Decode Py

The document is a Python script that performs a brute-force attack to decrypt a BIP-38 encrypted Bitcoin private key using a generated passphrase. It checks if the decrypted private key corresponds to a specified target Bitcoin address. The script utilizes libraries for cryptographic functions and includes a delay to manage the brute-force attempts.
