* kerberos_v4.c
	Improve the checks that DES keys are being used.
* main.c
	Do not assume that the master key is necessarily a DES key suitable
	for use to initialize the V4 random key generator.  Instead, after
	initializing the DES_CBC_CRC generator, get a random key and use that
	to seed the V4 random key generator.
