Subject: Re: Vbulletin Hashes not loading

Hi NeoFlash,

Here what i do for this type of Hashes.

My hashes lists contain :

501652a767ad6a888b659fb1957cb063$)!!

Salt S├ęparator is "$", like you allready do

& i run : ./john --format=dynamic_6 hashes.txt

Dynamic_6 & 7 have are quite same i think, the only diff', is the size
of the salt..but Dev can confirm or Un_confirm

Look :

dynamic_6   | md5(md5($p).$s)
dynamic_7   | md5(md5($p).$s)

Regards,

Donovan
