Is there any tool to brute force/run password lists against wallet.dats?
I have one around that I am adding coins to but just can't remember my own password.
More likely you have obtained someone elses wallet.dat file that they have encrypted and they do not know you have a copy of this wallet.dat so they are still using it, and you do not know their key but would quite like to access their coins.
send any new coins to a new address, sure you may remember the password but hedge against that possibility with another wallet, please. for my sake, for my sanity, do it for me.
It would be pretty unfeasible to attempt a brute-force, due to the number of encryption rounds.
