Federal law prohibits the export of such technology from the USA and Canada. PKWare does have an export version without the data encryption but that disables one of the features that we badly need in software distribution - data file validation. See the docs in PKZ110.EXE for details. You'll have to get the file from your favorite BBS. By the way, you might tell your BBS Sysop that he or she may be in trouble if the BBS has callers from countries other than the USA and Canada and they download PKZ110.EXE. The same goes for CompuServe and GEnie. It's interesting to note that if the Japanese add DES encrytion to their LHarc program we could IMPORT it from Japan but we could not EXPORT it from the USA or Canada. --Keith
