I forgot my password of an encryption Linux partition (dm-crypt without LUKS) and would like to use JtR to crack it. I am new to JtR and am happy about some guiding by you experts. Because it is a partition I don't have any hash available which could be used easily with JtR. Thus I see two ways: 1) Extract a kind of hash from the partition; but I don't know how. Is there any kernel hacker who could give me input on how to do this? 2) Instead I would need to try to mount the partition with each potential password. Unfortunately this would be quite slow. For my understanding the "external mode" of JtR is exactly for such purpose. I could define a few commands to mount the partition and handle the result (success or failure). Unfortunately I did not found much information about such approach. Is there any more documentation about it than the official docs? Please let me know if my assumptions are correct and which advice you have for me.
