dreamhost.com: mstatic owned process doing -bs Date: Thu, 6 Jun 2002 15:45:55 -0700 (PDT) From: Casey Marshall X-X-Sender: mstatic@gradius.dreamhost.com Reply-To: Casey Marshall To: "Raif S.

The implementation appears correct (at least, my faith in it is a bit stronger). I'll see about putting together a test case for it, however. Also, a question: it appears as though the library is working with the assumption that all of its ciphers are not stateful, ie something like: cipher.encryptBlock(pt, 0, ct, 0); cipher.decryptBlock(ct, 0, cpt, 0); will result in pt==cpt (and this is the case, I think, with all the current cipher algorithms, as well as most others that I'm familiar with). This isn't strictly true, for example, for ARCFOUR, whose s-boxes evolve over time. So would stateful ciphers need to be careful about this (e.g. keeping s-boxes for encryption and decryption), or could one assume that this is not, in practice, the case? (Bonus: yes, ARCFOUR is a stream cipher, so would a seperate interface (IStreamCipher) be a solution?)

So would stateful ciphers need to be careful about this (e.g. > keeping s-boxes for encryption and decryption), or could one assume that > this is not, in practice, the case? the thing to clarify here is that: a. both types of ciphers are stateful, yet b. one type (the symmetric-key block-ciphers eg. aes, rijndael, serpent, and all gnu.crypto.cipher classes) is invertible, while the other (not yet implemented in gnu.crypto) is not. > (Bonus: yes, ARCFOUR is a stream cipher, so would a seperate interface > (IStreamCipher) be a solution?) yes! as far as i know, it's the only solution. for other types of stream ciphers, have a look at some newly designed stream ciphers, submitted in the NESSIE project --see https://www.cosic.esat.kuleuven.ac.be/nessie/workshop/submissions.html. > > Cheers, > > -- > Casey Marshall < rsdio@metastatic.org > http://metastatic.org/ > > > > _______________________________________________ > Classpathx-crypto mailing list > Classpathx-crypto@gnu.org > http://mail.gnu.org/mailman/listinfo/classpathx-crypto > From mstatic@metastatic.org Sat Jun 08 19:36:53 2002 Received: from ludo.dreamhost.com ([66.33.197.214]) by fencepost.gnu.org with esmtp (Exim 3.34 #1 (Debian)) id 17GplM-0005Cm-00 for ; Sat, 08 Jun 2002 19:36:52 -0400 Received: from gradius.dreamhost.com (gradius.dreamhost.com [66.33.197.13]) by ludo.dreamhost.com (Postfix) with ESMTP id 2445052836 for ; Sat, 8 Jun 2002 16:36:50 -0700 (PDT) Received: from localhost (mstatic@localhost) by gradius.dreamhost.com (8.11.0/8.9.3/Debian 8.9.3-21) with ESMTP id g58NaoN00311 for ; Sat, 8 Jun 2002 16:36:50 -0700 X-Authentication-Warning: gradius.dreamhost.com: mstatic owned process doing -bs Date: Sat, 8 Jun 2002 16:36:49 -0700 (PDT) From: Casey Marshall X-X-Sender: mstatic@gradius.dreamhost.com Reply-To: Casey Marshall To: "classpathx-crypto@gnu.org" Message-ID: MIME-Version: 1.0 Content-Type: MULTIPART/MIXED; BOUNDARY="1439763957-1167906377-1023579409=:31164" Subject: [Classpathx-crypto] TestOfSerpent Sender: classpathx-crypto-admin@gnu.org Errors-To: classpathx-crypto-admin@gnu.org X-BeenThere: classpathx-crypto@gnu.org X-Mailman-Version: 2.0.9 Precedence: bulk List-Help: List-Post: List-Subscribe: , List-Id: List-Unsubscribe: , List-Archive: This message is in MIME format.

