encryption algorythm in the export versions. This is becuase at
the time it was illegal to export DES programs.
This was also part marketing, because it made buying a copy in the
U.S. where it was cheaper (or in some cases dongle-free) and taking
it ouverseas a federal crime.
If you consider that a brute force (trying every possible key) attack
on a DES encrypted file was impossible to do in your lifetime on a 486
PC or 68040 macintosh, you can imagine how quickly it can be done on a
I don't know if anyone has actually done it, but writing a program
to do this would not be impossible, nor would running it.

discussion daily, I still don't understand why the people who now own
Corel won't produce an updated version of WordPerfect for Macs. Since
they do it for PCs, and the market share of Macs is growing, it would
seem to make good business sense.
Can Mike Hendriksen give us some information about this?
