Invalid mask length followed by segmentation fault
#1
Hello all, I am new to hashcat and ran directly into trouble Smile

I am running Debian 11.4
Tried the included 6.1.1 version, the 6.2.5 binary, the 6.2.5 self compiled and git cloned latest.

It also does not matter if use the CPU or the GPU

called with hashcat -a 3 -m 10400 -D 2

hashcat (v6.1.1) starting...

The wordlist or mask that you are using is too small.
This means that hashcat cannot use the full parallel power of your device(s).
Unless you supply more work, your cracking speed will drop.
For tips on supplying more work, see: https://hashcat.net/faq/morework
