This is the alpha1 release of an extension module for perl5 which provides a perl interface to a DES library. You need a C DES library to link against, of course. If you want a good implementation (or don't have a DES library already), then I can recommend "the Australian libdes" (Eric Young's implementation) available for anonymous ftp from (amongst other places) ftp.ox.ac.uk in /pub/crypto/DES/libdes.tar.93-10-08.gz. If you are using the 5.000 release of perl5, then you'll need to get a newer version of the ExtUtils::MakeMaker extension which is used to convert this extension's Makefile.PL into a suitable Makefile. Documentation for the Des module itself is in pod format in Des.pod. Malcolm Beattie mbeattie@sable.ox.ac.uk 6 Dec 1994
