des_new_random_key(), and des_init_random_number_generator()
from the crypto-us libdes.
While I'm here, fix a serious bug in des_init_random_number_generator()
whereby the accumlated data to be hashed was zero'd *before* actually
being hashed. NOTE: The bug only affects people who are not using the
rnd(4) in-kernel random number generator, and it is worth noting that
the resulting keys are not always the same, but are likely easy to
determine.
