No, that’s not correct. I mean, it is, technically, but it is not the best way to solve WIF problem. You know that you look for a private keys with a given stride, which is “58^number of known characters to the end”, in your case 58^15.
Thank you very much , i will try to prepare the necessary configurations and will try to solve it .
can the ckeys in the wallet.dat files cracked through the master key , i saw something like this before but i can't remember what it was .
