Decrypt Bitcoin Wallet Backups (from what is known as Schildbach Wallet)

Bitcoin Wallet Decrypt (BackupFile -> Mnemonic)

If you have been using the Bitcoin Wallet from Bitcoin Wallet developers, it is likely you want to get your Bitcoin Cash or take control of your private keys.

I wrote this script to simplify this process for myself. This script will obtain a BIP-39 mnemonic that can later be used to transfer Bitcoin or Bitcoin Cash to other wallets.

WARNING: You will be decrypting your wallet so the private key (mnemonic) might be compromised.

Instructions

In your mobile:

• Go to Safety and remove the spending PIN.
• Backup your wallet. Remember the password you use.
• Connect your phone with a usb cable and copy the backup file to your computer.

In your computer

Install dependencies

pip install pycrypto protobuf

Run the script (replace with the appropriate FILENAME(backup file) and PASSWORD(your backup password))

wallet-decrypt.py FILENAME PASSWORD

You will get a mnemonic and derivation path that can be used in Electrum / Electrum Cash.
