Mailcrypt nym.alias.net support
by Jeremey Barrett 17 Dec '03

17 Dec '03

-----BEGIN PGP SIGNED MESSAGE----- For those of you who use mailcrypt (Emacs-PGP interface) for email, I have hacked in support for pseudonyms ala nym.alias.net. In fact, the code has nym.alias.net hardcoded for now. I'm gonna add more stuff, but I'm just letting this out as is. This patch affects mailcrypt.el and mc-remail.el. I made these changes to mailcrypt 3.4, so your mileage may vary on other versions. I did this after the C2 party tonight, so typos and bugs are possible. Please email me if bugs are found. "This value is not configureable" does not qualify, I know it's not configureable yet. (BTW there are a couple functions not used, I was doing it one way, then changed my way of thinking, but the code is ok so I left it.) Installing it: o cd to your lisp directory o cat /path/to/the/patch | patch -p0, or something similar (You will need to pgp this message before extracting the patch to get rid of the leading "- " on some lines.) o recompile the .el files, ala: emacs -batch -f batch-byte-compile mc-remail.el emacs -batch -f batch-byte-compile mailcrypt.el Using it: o You _must_ have a remailer chain defined. This does not work with a single remailer (though a chain of length 1 might work). o Compose a message or reply as normal. Once you are done (the message would go out without nyms or remailers or anything if you hit C-c C-c), hit C-c / n. o The first question asks for a remailer chain, it will do completions. o The second question asks for the name of your nym. This is assumed to be @nym.alias.net, DO NOT include @nym.alias.net. If your nym is jimbob(a)nym.alias.net, just answer jimbob. This does not do completions at the moment. Putting your nym in your .emacs file is a bit weird anyway. o You will be asked for a signature for your nym's private key. o The message will be rewritten to send(a)nym.alias.net and then to the remailer chain you chose. o Send it. Hack the code at will, if you make significant enhancements, please email patches to me. Of course there is no warranty of any sort, if it blows up your machine you're out a machine. I will put this on my web page (http://www.veriweb.com/people/jeremey) for those that prefer that. Ok, here's the patch: - ---------------------------------cut here----------------------------------- *** mailcrypt.el Tue Oct 10 12:33:45 1995 - --- /usr/home/jeremey/PGP/mailcrypt-3.4/mailcrypt.el Sat Jan 25 02:45:27 1997 *************** *** 51,56 **** - --- 51,57 ---- (autoload 'mc-sign "mc-toplev" nil t) (autoload 'mc-insert-public-key "mc-toplev" nil t) (autoload 'mc-remailer-encrypt-for-chain "mc-remail" nil t) + (autoload 'mc-remailer-encrypt-for-nym "mc-remail" nil t) (autoload 'mc-remailer-insert-response-block "mc-remail" nil t) (autoload 'mc-remailer-insert-pseudonym "mc-remail" nil t) *************** *** 101,107 **** (define-key mc-write-mode-map "\C-c/b" 'mc-remailer-insert-response-block) (define-key mc-write-mode-map "\C-c/p" !

The Australian regulations are available at: CUSTOMS (PROHIBITED EXPORTS) REGULATIONS - SCHEDULE 13 http://www.austlii.edu.au/au/legis/cth/consol_reg/cer439/sch13.html and: AUSTRALIAN CONTROLS ON THE EXPORT OF DEFENCE AND STRATEGIC GOODS: http://www.adfa.oz.au/DOD/al/iic/excontrl/excohome.htm Crypto software comes under Part 3, Category 5/2 of these regulations. (These documents are in MS Word format) ADFA, for those who are not aware, is the Australian Defence Force Academy, the major tertiary training institute for the defence forces. I have an extract of the key clauses of these regulations if anyone is interested. Briefly, the Australian regulations ban cryptography exports, claiming responsibilities as a party to the Wassenaar Arrangement, although the actual details of the latter regarding crypto seem obscure. However, an export license can be obtained on application to the Defence Ministry. The conditions of such a license are not openly stated, and at least one Australian software company has been refused a license. It would seem that even "public domain" software such as PGP is covered here. Ironically, the international version of PGP is available from the ADFA site at: ftp://ftp.adfa.oz.au/pub/security/pgp263i/ The government attitude to crypto policy generally in Australia is much more relaxed than in the USA. There is a recognition of business and personal need for strong crypto and that a balance needs to be sought between those needs and that of the law enforcement community. Although key escrow has been raised as an issue in some circles, it has not formed part of any government policy as yet. Greg Taylor EFA Crypto Committee

That's a very insightful obeservation. "Cypher punks" are not opposed to the system. They don't want to change the existing social order. They want to join the upper class and enjoy its privileges (such as privacy and anonymity). They don't want to extend these privileges to the "hoi polloi" (unwashed masses). Jim Bell is a boor, but he had some very interesting ideas that upset the "cypher punk" crowd because he advocates dismantling the system they hope to join one day. This reminds me of a U.S. populist politician from the 1930's whose name I forgot, who advocated expropriating individual wealth above $5M. Why did his disenfranchised supporters want to leave the rich with $5M? Because each one hoped one day to have the $5M. Here's the $64K question: if you were approached by a LEA and offered a huge consulting fee to help break a code to obtain evidence in a criminal case, would you do it? I suspect most "cypher punks" would agree both for the money and for the glory, but no one would ask them because very few people on this list can break codes. :-) [No I would not, irrespective of the fee and the nature of the case.] --- Dr.Dimitri Vulis KOTM Brighton Beach Boardwalk BBS, Forest Hills, N.Y.: +1-718-261-2013, 14.4Kbps

Conrad Burns will reintroduce next week his measure to substantially eliminate export restrictions on computer encoding technology, a spokesman for the Senator says. "We are aiming for the 28th (of January) and it will be the same bill as last year," Matt Raymond, spokesman for the Montana Republican, said. President Clinton signed an executive order in November slightly relaxing export controls on encryption technology -- computer programs that use mathematical formulas to scramble information and render it unreadable without a password or software "key." But many in Congress and the computer industry have said the new Clinton policy did not go far enough to lift the Cold War era export limits that classified most encryption programs as munitions.
