Multibit Classic setup?
How can i use hashcat with a multibit classic hash? 

I have used JTR that has a native multibit support but want to utilize hashcat combinator attack instead.

What do you mean with multibit support? If you're talking about encoding, hashcat has iconv support since v3.6.0
Sorry, let me refrase since i made it a bit unclear.

I want to crack a Multibit Classic hash with hashcat, how do i write the command to specify the hash type for hashcats process?
This algorithm is not supported atm
