Subject: Re: dmg2john

Hello,

In the header structure, there is a member,  uint32_t kdf_iteration_count
which holds the iteration count. I've never seen a dmg file having
iteration count different than 1000, but you could check that if the image
has different parameters. I am very interested in the results as well since
I have also fixed 1000 iterations.
