Lost passphrase, help with syntax!

[p72mad]

I am trying to use Hashcat to crack a personal Bitcoin wallet with a lost passphrase. The wallet was created on WarpWallet, which uses the XOR'd output of scrypt and PBFDK2, with a salt and passphrase, to generate a key pair. I do remember the salt, and the relatively short length of my original passphrase. I also know the wallet address. Basically, I want to try to brute force all combinations within my known character set using the known salt until I find one that matches the known public key.

Having trouble with the parameters/setup for this. I have hashcat running nicely but could use some assistance with syntax.

Thanks all.
