hashing MS Office 2010 so slow

[tea-er]

Dear all,

I am hashing MS Office 2010 excel file and Speed.Dev.#1.....: 1272 H/s.
When I hashing md5 is Speed.Dev.#1.....: 10472.2 kH/s

Is this correct speed of office hashing?
and how to speed up to hashing office document?

GPU is Intel Corporation HD Graphics 530 and commandline is
hashcat --force -a 3 -m 0 xxx.hash ?d?d?d?d?d?d?d?d?d?d?d

Thanks a lot!

Yes, newer Office hashes are pretty slow.

You can add -w 4 and -O; that might help.

Hi Royce,

Now i am use command below,
hashcat --session=123 --force -w 4 -O -a 3 -m 9500 aa.hash ?d?d?d?d?d?d?d?d?d?d

and little bit speed up than before.

Speed.Dev.#1.....: 1432 H/s

Maybe this is the fastest speed on my machine.

Thanks a lot for your help!

You're better off looking for a dedicated GPU and adjusting your keyspace. You're not going to see any significant increase in speeds however, but a 10 digit keyspace is still plausible with the right amount of time.
