srand EXPR
Sets the random number seed for the rand operator. If EXPR is
omitted, does srand(time). Of course, you'd need something much more
random than that for cryptographic purposes, since it's easy to guess
the current time. Checksumming the compressed output of rapidly
changing operating system status programs is the usual method.
Examples are posted regularly to comp.security.unix.
