Awesome - that's *perfect*! That's exactly what I needed to know.

Post: RE: truncating passwords instead of rejecting them

Hmm, still rejecting 60% of my passwords. I dug around a little more, and found this thread: https://hashcat.net/forum/thread-3132.html It turns out that on GPU, using -r to specify a separate t...

    Thread: Weird exception when cracking DES(unix)
Post: RE: Weird exception when cracking DES(unix)

Does hashed_file.txt contain only hashes -- no usernames, etc.? Does it work OK with other masks?

Using --loopback might be helpful.  Have you been through some common masks (Korelogic pathwell, and the ones that come with hashcat) and rulesets (d3ad0n3, etc.) ?   Have you looked at PRINCE...

    Thread: Which Graphic Card is better
Post: RE: Which Graphic Card is better

The 670 is based on the Kepler architecture. The 750 Ti is based on Maxwell. The Maxwell architecture is much better for hashcat. Even just one 750 Ti would be better than a 670. And 2 750s would be e...

Post: RE: mask help

You'll need to be realistic about your odds.  You can improve them a bit, but it will take some work. Office 2013 hashes are extremely slow. On my GTX 970, I only get about 4000 hashes per second ...

Post: RE: mask help

When incrementing, your mask needs to be as long as your increment maximum, so your syntax needs to be adjusted accordingly: ?d?l?l?l?l?l?l?l And yes, anything you can do to narrow it down will ...

Interesting. I'm not familiar with a way to divide up hashcat's resources in this way. The only workaround that I know of would be to use --session and --restore for each of the three instances, and...

Guessing wildly based on the specs, I would expect it to be a bit slower than a 1080 - and the list price is about what used 1080 FEs are going for, so it may be a bit of a wash. A full benchmark w...
