Look at my SSLeay Package (not yet fully functional) at ftp://ftp.uni-mainz.de/pub/Linux/debian-local/
It contains the whole familiy of des commands. (BTW. This is the first Debian package to actually use /opt, so make sure your root partition has enought free space before installing it or make a symlink /opt -> /usr/opt) Yours, Dominik Kubla
