Excel Protected Workbook Known PW Length

[HelmanFrow]

geezus man, you're pretty impatient.

😂 Guilty as charged, although I'm also tenacious + curious and I have a habit of using threads I've started to keep track of my progress.

Your first attempt at cracking your password would have been fine if you didn't keep installing drivers on top of drivers. Just use the damn OpenCL driver that would have worked at square one.

Whoops.
In my defense, despite my best efforts I still lack perfect information in every knowledge domain so I may occasionally not realize there is an OpenCL driver.

Look at the Wiki for your hash.

Now look at how your attack will work.

Yup, I pored over those pagers for hours.
Like I said, I'm a little slow on the uptake.

So you have your hashmode and your attack mode so now you just need to put it all together.

hashcat.exe -d 2 -m xxxxx -a 3 -1 ?l?u hash.txt ?1?1?1?1

Aha. Now I understand the syntax a little better.

Anyway, that gets me down to one error code instead of three:

Code:

PS D:\desktop\hashcat-6.2.5> ./hashcat.exe -d 2 -m9600 -a 3 -1 ?l?u hash.txt ?1?1?1?1

Any ideas?