It runs all the variable-key and variable-text known-answer tests, and the first ten of each of the monte carlo tests provided in the Serpent team's submission. It also runs the BaseCipher's default symmetry test. This version comes from a test suite that tests all known-answer and all monte carlo tests -- which seemed a bit excessive. It is available at: http://www.metastatic.org/src/serpent-test-full.tar.gz It is 117 kilobytes compressed, and is slow. I figured that this version provided a good enough compromise, and can be trimmed even further by simply deleting answers from the bottoms of the test arrays.

Did you look at the automakejar stuff? It has been recieved with enthusiasm on other GNU java projects and hopefully will become something of a standard for us.

Nistxxx tools _emit_ the test vectors, but they also include the code to verify the inverse operation of what they generate. re-factoring that code and re-using your patterns (from TestOfSerpent) would allow: a. ending up with new tools (or added functionality to the existing ones) that _read_ the conformance test vectors and verify them, this time instead of _writing_ them out. b. exposing some methods in these tools, or have'em all use common Helper(s) to do their job and making writing TestOf as simple as feeding the test-case a collection of files (or a directory where those files would be found). does this make sense? cheers; rsn From mstatic@metastatic.org Tue Jun 11 23:10:05 2002 Received: from ludo.dreamhost.com ([66.33.197.214]) by fencepost.gnu.org with esmtp (Exim 3.34 #1 (Debian)) id 17HyWK-00046K-00 for ; Tue, 11 Jun 2002 23:10:04 -0400 Received: from gradius.dreamhost.com (gradius.dreamhost.com [66.33.197.13]) by ludo.dreamhost.com (Postfix) with ESMTP id 6A1815283B for ; Tue, 11 Jun 2002 20:10:03 -0700 (PDT) Received: from localhost (mstatic@localhost) by gradius.dreamhost.com (8.11.0/8.9.3/Debian 8.9.3-21) with ESMTP id g5C3A3F05164 for ; Tue, 11 Jun 2002 20:10:03 -0700 X-Authentication-Warning: gradius.dreamhost.com: mstatic owned process doing -bs Date: Tue, 11 Jun 2002 20:10:03 -0700 (PDT) From: Casey Marshall X-X-Sender: mstatic@gradius.dreamhost.com Reply-To: Casey Marshall To: "classpathx-crypto@gnu.org" Message-ID: MIME-Version: 1.0 Content-Type: MULTIPART/MIXED; BOUNDARY="1439763957-2107575277-1023851403=:4424" Subject: [Classpathx-crypto] MD4 Sender: classpathx-crypto-admin@gnu.org Errors-To: classpathx-crypto-admin@gnu.org X-BeenThere: classpathx-crypto@gnu.org X-Mailman-Version: 2.0.9 Precedence: bulk List-Help: List-Post: List-Subscribe: , List-Id: List-Unsubscribe: , List-Archive: This message is in MIME format.

It was quite easy to make a patch for Classpathx. Classpathx is welcome to incorporate it, if you like (I know MD4 is not used as much as other algorithms).

It would certainly make life easier. However, Raif does not have a GNU system available to him, if someone donated one, I'm sure he'd use it. In the mean time he's doing excellent work contributing to the ClasspathX project. Nic Ferrier ClasspathX Maintainer.

One thing that is good, the cvs diff at savanah does pick up the difference for modified files. That is if you change the content of a file and also convert it to unix ending, the file will be fully updated. Strangely enought, it does not work if the only change is a convertion to Unix ending! > >In fact, it would propably be better if ALL the source code had the Unix > >ending, as the Primary target of the gnu project is GNU / Unix systems > >rather than Windows platforms. > > if you check the java sources, you'll notive that this is the case. i > think the tool i use wants to be too smart when it comes to (what i > considers) plain text files. I did open a few files in the test package while working on the JUnit compilation. Some are actually a mix up of DOS and Unix ending (most lines with DOS ending, few with Unix). Anyway, it does not seem to matter much for the java sources, shell scripts and makefiles are more critical. > >PS: I'll start working on the JUnit test harness for GCJ soonish. > > good to hear. > It does work! I ran the test suite, it reports: 101 tests, 13 failures. The failures are not really failures, they all seem to boil down to java.security.Exception from requests for algorithms not available in the gcj standard lib (as opposed to jdk). I need to work more on the makefile before I am ready to commit the update.

The class loads test files with the `getResource' method of java.lang.Class, so the vector files can simply be put into gnu-crypto-test.jar. The patch only adds the class itself, and updates the build scripts and test.cipher.AllTests. I didn't include the test files for the three AES submitted ciphers in Classpathx, because they're probably far too big for this mailing list. I've also noted that in the file `Makefile.in' there is a line that says `gnu/crypto/mac/UMash32.java' which I'm guessing should have read `gnu/crypto/mac/UMac32.java'.

having hard-coded values that must be processed correctly for the test to pass, works around the fact that TestOfNistVectors does not fail if it cannot locate the files it is expecting. besides, having hard-coded values inside the test-case, allows application of the (more or less) same pattern to non-NIST ciphers. i'd go with (c). * if we go with (b) or (c), how many hard-coded test vectors should we use? --all of them is out of the question because of size and speed. theoretically one value should be enough, but 3 is more "re-assuring." * should there be any special criteria for selecting the agreed number of test-vectors? or throwing a dice would suffice? * once we have coded those TestOfxxx for our ciphers. should we still keep the selfTest() method in the API and implementations? in its actual form the setlfTest() for the ciphers only test for symmetry, which may be true even for incorrectly implemented ciphers. in other words it's almost useless! we should change it to either (a) something similar to the selfTest() of hash algorithms, (b) something similar to the TestOfxxx discussed above with some hard-coded test vectors, or (c) get rid of it altogether! * if we get rid of the selfTest() method in the API, how can we guarrantee that noone/nothing would replace our "tested" implementations with their (probably) insecure/leaking ones? would a signed jar be enough? * the test vectors generated by, at least, the NistKat and NistMCT tools should be included in the distribution, since they are used by the TestOfNistVectors, which (a) if amended to be more rigourous, and (b) passes all its tests for the test vector files, would constitute a comprehensive "bill-of-health" for the correctness of a cipher's implementation. relying on the NistKat and NistMCT tools to generate them in-situ is not a valid option IMO. a conscientious user would download these test vectors from a different source (NIST itself, the home page of the algorithm designers, or a trustworthy site/distribution), and only then run the TestOfNistVectors over them. so am i contradicting myself? no. am i putting more stringent conditions on what to distribute and how to distribute it? may be. let me explain. + the NistKat and NistMCT tools are used only for (a) generating test vectors for new cipher implementation, and (b) for bootstraping the process. + once the test vector files are generated, they are "certified" (by a process which i still dont know how). the end result would be a signed-jar for each of the NIST-compatible algorithms; eg. aes-tv.jar for the AES test vectors. + the gnu-crypto.jar is signed. + the TestOfNistVectors, or similar class, would use the cipher implementation from the gnu-crypto signed jar with the test vectors from the cipher's test vectors signed jar to assert the correctness of that cipher. does it make sense? * whatever we come with from the discussion of the previous point, a third jar, grouping the test vectors, and separate from the gnu-crypto.jar and gnu-crypto-test.jar should be considered. comments and suggestions are welcome + cheers; rsn From mstatic@metastatic.org Mon Jun 24 03:35:45 2002 Received: from ludo.dreamhost.com ([66.33.197.214]) by fencepost.gnu.org with esmtp (Exim 3.34 #1 (Debian)) id 17MOO0-00019K-00 for ; Mon, 24 Jun 2002 03:35:45 -0400 Received: from gradius.dreamhost.com (gradius.dreamhost.com [66.33.197.13]) by ludo.dreamhost.com (Postfix) with ESMTP id DD8475280F; Mon, 24 Jun 2002 00:35:42 -0700 (PDT) Received: from localhost (mstatic@localhost) by gradius.dreamhost.com (8.11.0/8.9.3/Debian 8.9.3-21) with ESMTP id g5O7Zg906393; Mon, 24 Jun 2002 00:35:42 -0700 X-Authentication-Warning: gradius.dreamhost.com: mstatic owned process doing -bs Date: Mon, 24 Jun 2002 00:35:42 -0700 (PDT) From: Casey Marshall X-X-Sender: mstatic@gradius.dreamhost.com Reply-To: Casey Marshall To: "Raif S.

