For parts of the key setup code, see DES_bs.c.  The rest of it is
inlined into DES_bs_crypt() itself (in 1.7.9).

The plaintext is 0.

The ciphertexts are being computed by that function.

What are you doing this for?  I mean, would you like to reuse the code
in another project (what project?), or would you like to contribute to
JtR development (in what ways?), or something else?
