Yes, the file is mine. If it was not mine, how could I know the general wallet address?
You could have just posted any random address; there is no way to prove that it corresponds to one of the private keys in your encrypted
wallet.dat[/t] unless you can decrypt it and sign a message.
Furthermore, we've seen this many times here. People sell encrypted wallet.dat files (sometimes together with some address to 'prove' funds are in the wallet).
Because I don't want to put the encrypted file here, I just put its hash, and whoever can decrypt the hash can find out the password.
Hashes cannot be decrypted. A hash is just that: a hash. A digest. You're asking for people to brute-force a whole
wallet.dat file just from its hash and then it would still be encrypted & they would have to decrypt the wallet file itself.
Task 1 is already impossible and task 2 is pretty tough; combine them (for no reason whatsoever) and you can basically close this thread.