As far as the number of test cases to hard-code, I would recommend *at least* two of each of the monte-carlo tests, so there is at least one change of key. This is because if a test only does the first monte-carlo test, a problem with endianess *could* sneak by, since the all-zero key looks the same regardless of endianness (this did happen early on when I was working on the Serpent implementation, when I only checked the all-zero key). For the known-answer tests I would recommend using texts/keys where a bit is set somewhere in each byte/nybble/word, to try to cover a range, not just the first few. Other than that I would simply use a Comfortable Round Number. > * once we have coded those TestOfxxx for our ciphers. should we still > keep the selfTest() method in the API and implementations? > > in its actual form the setlfTest() for the ciphers only test for > symmetry, which may be true even for incorrectly implemented ciphers. > in other words it's almost useless! > > we should change it to either (a) something similar to the selfTest() of > hash algorithms, (b) something similar to the TestOfxxx discussed above > with some hard-coded test vectors, or (c) get rid of it altogether! > I would go for encrypting a known text, comparing the ciphertext with a known answer, then decrypting it to see if it results in the plaintext. -- Casey Marshall < rsdio@metastatic.org > http://metastatic.org/ From raif@fl.net.au Mon Jun 24 06:53:28 2002 Received: from int-mail.syd.fl.net.au ([202.181.0.28] helo=delenn.fl.net.au) by fencepost.gnu.org with smtp (Exim 3.34 #1 (Debian)) id 17MREs-0002Y8-00 for ; Mon, 24 Jun 2002 06:38:30 -0400 Received: from fl.net.au (a4-p15.syd.fl.net.au [202.181.2.79]) by delenn.fl.net.au (Postfix) with ESMTP id C137E17FD10; Mon, 24 Jun 2002 20:43:10 +1000 (EST) Message-ID: <3D16F6B8.8060203@fl.net.au> Date: Mon, 24 Jun 2002 20:38:48 +1000 From: "Raif S.

I decided to just use sequential texts (shift one bit to the right each time) instead of random/arbitrary ones. It is simpler to program and to produce tests, and the monte carlo tests exercise the algorithms enough that errors are unlikely to sneak by.

