New Attack-Mode: Association Attack

[royce]

Code:

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

This doesn't seem to me to be the same thing? I'm suggesting warning on when the number of *hashes* is too small, not the number of wordlists words. If the minimum threshold is a known number, as you said here:

Your hashlist needs a large number of unique salts to make this attack efficient (to utilize the GPU fully). Ideally the number of GPU Processors * 64 (or more). You can find out about the GPU Processors of your GPU using hashcat -I. My GTX980 has 16, so I need a hashlist of at least 1024 entries to fully utilize the GPU.

.... then it seems to me that all of these values are known at runtime, and a different warning could be issued.
