Usage

Prerequisites

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/"

Decryption

./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 .schema
