well i dont get your point, you wrote:
when you already know the pass aka password and salt you already have your password???
when you are talking about hash:salt, put hash:salt into a file (input) and run hashcat like
hashcat -a0 -m1710 input dictionary-file
OR
hashcat -a3 -m1710 input bruteforce-mask
please see the dokumentation https://hashcat.net/wiki/doku.php?id=hashcat and given examples
