  • if i understand it correct: do you have 1 p2sh address and with the 1 privkey recovered you can access all of the funds?

  • a bitcoin private key is in base58 format (right?), so for bruteforcing 4 characters you need to check 11316496 (11.3 million) private keys... (can take a while)

  • maybe your coins are already gone. if one of the tools you tried had evil thoughts about your private key there is no way to get them back

  • a private key has checksum bytes, right? the last 4 characters can be made using the 256 bit priv key
