    Thread: Cracking foreign words/characters
Post: RE: Cracking foreign words/characters

It's often better to encode the custom charsets in the mask file itself, because it's persistent documentation of the nature of the attack that lives beyond that particular commandline.

Yes, especially with fast hashes like MD5, a slow Internet connection definitely makes a difference. I speak from Alaskan experience. :) You might switch to only using --brain-client-features=2, so...

On the (Windows?) command line, you'll need to handle differently any strings that contain an apostrophe ('). One of these may work: 1. Double quotes around the entire mask: Code: -- hashcat...

Post: RE: Passwords

Being self-taught can be rewarding. With just a little bit of reading (hashcat FAQ, some examples/demos on YouTube), you can get the basics down pretty quickly.

Yes, UTF8 is probably fine for WPA2 entered via a web interface. It sounds like you have the rest of the basics covered. Good luck!

Post: RE: bcrypt $2*$, Blowfish (Unix) slow speed

What value is in the "cost" field of your hash? (the second $-separated field, two digits wide)? Based on the speed you're getting, I'm guessing that it's probably cost 10? If so, that speed is norma...

Post: RE: bcrypt $2*$, Blowfish (Unix) slow speed

(Unless you also post the plaintext, please don't post hashes.) Your performance is quite normal for cost 10 on a 1080.

Yeah, I see the Layer-8 use case. You need to be able to assure people that you're not cracking passwords that are 15 chars or longer. There's no way I know of within hashcat itself to guarantee that...

Hmm, I wonder how hard it would be to modify hashcat to use -O to reject longer than 14 instead of 15.

You can use whatever rules make sense for your target. You may have to experiment with --stdout to determine whether the combination of --case-permute and your rules are doing what you're expecting.
