Brute force a wallet.dat with a partially known password

[Alicatraz]

Hi , as the title says it , the password consists of 11 characters 7 known and 5 unknown ( positions of unknown characters are not 100% known )
the password also has two special characters one known and one unknown ( mistyped most likely )
what is the best tool to brute force the file ?
I appreciate your help .

Hi , as the title says it , the password consists of 11 characters 7 known and 5 unknown ( positions of unknown characters are not 100% known )

When you say "the position of unknown characters are not 100% known"... do you mean that some are known and some aren't? or that their positions are completely unknown?

the password also has two special characters one known and one unknown ( mistyped most likely )

Are these 2 special characters included in the 11 characters? or are they in addition to them?


In either case, I would tend to concur with ETFbitcoin that btcrecover is a very good option. It gives you quite a lot of flexibility in defining the "structure" of a password, and how to construct password candidates from wildcards etc.
