Brute Force minecraft account password cracker

I need a good brute force password cracker that i can use for a minecraft account. im trying to get into the owner of the server i play on account. hes a greedy asshole. if you bring up that his server is pay to win then he deletes all the messages and if u do it twice he blocks you. i really want revenge and to ruin his server please help.

Have you tried JTR software? (I know it's mostly used for decrypted files, but it's worth a shot)