Sorry for the delay! I am stuck with another home project for the moment and don't seem to get anything going! Anyway, this is the output I get from the JUnit test suite under GCJ version: gcc (GCC) 3.2 20020518. From this result, it looks very broken but I don't think it is. All the basic tests from the crypto.tools directory are running just fine. I think that gnu-crypto is essentially working with GCJ. The JUnit test suite is more likely to be badly broken because of missing security classes in GCJ than compilation problems or compiler/runtime bugs. Oli This is only a snippets of the output, I attach the full file as well. ......................................... .................................>>> dss: SEED: d38e1e61cc37f5ffcabfe5da132298286e085b19 >>> dss: counter: 2 >>> dss: q: de09f1902cf484f232fee5d27262372d1c6072d7 >>> dss: p: be6189c7df2a7cdf657a81faa2c809f5c5c9ce4d47ed4021fdb8fd55afc140e6ebc8b1df5defadeb422b9f4964eb6d2958940ee84ed8032ce50ac5b611841f87 >>> dss: g: 6444111a41ad5e86dccb6fbb63a0bc6a1b85b7af338a269a14056cbd8afb9458ba1c6016b14f5331ec6400f2ebd83f0f17cdd54a510050648dd8f5aa3d35ffc .>>> dss: SEED: bd86a3974bc22bd3f08c342361075249ef516797 >>> dss: counter: 56 >>> dss: q: 96460a696d1e361b4840d641c696955314b5d061 >>> dss: p: e4e862371e938d890bb7838bb2d50dd079a384406f28e1d1a719f4d886f7e08b9d4c76fc15976f6793fffe98c9356c93b64eae43551561a0a8446f2c80e66cff >>> dss: g: c1d24777284832cf120427c854866ff270c349aa091834161fea360801f76ed432d7f615732fdaf6df2a4d274a86db58061e48ff1ec39e88385333d9638ed69 F.>>> dss: SEED: d78931c08e94cf508a9121d194823300dcfe900f >>> dss: counter: 417 >>> dss: q: aeefc632ffed90b4103202b8b3c9311eb23009e7 >>> dss: p: 9cab4e49c636313f8bd548aa2bbf79b5049ceedcdd7f130d41b9ab8533f81ca93366fbe619bc0a63a338b49925c44752ea4c35b8840164889cdb21fc54ceeead >>> dss: g: 2a651864ab3b9a2f0a05bb24a1ad72578abecc8160391a9964b6d42a126ae0dd1deb678063e2ddc190d80afbe10ba64225c605735207b16358ab640f88424974 F.>>> dss: SEED: b411c7108639999a028fd5766ba8482a130fbfcb >>> dss: counter: 181 >>> dss: q: bb593e212739720fb3a98fa06818448ce03e5965 >>> dss: p: 886b602f67146f295cf4357e249d70750c86381cb5e2bc8eb195d654bb8869e5595172e967c9d9efd621d2806ad391b15583f01903ded7dc8d84491c68f6ffeb >>> dss: g: 3642955454bc0d9c9b20f6420bd7cfcd9fe6ceeb43212c083eb42cf16d8a44fddd8ecd56f062625a2ac05055ff2eebb86c60a56b62dcbbf53a3ccc9654d31a66 F.E.E.E.E.

First of all be aware that "classpath" and "gcj" don't always share the same code. They are merging differences step by step. In gcj the classes are under: gcc/libjava/java > a simple fix is to replace the following line in the above method (with > 2 arguments) with the following: > > - return getInstance(p.getProperty("MessageDigest." + algorithm), > algorithm, p); > > + // try the name as is > + String className = p.getProperty("MessageDigest." + algorithm); > + if (className == null) { // try all uppercase > + String upper = algorithm.toUpperCase(); > + className = p.getProperty("MessageDigest." + upper); > + if (className == null) { // try if it's an alias > + String alias = p.getProperty("Alg.Alias.MessageDigest." + > algorithm); > + if (alias == null) { // spit the dummy > + throw new NoSuchAlgorithmException(algorithm); > + } > + className = p.getProperty("MessageDigest." + alias); > + if (className == null) { > + throw new NoSuchAlgorithmException(algorithm); > + } > + } > + } > + return getInstance(className, algorithm, p); The gcj implementation of MessageDigest looks the same as classpath. I haven't tried your patch yet. I did try the naive approach of replacing: MessageDigest md = MessageDigest.getInstance("SHA", GNU); ... ... MessageDigest md = MessageDigest.getInstance("WHirlpool", GNU); with: MessageDigest md = MessageDigest.getInstance("SHA-160", GNU); ... ... MessageDigest md = MessageDigest.getInstance("WHIRLPOOL", GNU); In TestOfProvider.java, I now get: java.lang.ClassCastException: gnu.crypto.jce.Sha160Spi cannot be cast to java.security.MessageDigest ... ... java.lang.ClassCastException: gnu.crypto.jce.WhirlpoolSpi cannot be cast to java.security.MessageDigest ???

I have updated the GCJ build accordingly. Both crypto library and JUnit test suite build successfully however Anubis still does not pass its self test! Making the GCJ build mostly useless for now...

I don't think there are any issues anymore. Can you tell me (privately please) who the developers for the project are (in the past as well as now) and where they reside?

I inspected the selfTest() method, and using good old print-out-the-state debugging found out that selfTest() actually passes all of its tests -- ie it gets past the two nested for loops -- but for some reason returns false.

