Key Security Question
by Z.B. 17 Dec '03

17 Dec '03

My computer went into the shop a few days ago, and I was unable to take my PGP keys off it before it went in. What are the security risks here? If the repairman chooses to snoop through the files, what would he be able to do with my key pair? Will I need to revoke the key and make a new one, or will I be relatively safe since he doesn't have my passphrase?

> "When I talk to other governments," [David L. Aaron] said, > "they still don't feel that the cat is out of the bag." Aaron's denying that the cat is out of the bag? He was fashionably dressed in a Lion Tamer's outfit, waving a whip, and trying to herd hundreds of small furry mammals to jump through a hoop and back into a clawed-up army duffel-bag! "Cats? Haven't seen any cats around here! Pay no attention to these,umm, Siberian Hamsters that I'm evaluating for export approval." > "Other governments were upset with the 56-bit export allowance. > They said it was going to undermine their national security." On this point, the other governments are correct. It really _is_ tougher to maintain a nation-state when your former subjects can have private conversations with each other and with other governments' former subjects...... And even 56 bits is a start. # Thanks; Bill # Bill Stewart, +1-415-442-2215 stewarts(a)ix.netcom.com # You can get PGP outside the US at ftp.ox.ac.uk/pub/crypto/pgp # (If this is a mailing list, please Cc: me on replies.

I consider it a violation of free speech if the government made "hard crypto" illegal. yes, these cases are generally challenging the publishing aspects of crypto in the US, but this is not what I consider the most important constitutional ingredient in favor of crypto. crypto is essentially a kind of speech, or communication. hence restricting it would be like outlawing a certain foreign language that the government doesn't understand. in my opinion, this is the most important, root case to be made for the use of crypto in this country. publishing crypto algorithms is only a side issue compared to this, imho. so the bottom line is this: crypto regulations can be challenged under the idea that they are restricting freedom of the press, i.e. for academics to discuss algorithms, or it can be challenged under freedom of speech issues, i.e. everyone has the right to use codes for whatever purpose. currently because the regulations prohibit the "export" of crypto code, the first route is the basic challenge that makes the most sense. but I'd like to see the ITAR challenged on the second grounds as well, i.e. as a free speech issue. there's less reason when the gov't is not trying to regulate domestic crypto, but it might be a relevant angle in the export debate. BTW, I understand that there are cases being made by Karn, Junger, and Bernstein, is that correct? with Junger being the most recent? does anyone have web pages dedicated to each one of these? thanks;

How does the current Linux IPSEC release work? Is it a kernel patch or module? A daemon? I'd love to try this out on a local LAN here to see it in action, but don't have too much time these days.

I just got off the phone with PGP sales. Currently PGPMail is only available off if the web site for download. The version on disk will be available sometime mid February. So it looks like if you want it now it is going to cost you $149. If you wait until mid February, you can get it at the lower price (plus $10 shipping and handling). BTW, it does use SSL on the order form, though I have my doubts about the security of sending form data from an insecure page to a secure form cgi.
