    Thread: How to change password length (min/max)
Post: RE: How to change password length (min/max)

Short answer: add the '-O' flag. The default min and max lengths shown are very broad, and not as specific as any particular attack (though they do have broad impact on attack speed). It's about yo...

Scripting. There's no canned way to do this. You could group your other data into an overloaded username field, and then use --username.

Discussion of speed needs to know what type of hash is the target. Either: A) your attack is malformed (can you post your syntax, omitting any real hashes?), or b) it's a pretty fast hash and y...

You're describing an online attack. Hashcat only works for offline attacks (with the hash in hand).

Most basic use of crunch can be executed by hashcat directly. The ?H charset is cap hex (0-9 and capital A-F). If it's a randomly generated string within that charset, a mask of ?H?H?H?H?H?H?H?H?H?...

Like this, but adapted to your hash type (-m), hash, and mask (the ?H sequence). Code: -- $ hashcat --help | grep Brute-Force Brute-Force | MD5 | hashcat -a 3 -m 0 example0.hash ?a?a?a?a...

hashcat no longer has a dependency on CUDA - only on OpenCL. See also: https://hashcat.net/wiki/doku.php?id=frequently_asked_questions#why_does_hashcat_not_work_with_my_kali_operating_system

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...

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