Advanced malware sometimes injects fake wallets or alters the KDF parameters. By extracting the hash and comparing the iteration counts/salt against known good standards, you can detect tampering.

This will output the SHA-256 hash of the wallet.dat file.

There are three primary scenarios where extracting the hash becomes essential:
