Post: RE: Error trying a brute force - integer overflow?

Keyspace is stored in a uint64 so the maximum value it can hold is 2^64 - 1. Your keyspace is 2^72.26 .. 2^118.25, so yes, integer overflow. And yes, as rico identified, this keyspace is impossibl...

Yet another thread where you go off the deep end and have no clue what you're talking about. Mask attack in hashcat is not random, it's quite the opposite. It uses probabilistic Markov ordering to ...

Ok I did some digging into this one and was able to figure out what you've got. My initial assumption was that the salt was null and that what you had was equivalent to "$6$rounds=5000$$", which assu...

You'll need hashcat-legacy but even then your CPU might be way too old.

Office 2007 is very slow. Four GPUs likely won't get you very far, especially if you have a lot of documents.

Correct. Legacy Hashstack is tied to upstart plus some other things specific to Ubuntu 14.04. Hashstack Pro will officially ship on 16.04.

Don't forget writing to potfile, rewriting hashlist when using --remove, etc. can all present a bottleneck when using a storage device with low throughput.

This looks more like an Ethereum mining rig than a Hashcat rig. The RX480 is a shitty GPU for password cracking, and if you have 48GB VRAM (6x8GB) then you really want at least 48GB of host RAM as wel...
