This function computes the KRB-FX-CF2 function over its inputs and places the results in a newly allocated keyblock. This function is simple in that it assumes that pepper1 and pepper2 are C strings with no internal nulls and that the enctype of the result will be the same as that of k1 . k1 and k2 may be of different enctypes.
