how to add custome hash type - Net_Spy - 10-20-2013
Greetings to All,
I wonder how to add custom hash type in hashcat .
Code:
md5(md5($password).9486)Any idea how to add that in hashcat ? Looking forward for your kind response.

There is TRAC on top of this page
RE: how to add custome hash type - philsmd - 10-21-2013
Trac is here and you may need to register if not already done (since trac is seperate from the forum and you need to create a new account there).
The algorithm you want to request is md5(md5($pass).$salt) ... since of course the devs would not add a algorithm with hard-coded constants (9486).
There are already "similar" algorithms, like md5(md5($salt).$pass) - see here .
In theory you could use a dictionary containing only 9486 and an external salt list (-e argument)... but I wouldn't really recommend it since it may be *much* slower than a new hash mode that does it the other way around (i.e. $salt is salt and $pass is the pass): md5(md5($pass).$salt).
Note: if such an algorithm would be implemented you still may need to either use -e for the external salt (in this case only a file containing the number 9486), or you need to append to *each* hash in the hashlist ":9486").

why request a new hash mode when this is vbulletin?

oh, haha, so it is. good eye.
RE: how to add custome hash type - philsmd - 10-21-2013
See http://hashcat.net/wiki/doku.php?id=example_hashes , hashcat supports 2 vbulletin hash modes (both have some restrictions on the salt length etc).
Anyway, by using -m 2611 == vBulletin < v3.8.5 and using either -e or adding :9486 to each line in the hash list it might work (even if it may be better to add an additional hash mode w/ md5(md5($pass).$salt) since also md5(md5($salt).$pass) is already listed/implemented as seperate hash mode).

@epixoip thanks for that idea , but I have about number of hashes to test is there any other way to accomplish it. I've register on trac yet waiting for activation email form their side.Looking forward for your kind response.
