Xenix & crypt

[Richard Outerbridge]

This sounds silly.  The DES ("dez") can be freely exported for use
in Canada (by specific exemption from U.S. controls); crypt(1) is
'classified'?  Hmmmm.  Unless, of course, the DES is even weaker 
than crypt(1).  Unlikely.

More to the point it may be a simple matter of bureaucracy. If no
blanket exemption from export controls is available, than the onus may
fall on the exporter to get a permit for each and every exportee.  So
perhaps 'classified' means 'proprietary' (not already in the public
domain - crypt(1): Bell trade secret!) and no one wants to bother getting
formal approval for export to each foreign licensee.

Notice, by the way, ye fans of free trade, that while Canadian export
regulations put no control on cryptographic data exported from here
to south of the 49th, I don't think it works the other way round.  So
much for reciprocity.
