Re: Where can I find NTLMSSP Spec?

Thanks Henrik for the link. :) Now I got my toy
program to generate the correct responses. I still
have one question though: What does this
des_set_odd_parity do? My toy program doesn't have
code related to it but it still "works". Am I just
lucky that I am using some nice inputs?

Cheers,
Yee Man

    void setup_des_key(unsigned char key_56[],
des_key_schedule ks)
    {
        des_cblock key;

        key[0] = key_56[0];
        key[1] = ((key_56[0] << 7) & 0xFF) |
(key_56[1] >> 1);
        key[2] = ((key_56[1] << 6) & 0xFF) |
(key_56[2] >> 2);
        key[3] = ((key_56[2] << 5) & 0xFF) |
(key_56[3] >> 3);
        key[4] = ((key_56[3] << 4) & 0xFF) |
(key_56[4] >> 4);
        key[5] = ((key_56[4] << 3) & 0xFF) |
(key_56[5] >> 5);
        key[6] = ((key_56[5] << 2) & 0xFF) |
(key_56[6] >> 6);
        key[7] = (key_56[6] << 1) & 0xFF;

        des_set_odd_parity(&key);
        des_set_key(&key, ks);
    }
