CLI tool to extract and decrypt the SQLite database of a backup ZIP of the Sparkasse Android application.
This project was rewritten. In case it does not work for you, you can find the previous version in the branch python-version.
TODO
You need to have a backup zip file. Look at the comments on how to get one. Depending on your Android version, backups are located at:
/storage/emulated/0/ebanking/storage/emulated/0/Android/data/com.starfinanz.smob.android.sfinanzstatus/files
If you are running Android 11 , chances are that you need to access the files using your PC by connecting your phone to the PC via USB. You can also use ADB instead of crappy MTP:
adb pull "/storage/emulated/0/Android/data/com.starfinanz.smob.android.sfinanzstatus/files/"./sparkasse-backup-decrypt --in-file <path-to-backup.zip> --out-file <path-to-target-plaintext.db>
# (you will be asked for your app password)
# Example call:
./sparkasse-backup-decrypt --in-file sfinanzstatus55100Auto20200101-155119.zip --out-file plaintext.db
# You can check if the out file is in plaintext by using sqlite3:
# sqlite3 plaintext.db .schemagit clone https://github.com/nikeee/sparkasse-backup-decrypt.git
cd sparkasse-backup-decrypt
cargo build --release
# binary located at:
# target/release/sparkasse-backup-decrypt