(i'll send you in private an implementation i did for the Serpent's authors for their AES submission that may give you an idea about what i'm talking about). i guess we have to add to our checklist of TODO list before the release the thread-safety issue you raise. when we identify such a case the documentation has to make it clear that it is an issue the user has to be aware of; e.g. something in the class javadoc like:

I'd also prefer if you waited till we had some text about crypto export. However, the maintainers support forum are usually quite slow to respond... the question is do we put the FSF at risk by offering this for download without the text? I guess one of the things we can do is offer it for download from a European country. However, the CVS is in the states and there's not much we can do about that.

GNU Crypto, part of the GNU ClasspathX project, released under the aegis of GNU, is a 100% Java implementation of cryptographic algorithms and tools, and includes a Java Cryptographic Provider implementation to allow its use through the Java JCA framework and APIs. GNU Crypto includes, in addition to the now standard cryptographic primitives (MD5, SHA-1, AES, etc.), implementations of new and experimental cryptographic primitives and transforms such as Universal Hash Algorithms (UMAC32, TMMH-16 v1), the Universal Security Transform (UST), and others. GNU Crypto also includes implementations of some of the accepted (2nd round) NESSIE (New European Schemes for Signatures, Integrity, and Encryption) project such as Anubis, Khazad, Whirlpool, etc. More details on the rationale, and contents of the library can be found on the project's home page at: .

E.g. the downloads link is: Downloads which just scrolls the "Downloads" text to the top of the window (at least in Mozilla 1). The fix is to just remove (or change) the name="" attributes from the anchors at the top of the page. 2) In the "Reference Documentation" section, there could be links for Serpent and MD4. Similarly in the "Test Vectors" section for Serpent. 3) The cipherSpeed and hashSpeed tables should be qualified with how the programs were run (what JVM, what architecture, &c.). Otherwise it looks good to me; nice work. Raif S.

The key setup is still the same as before. The bad news is that it is NOT always faster than the current implementation. When run on Sun's HotSpot VMs (I've tried 1.3.1_04-b02, 1.4.0-b92, and 1.4.1-rc-b19 on Linux) the JIT will refuse to compile the encrypt and decrypt methods, and all en/decrypting is done in interpreted mode. Thus it is not much faster than interpreted mode (my guess is that Sun is terminally too clever for their own good, and their JIT will not compile methods that are too big or take too long to compile). The good news is that with other VMs this implementation is MUCH faster. Kaffe (version 1.0.6, JIT v3) can get ~5.5 MB/s, and a native version produced by GCJ runs at ~8 MB/s (second fastest for encryption, behind Rijndael, and neck-and-neck with Anubis for decryption). If we can come up with a way to make this inlined version more digestible for certain JITs, I think this would be a good implementation for future releases. - -- Casey Marshall < rsdio@metastatic.org

As expected, and not very good. Still, code size for fully inlined encryption & decryption for x86 is less than 6.3k bytes. Key expansion is 3.7k. Java byte code is probably not as compact as x86 code, but surely there is some overhead we could remove? > c. runs almost 20 times slower than the current one! This can be fixed too, as mentioned in my reply to Casey. We just have to work around compiler limitations.

