I remember it being in 4.2BSD and adding it to the documentation in
UTek.  All it really does is to modify the key so that the data is
encrypted differently.

I would guess that the folks at Berkeley were having problems with
people looking over their shoulders or running the clist capture
program, so they could alias 'crypt' to 'crypt -s' and snoops seeing
them type 'crypt' would try without luck.
