If you did everything in an RSAREF-compatible manner, that would help; I think somebody outside the US has written an RSAREF-clone. Some problems include building programs that have generic-callout hooks instead of crypto-specific hooks (so that they don't get bitten by ITAR), while still maintaining reasonable efficiency and convenience. #--- # Thanks; Bill # Bill Stewart, Freelance Information Architect, stewarts@ix.netcom.com # Phone +1-510-247-0664 Pager/Voicemail 1-408-787-1281 #--- # Export PGP three lines a time --> http://dcs.ex.ac.uk/~aba/export/ M0V]N9W)E<W,@<VAA;&P@;6%K92!N;R!L87<@+BXN(&%B<FED9VEN9R!T:&4@ M9G)E961O;2!O9B!S<&5E8V@L(&]R(&]F('1H92!P<F5S<SL-"F]R('1H92!R M:6=H="!O9B!T:&4@<&5O<&QE('!E86-E86)L>2!T;R!A<W-E;6)L92P@( T*

One way to achieve this is to provide multi-layered generic "compression" hooks which get called in this manner: Compress[x](char *bufferin, size_t insize, char *bufferout, size_t *osize); Then you chain several of these by alternating the in/out buffers, say something like this: for (i=0; i<MAXCOMPRESSORS; i+=2) { Compress[i](buffer1,size1,buffer2,&size2); Compress[i+1](buffer2,size2,buffer1,&size1); } To decompress, you'd do something like this: for (i=MAXCOMPRESSORS-1; i; i-=2) { Decompress[i+1](buffer2,size2,buffer1,&size1); Decompress[i](buffer1,size1,buffer2,&size2); } This lets you set up a chain of compressors, each compressing the output of the previous levels. And what you do is allow these compressors to be external to the program! (If one or more of those should be hooks to encrypt, well, hey, that's just a 'bug' ;-) Basically this does C1(C2(C3(C4...CN(text)))))...) to compress the output of the previous compressors. I would reccomend that the last in the set be the encryptors or else all the other compressors would fail. :-) Now, would >THAT< be exportable? =================================================================93======= + ^ + | Ray Arachelian | Amerika: The land of the Freeh. | \-_ _-/ | \|/ |sunder@escape.com| Where day by day, yet another | \ -- / | <--+-->| | Constitutional right vanishes. |6 _\- -/_ 6| /|\ | Just Say | |----\ /---- | + v + | "No" to the NSA!| Jail the censor, not the author!| \/ | =======/---------------------------------------------------------VI------/ / I watched and weeped as the Exon bill passed, knowing that yet / / another freedom vanished before my eyes.

Yeah, this would work for everyone except commercial institutions within the states. They'd have to get a license agreement for RSA. ...alex...

Perhaps we could convince Bill Gates to bundle RSAREF with all his Windoze OS's?
