Epic cracking!

...then even a 20 char long hash can be cracked within minutes,but nobody is interested, what to do?

Let me brake that down for you. Let's assume a 20-char hash of lower/upper/numbers. 62^20=7*10^35 combinations.
You want to crack that in 1 hour, than there must be ~2*10^32 tries every second.
A GTX1080Ti makes 4.6*10^10 hashes/s in MD5.

So you would need ~4 sextillion GPUs to do the job in one hour.

Strength in unity is what I wanted to convey,cracking a WPA hash in seconds would be far,far better than spending 2 or 3 hours to crack it on a stand-alone computer.
