SOF ARTICLE

C'punks, I just got off the phone with the Executive Editor of "Soldier of Fortune." I pitched him on a Clipper/strong-encryption article. Because I am such a loyal C'punk, I agreed to write a 2500 word article on spec. If they don't think it will interest their readers, it will be put in the circular file. I'll do my best. S a n d y

remailers
by Black Unicorn 17 Dec '03

17 Dec '03

For some reason I have not been able to get any of the remailers to work with PGP encryption. In addition, the ping figures at the end of the soda finger file don't seem to have changed since I first looked at them some days ago.... is this just me? Is anyone out there chaining with PGP supporting remailers? Could ya drop me a line, preferably with some reply option, and give me a few hints? [sigh]

simple_crypt comparison
by Buckley Collum 17 Dec '03

17 Dec '03

For those who can determine crackability: Recently a message was posted which included source for a chaos-based crypt routine. How does this compare to the one-rotor crypt routine which is found in /bin? I.e., Which one would be easier to crack, and why? I am still learning, so I apologize for the waste of bandwidth if it is intuitively obvious to you. Both source files are attached. Thanks. Buckley Collum

remailer idea... ultimate in offshore siting?
by Phil G. Fraering 17 Dec '03

17 Dec '03

I've been reading the "remailer musings" thread, and it suddenly hit me: why not put the remailer in leo? It probably wouldn't cost _that_ much, and you might make money from the digital postage (if it ever comes out). And if you were wondering, yes, I came up with this while thinking about Teledesic. If the wires are going to be in the sky, why not the machines? Phil

crypt last attempt
by Buckley Collum 17 Dec '03

Problems with mailer on last post, again; Last try. Recently, someone posted a message which contained a chaos-based crypt routine. How, does this compare to the one-rotor crypt routine found in (UNIX) /bin? Which would be easier to crack, and why? Source listings attached. Thanks in advance, and sorry about my mail probs and lack of experience regarding crypto (but, I am learning). (Now, off to kill a mail tool...)

Because that's where his host is, Lefty! Before deciding to see about getting a local access node here, my best bet for private internet access was going to be Portal out in California, and I would have gotten about 30 hrs. access a month (off-peak) for fifty dollars. This is cyberspace. Physical location is irrelevant. Phil

I have an appointment with my State Senator Friday to talk to him about telnet access from basic phone service becoming a State Right of residents. Ma Bell can switch on the ISDN, and people can send their children to public schools with out fear of them being shot in the lunch room. The Community College System, and the University of Wyoming, maintain a plethora of satellite uplinks. The modem pools need to be substantially upgraded, and blocked from out of state long distance calls. With these modifications of the existing system, it is my hope that we can revitalize our economy, and switch from an energy industry based economy to a technologically based economy, with out the infusion of centralized industry moving into a state with limited water resources.

Actually, Low Earth Orbit would be cheaper than geosynchronous, and you could probably piggyback your "telecom experiment" on something like an Iridium launch. _Relatively_ cheap... Phil
