Four Way Handshake. How many ways ?

[henke1k]

Hello guys, how many ways is necessary of the 4-way handshake to be able brute-force it ?

I made a research and some guys tells that 2 ways (1,2 ) is enought, but other guys tells that at least 3 ways of 4.

Could you tell me how many ways is necessary for Hashcat-plus
and the Max lenght password can i do with it ?

Thanks Dudes.