This doesn't appear to affect speed, unless you're encrypting and decrypting in parallel. | b. generates a 54K class file (compared to 14K for the current impl.) | --with Sun's javac compiler. Bigger classes will always result from such extensive unrolling; this version does a bit better (each S-Box is in its own method, and I removed the static sboxI* and transform methods, since they're no longer needed). Once this version has an inlined key setup the static methods can disappear completely. | c. runs almost 20 times slower than the current one! | Because of the JIT. Sun's HotSpot can handle this one better. I was aiming for the following with this version: 1) Keep constant array indices. 2) Keep methods short, so the JIT can handle them. 3) Don't repeat too much code (e.g. there is a one function per S-Box). The results are a good compromise: ~ Sun 1.4.0 GCJ (native) Kaffe 1.0.6 encrypt 4584.8003 KB/s 6262.5254 KB/s 4283.1689 KB/s decrypt 4861.5435 KB/s 6230.0640 KB/s 4662.7871 KB/s (all on an AMD MP 1200). Much better for Sun's VM, a little slower for GCJ and Kaffe, and better than the current version. By the way with this version GNU's Serpent will be faster than BouncyCastle's. | i see some advantages in keeping the current implementation _and_ adding | the new in-lined one as an alternative; say SerpentInLined? (naming | suggestions are welcome) | I wonder if a naming scheme following "SerpentSBoxImpl" or something similar is more appropriate, since what we're talking about here is a particular implementation of "bit-sliced" S-Boxes. | | i'll start a new thread about discussing this alternative in general; | i.e. how can we [re-]write the Factory methods to provide the _optimal_ | implementation. | | i'll also start another thread about collecting and publishing | performance figures which, ultimately may allow us to tailor the | heuristic for selecting one implementation among many, depending on the | host environment. | | | | If we can come up with a way to make this inlined version more | | digestible for certain JITs, I think this would be a good implementation | | for future releases. | | pointers to finding out more about JIT nuts and bolts, anybody? | There's this: which says that HotSpot JITs can take the option -Xmaxjitcodesize. Generated code size is obviously not the problem, since trying the fully inlined version with outrageously huge compiled code sizes results in equivalent performance. I can't find anything relating to time spent in the compiler. Sun has published some books on their JITs, none of which I've seen, though.

    Serpent is a 32-round substitution-permutation network block cipher, * operating on 128-bit blocks and accepting keys of 128, 192, and 256 bits in * length. At each round the plaintext is XORed with a 128 bit portion of the * session key -- a 4224 bit key computed from the input key -- then one of * eight S-boxes are applied, and finally a simple linear transformation is * done. Decryption does the exact same thing in reverse order, and using the * eight inverses of the S-boxes.

    * *

    Serpent was designed by Ross Anderson, Eli Biham, and Lars Knudsen as a * proposed cipher for the Advanced Encryption Standard.

    * *

    Serpent can be sped up greatly by replacing S-box substitution with a * sequence of binary operations, and the optimal implementation depends * upon finding the fastest sequence of binary operations that reproduce this * substitution. This implementation uses the S-boxes discovered by * Dag Arne Osvik, which are * optimized for the Pentium family of processors.

(system properties, command line options, opaque object in Factory methods) comments? suggestions? cheers; rsn -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.1.90 (MingW32) Comment: Que du magnifique iD8DBQE9ejkN+e1AKnsTRiERA1Z2AKD+SrjOHTVhdrm7kzhgKu4GX65FNACg/Grj VGkGYC6LhvMcAll9VWQ/FW0= =zUh1 -----END PGP SIGNATURE----- From rsdio@metastatic.org Sat Sep 07 21:12:16 2002 Received: from list by monty-python.gnu.org with tmda-scanned (Exim 4.10) id 17nqca-0006BY-00 for classpathx-crypto@gnu.org; Sat, 07 Sep 2002 21:12:16 -0400 Received: from mail by monty-python.gnu.org with spam-scanned (Exim 4.10) id 17nqcX-0006B3-00 for classpathx-crypto@gnu.org; Sat, 07 Sep 2002 21:12:15 -0400 Received: from 12-235-115-156.client.attbi.com ([12.235.115.156] helo=blossom) by monty-python.gnu.org with esmtp (Exim 4.10) id 17nqcX-0006Af-00 for classpathx-crypto@gnu.org; Sat, 07 Sep 2002 21:12:13 -0400 Received: from dexter ([192.168.0.2] helo=metastatic.org) by blossom with esmtp (Exim 3.35 #1 (Debian)) id 17nqbq-0003ix-00; Sat, 07 Sep 2002 18:11:30 -0700 Message-ID: <3D7AA380.7010805@metastatic.org> Date: Sat, 07 Sep 2002 18:10:24 -0700 From: Casey Marshall User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20020823 Netscape/7.0 X-Accept-Language: en-us, en MIME-Version: 1.0 To: "Raif S.
