In the January 1984 issue of CRYPTOLOGIA is an article which gives a FORTRAN program for LUCIFER, the predecessor of the DES. LUCIFER was MUCH simpler than the DES, but DID use a 128-bit key... If there was any interest I'd be happy to post a 'C' version to net.sources... Richard Outerbridge outer@utcsrgv UofToronto CSRG
