MS-CACHEv2 hashes - tootech4u - 01-16-2014

I tried to specify a MS-CACHEv2 hash inside of cudaHashcat x64 by typing
-m 1100. When I entered the hash it said that it was too long. I have a 32 character hash. So instead I set it as an MD4 with -m 900. Will this be ok or am I doing something wrong?

no this won't be ok.

MD4 is used inside the DCC1 algorithm which is then part of mscachev2

Overall Algo: PBKDF2(HMAC-SHA1, 10240, DCC1 <<[md4 is used here], username)

You are most likely missing the username component which is used in the salting process.

While MD4 is used within the overall algorithm it accounts for a small part of the actual mscache2 algo, what you are doing will NOT work.

Have you tried loading in the hash with the username? eg hash:username

Thanks it seems to be working!
