I am writing a program on a UNIX system that uses the crypt() function. Now I want to port this program to MS-DOS, but the problem is that I don't have a crypt() function, (source or object code). Who can help me obtain a crypt() function ?? One that runs faster than the standard unix one would also be welcome to speed up the UNIX version as well. Greetings, wsinpvb@eutrc3.UUCP wsinpvb@eutrc3.urc.tue.nl

[request for crypt function] Didn't I read somewhere that Unix encryption was restricted to U.S.A. and not for export? What happens if the function gets in the "wrong" hands through the network? nghiem@walt.cc.utexas.edu !cs.utexas.edu!ut-emx!walt!nghiem

They've had it for years! I've got the source code in C form, written by Andrew S. Tanenbaum, & taken from his book `Computer Networks'. It's Unix crypt() compatible. It's used in his Minix Operating System, a V7 Unix-clone for PCs. Would anybody get upset if I post it? Is it legal? Is Andy's source copyright? Who has the answers?

What happens if the function gets >in the "wrong" hands through the network? Not a lot. Picture this: person who is in another country with his machine on the Internet ftp's the appropriate crypt binary (or source if he has it) via one of his accounts in the US. It's quite probably happened quite a few times; it's not a high-security item. It's just Officially Frowned Upon for some terribly good reason which escapes me at the moment.

What happens if the function gets >in the "wrong" hands through the network? Nothing happens. The UNIX crypt routines (all of them) have long been in the "wrong hands". The export restriction applies to software vendors, primarily because they haven't been able to obtain blanket export licenses from the Commerce Dept. and the cost of doing them one at a time is prohibitive.

[...] Let me confirm (although noone seems to doubt it) that the crypt() facility is not available on UNIX machines in Australia, and I must say I find this circumstance, although petty, a rather gratuitous insult from Uncle Sam. wnv. -- Dr. W.

Crypt(1) has been in my (wrong) hands for a long time, and despite our current Prime Minister's best efforts Canada is still not part of the U.S. Everybody with licenced UNIX source which goes back before the restriction was imposed has it; that includes a lot of people. It is amusing to consider taking the source for crypt.c (all 134 lines of it) down to the Soviet Consulate and see what I could get for it: maybe a bag of seed corn, or a fried egg, or ... -- David Harrison | "God does not play dice with Dept. of Physics, Univ of Toronto | the universe." -- Einstein UUCP: uunet!attcan!utgpu!utfyzx!harrison | "Quit telling God what to BITNET: HARRISON@UTORPHYS | do." -- Neils Bohr
