Idk. I found this from someone who claims to have cracked..

Tripcode: ITPb.qbhqo -> Password: Matlock Tripcode: UW.yye1fxo -> Password: M@tlock! Tripcode: xowAT4Z3VQ -> Password: Freed@m- Tripcode: 2jsTvXXmXs -> Password: F!ghtF!g Tripcode: 4pRcUA0lBE -> Password: NowC@mes Tripcode: CbboFOtcZs -> Password: StoRMkiL Tripcode: A6yxsPKia. -> Password: WeAReQ@Q

also found this:

"Ron Watkins implemented the "secure tripcode" system on 8chan. The secure system can be differentiated from the old system by the preceding "!!" at the beginning. The old system can be cracked trivially. No such crack exists for the new system."
