The "mpack" MIME encoder has just been released.
by Derek Upham 17 Dec '03

17 Dec '03

The newsgroup comp.sources.reviewed has just released the sources to "mpack", a utility for encoding binary files into a MIME-compliant format, then mailing them to recepients or posting them to a newsgroup. "munpack", a utility for decoding the files, is also included. The package is supposed to work on MS-DOS and MacOS systems (and it's quite small), so people playing with PGP might be able to get some use out of it.

Help Needed: PGP SIGNED MESSAGE
by Zeek 17 Dec '03

17 Dec '03

{{ Please excuse the interruption. I'm having problems signing a text message with my secret key and creating output that leaves the text message as is but with an ascii signature at the bottom. Or rather, I don't want the message encrypted, I just want the nifty sig attached and email-able. {{ I've done this before using some combination of -sat or something similar but I have since forgotten. This is a rather embarrassing question, I know it has to be a simple switch in the syntax but I spent 2 hours last night and 1 hour this morning trying to figure the damn thing out... learned a few interesting things along the way. Any help would be greatly appreciated. Please reply to me rather than the list. Thank you, -z (kevink)

Hi. I don't know if this address connects to anyone or anything, but I am giving it a shot. I saw an article in Wired and then another one in the 25th anniversary edition of Whole Earth, and wanted to get in touch with you all. #1 Thanks for exisiting....... I am real glad someone is on the side of the angels technologically #2 Please put me on a list to get news. I prowl the newsnet very occasionally, but I don't have a lot of time to do so and I am still climbing up the looooong learning curve of internet. I am quite willing to pay for good info feed from you. #3 Please help me get a clean copy of PGP. I guess thats all I want to throw out unencrypted.....thanks...I want to help. Wes Bradley The return address is my e-mail address at university of colorado where I am a student in aerospace engineering. Thanks again.

I can make life much easier for you simply by mentioning the fact that you can add the line: clearsig = on to your CONFIG.TXT file (Drive:\path\PGP\config.txt). Once you add this line (note to dox writers: add it to the next version release, especially as a #commented line in the default config), then you won't have to worry about adding that pesky argument on the command line ever again!

Re: the public key minefield

Doesn't a patent have to have enough information for a person skilled in the art to construct a prototype? I publish for the first time here my invention. I will patent it with in a years time. Striped Vegetables ---- This isn't enough for anyone to do anything. If I were more specific, I might have something patentable, but then by claims wouldn't be as broad. If you figured out how to make an anti-gravity device. That device would be patentable. The concept of "anti-gravity" device is not patentable. If I could duplicate the effect of your anti-gravity device without using any of the same novel mechanisms. My device would be separately patentable. You seem to have missed my earlier summary of how patents are structured. A separate part of the patent from the claims describes how to build the claimed device. The claims aren't supposed to.

Punks, Does anyone have Postscript or preferably RTF versions of the PGP Docs? I poked around on soda for them but I didn't see any. FRC (please reply direct.. I hate to use the list for this myself.)

Is there a picture of a REAL clipper chip out there anywhere? Someone pointed out that the picture in PopularScience may not be the real thing, just some other chip made by Mykotronics. -nate -- +-------------------------------------------------------------------- | Nate Sammons email: nate(a)VIS.ColoState.Edu | Colorado State University Computer Visualization Laboratory | Finger nate(a)monet.VIS.ColoState.Edu for my PGP key | #include <std.disclaimer> | Always remember "Brazil" +----------------------+
