What makes crypt.c better or more desirable than Ward Christensen's
SCRAMBLE.ASM?  His works on both ASCII and binary files and uses
an 8-character key word which is exclusive-or'ed with the data.
It uses a pseudo-random number generator as well, and I believe
does not suffer from the problem of the key being easily spotted
in a field of binary zeros.
