Some Questions About HashCat
#1
1) How Can i Brute Force many Simple MD5 using GPU?

- Hashcat is using cpu so i dont need it
- oclhashcat-plus does not support Brute Force
- oclhashcat-lite Does Not Support Multiple hashes only single

Maybe with oclhashcat using mask attack like ?d?d?d?d?d?d?d ? But why do i have to specify left and right side for attacking? I think this is a perfomance dropping for brute forcing. Isnt it?

2) Why oclhashcat support vbulletin < 3.8.5 and not vbulletin > 3.8.5 ? I mean whats the big difference between these too. Different salt length i think. So if i have to brute force vbulletin > 3.8.5 i guess CPU version is the only way? (Multi Hashes) Is there any way to brute force them using GPU?

3) Same but for IPB. How can i brute force IPB Hashes using GPU?

4) md5(md5(pass)) is a common hash type. But only simple hashcat and lite version support it. If i want to test multiple md5(md5(pass)) how can i test them using GPU?

5) md5(pass.salt) is a common hash type too. oclhashcat support it as well as oclhash-lite. But how can i test them using wordlists only? If i use oclhashcat for that i have to specify rules for right side too. So simple wordlist attack is impossible?

P.S I know that brute force is not the best way to crack hash, but i want to do just the basic brute force.

Thanks atom! Keep up the good work!
