Anyone here is interested on getting the hash password of a drivecrypt image?

Currently I'm trying to find the hashed sha256 and sha1 password from a drivecrypt image so that the password could be tried in bruteforce and/or dictionary attack.

I just got stucked up when drivecrypt calls a kernel side routine to verify the password. For now my solution is to research about how a driveimage works.

It`s very hard. SHA-256 is very cool SHA ! I doubt, that find good reply of your question.
You can see to InsidePro toolkit or google.com utillite.

Good luck!

P.S.: I`m sorry for my English. It`s very bad, but I learn it.

Fuck...

This guy wants to know how to get hashes from DriveCrypt volume file, not how to brute 'em...

Thank you for the reply theCollision and don't worry my english sucks

Anyways Scratch is right about that. But I would a better chance of cracking the hash than cracking the whole image itself since it would be rjaendale, aes, rc6 but I know that the hash would be SHA1 or SHA256. The minimal password for drivecrypt would be 8 characters long and as long as 160 total password is possible. Bruteforcing it would not be easy but I could only try to make a distributed attacked (used lot's of computer to crack the hash).

So far I already got an open source program that works like drivecrypt and hope to analyzed it's kernel routines so I could somehow get to the routine of drivecrypt's driver. Drivecrypt have a header from offset 0 to 9984 (and it is always random for every new container). As I first thought that the hash would be there somewhere in the open but unfortunately drivecrypt encoded it.

Also I have read rumors that it is possible that drivecrypt implemented a pgp like routine that uses a masterpassword in order to mount images. Another rumor is that the password could be overriden. So I just need to confirm those rumors or just do it the old fashion bruteforcing way. So I just need to findout where to get and decode the hashkey.

Once I was on hard work with "DriveCrypt": trying to reanimate some crashed DriveCrypt's encrypted disk. It wasn't the same studing as yours, but I hope it'd help you.

I used to use next installer: dc_setup_302b.exe, size 937 324 bytes.
