Subject: Re: Vbulletin Hashes not loading

Ok, this made it work.

I have included a username as well this time which formats the hash as follows:

user $dynamic_7$501652a767ad6a888b659fb1957cb063$)!!

then, I crack using:

john -w:wordlist.txt --format=dynamic_7 --field-separator-char=" " hash.txt

Isn't there an easier way to do it?

Based on my understanding, I guess this is happening because I am using dynamic_7 mode instead of dynamic_6. dynamic_7 forces the field separator character to be not a colon.

I wish dynamic formats were just as easy to handle as other hash types like DES, MD5, SHA1 and so on which are implemented in the core version of JTR.

Subject: [john-users] Vbulletin Hashes not loading
I am trying to crack Vbulletin hashes for version < 3.8.5 with a 3 byte salt.

I have formatted the hash as follows:


now, I crack using:

john -w:wordlist.txt --subformat=dynamic_7 hash.txt

hash.txt contains the above hash.

It gives the error, no hashes loaded.

What might be wrong?

Do I need to specify the user id as well in the file and then specify a field-separator-char at the command line?

I thought we could load hashes into john without specifying the username as well.
