They've had it for years! I've got the source code in C form, written by
Andrew S. Tanenbaum, & taken from his book `Computer Networks'. It's
Unix crypt() compatible. It's used in his Minix Operating System, a
V7 Unix-clone for PCs. Would anybody get upset if I post it?
Is it legal? Is Andy's source copyright? Who has the answers?
