I have a wallet.dat and a .txt file inside this txt file wallet number like : L1aC2... and a hash like: $bitcoin$64$a2z...

How can I reach to my fund inside this wallet ? I kinda have some memory about password, but I don't exactly remember.

  • Make a backup first, before you try anything else. Do you remember what software you used? What have you tried so far?

The text beginning with "L1aC2" could potentially be a private key for a wallet. You have the option to import it into another Bitcoin Core wallet or Electrum to check the balance.

Instructions for importing a single private key into Electrum can be found here.

As for the hash, it is a Bitcoin Core wallet hash. Tools such as John the Ripper or Hashcat can be used to bruteforce the password.

  • I wish it was private key but unfortunately I figured out its just my public key, other one is my passphrase which is encrypted, I tried a lot of wordlists and even created a lot of combinations which ending with dates (1 TB wordlist) still no result( freak*n satoshi, while trying to make it so secure, he missed human error factor. It would be great to put smth like "I forgot my password" :)
