User seeks to restore the private key to the 2019 Daedalus wallet

The user wrote on Reddit that he had created a Daedalus wallet between 2019 and 2020, but had lost the crosswords and expenditure codes for years. Nevertheless, he kept and backed up the entire Daedalus application catalogue at the time, including the secret.key and database files. Now, he hopes that the community or developer will provide any tools, restore scripts or methods to decrypt or extract the private key from the Byron-era secret.key document, or whether the expenditure password can be broken violently through encrypted documents. He asked whether anyone had succeeded in recovering funds from similar legacy structures or whether any known open-source tools were available。
