if this is RC4
by Carl Ellison 17 Dec '03

17 Dec '03

Assuming for the moment that alleged-RC4 came from the keyboard of Ron Rivest, my question is whether to look at this as an amateur cipher from a famous cryptologist -- or as a carefully designed cipher from a professional. If it's the latter, we should probably look for some underlying strengths the way the community picked apart S-box design rules years ago. - Carl

art encryption...
by Lile Elam 17 Dec '03

17 Dec '03

Well, it looks like I have to delve into this subject as I should really know what's available for signing art. Some poeple are concerned that art via the net is going to be ripped off, abused, and any other sort of horra you can think of *if* people share digital images of their works via the Internet (WWW, ftp, newsgroups, et all). So, I have been thinking that a way an artist can insure a viewer that the art they are viewing is really that of the artist, the artist can *sign* their art with their private key and others can check it with their public key. Now, the art would be factered into the key generated that others would check with the public key. So, a image file (gif, jpeg, tiff whatever) would be run through a encryption coding that would generate a signage based on the artist's image and their private key. The image would remain unchanged. Then viewers could run the same encyription coding on the image and apply the artist's public key to see if it really *is* their work.... I don't know if this is the best way to do something like this and I sure am not much of a programmer... :) But it would be interesting to find if you think this is possible. Any other ideas on work authenticy would be appreciated. The main goal here is to let people view the work and if they *really* want to make sure the artist posted it, they could check it with PGP... or the like. Hopefully, people could catch art abuse and let the artist know about it. I myself have my art on the net as "share art" and people can do what they like with the images as long as they don't use them commercially without contacting me first. Also if they really alter an image, to say it's been manipulated and the orig can be found at say art.net. I realize that some folks may abuse these images of paintings I have done but I feel that what I gain by sharing makes up for it all. Unfortunately, this isn't the case with other artists and alot of them are not ready for this concept of sharing and letting go. They become terrified that their works might be open to the terrors I have mentioned. I want to give these artists a method that will make them feel more comfortable about sharing digital images.... Such a method will also help shoot down the marketeering, blood sucking, types of slippery jerks I run into who try and scare artists from sharing on the net. One fellow had the nerve to scare two artists away from art.net with copywrite arguments and abuse issues and then in some crazy way, he convenced them to pay him $ to provide the same service with no security messures ither. Blows my mind that they went for it... sigh..... This type of undermining will not help artists and I want to fight back. This jerk also is probably scared of art.net because we are offering to help teach artists how to put their stuff up with html, are offering a free space for them to create and share in, and are asking them to teach others the same. We are wanting to help other sites come up on the net and do the same. We're totally non-profit. This jerk couldn't understand why I would barter a painting for a years worth of Internet connection for art.net. He asked, "What do you get out of it?". I just shook my head... Sigh... thanks for your help in advance and check out "Art on the Net" if you get the chance...

privacy in Unix environment
by Vladimir Z. Nuri 17 Dec '03

17 Dec '03

Hello everyone, here is a question well suited for the c'punks. I'm looking for some kind of utility that will allow script files to be run, to spawn off processes, but will wipe out environment and "ps" info from being read. i.e. imagine that the commands being called must shield their arguments and environment from the "ps" command run on a system. the ideal program would let me run csh scripts but make all the unix commands called (sort, grep, whatever) invisible to other users on my local system. can it be done? note: I am aware of the trick of using symbolic links to hide command names. tx. bye

UNITED STATES HOUSE OF REPRESENTATIVES CONSTITUENT ELECTRONIC MAIL SYSTEM We welcome your inquiry to the House of Representatives Constituent Electronic Mail System. Currently, fortythree Members of the U.S. House of Representatives have been assigned public electronic mailboxes that may be accessed by their constituents. The nature and character of the incoming electronic mail has demonstrated that this capability will be an invaluable source of information on constituent opinion. We are now in the process of expanding the project to other Members of Congress, as technical, budgetary and staffing constraints allow. A number of House committees have also been assigned public electronic mailboxes. The names and electronic mailbox addresses of these committees are listed below after the information about participating Representatives. Please review the list of participating Representatives below, and if the Congressional District in which you reside is listed, follow the instructions below to begin communicating by electronic mail with your Representative.

However, if your Representative is taking part in the project, we request that you send a letter or postcard by U.S. Mail to that Representative at the address listed above with your name and internet address, followed by your postal (geographical) address. The primary goal of this program is to allow Members to better serve their CONSTITUENTS, and this postal contact is the only sure method currently available of verifying that a user is a resident of a particular congressional district. In addition, constituents who communicate with their Representative by electronic mail should be aware that Members will sometimes respond to their messages by way of the U.S. Postal Service. This method of reply will help to ensure confidentiality, a concern that is of upmost importance to the House of Representatives.

yet another use for MD5
by *Hobbit* 17 Dec '03

17 Dec '03

After examining Tripwire and deciding that it was *way* overkill for my own purposes, I decided to cobble together my own minimalist solution to the unix file integrity problem. I call it "L5", for a variety of reasons, and have decided to present it to the community as a Useful Hack. For all I know it may have already been done elsewhere, but I haven't yet seen such a thing mentioned, despite the simple underlying concept. L5 can be FTPed from asylum.sf.ca.us:/pub/hobbit/L5.tar.Z. L5 simply walks down Unix or DOS filesystems, sort of like "ls -R" or "find" would, generating listings of anything it finds there. It tells you everything it can about a file's status, and adds on an MD5 hash of it. Its output is rather "numeric", but it is a very simple format and is designed to be post-treated by scripts that call L5. Here are some of its other features: Filenames come first, making sorting easier. Filenames are delimited in a non-[unix]-spoofable way; ending in "//". The single character after "//" indicates the file type. Scanning stops at device boundaries, so L5 doesn't go slogging through random NFS trees or "tmpfs"es unless you tell it to. You can tell it not to walk any directories lower than the one[s] you handed it as arguments. [It always walks one level of its given arguments.] You can tell it to only print the filenames. If a file looks like a script of some kind, it is shown as type "K" instead of "F". Useful for finding those setuid shell scripts... MD5 hashing can be output in hex, Tripwire's radix64 format, or not at all, as you specify. The hex hash for a given file is the same as that of the CERT "md5check". You can feed it a list of files or directories to check as its standard input. You can have it do its hash *on* standard input. This feature is useful for doing things like "l5 /critical/files | l5" to get a small but secure summary hash. It is small and reasonably fast. Some of it is based on code from Tripwire, but it doesn't use a DBM database and only offers one hash option. The MD5 code, in particular, is the endian-independent version from Tripwire, which builds almost anywhere. Selection of files to ignore certain changes in is undoubtedly less versatile, but you can always filter the output through further scripts before, for example, diffing your "old" system snapshot against your "new" system snapshot. [The rest of this file is in the README that comes with L5.] _H*
