  *) DES CBC did not update the IV. Weird.

     [Ben Laurie]

#else

     Look at des.c, cbc3_enc.c etc.: Those rely on that bevaviour of

     des_cbc_encrypt and copy IVs themselves when they have to.

     Either all those have to be changed too, or things must stay as they

     are.

     des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.

     Changing the behaviour of the former might break existing programs --

     where IV updating is needed, des_ncbc_encrypt can be used.

#endif



  *) When bntest is run from "make test" it drives bc to check its

crypto/des/des.h
