PREREQUISITES:

1. O/S: Windows Vista, Windows 7, Windows 8, Windows 10, Mac OS X or Linux
2. Java - If not installed: https://www.java.com/en/download/
3. ADB (Android Debug Bridge) Drivers
4. USB Debugging must be enabled on the target device. Settings -> Developer Options -> (Debugging) USB debugging
   If you cannot find Developer Options then please go to: Settings -> About phone/device and tap the Build number
   multiple times until you're finally declared a developer.
5. Android device with Android 4.0 or higher. I.E. Ice Cream Sandwich, Jelly Bean, KitKat, Lollipop, Marshmallow or Nougat.

INSTRUCTIONS:

1. Extract "WhatsApp-Key-DB-Extractor-master.zip" maintaining the directory structure.
2. Click on "WhatsAppKeyDBExtract.bat" (Windows) or "WhatsAppKeyDBExtract.sh" (Mac OS X / Linux).
3. Connect your device via USB, unlock your screen and wait for "Full backup" to appear.
4. Enter your backup password or leave blank (if none set) and tap on "Back up my data".
5. Confirm backup password in your command console and then check your "extracted" folder.

TROUBLESHOOTING:

1. If you have never used USB Debugging before, you may also need to verify the fingerprint.
2. If you have set a default backup password in your Android settings, then this MUST be the
   backup password that you PROVIDE when prompted to backup your data. Else it WILL fail!
3. Linux and Mac OS X users may need to set the script permissions as executable. Depending on the
   adb permissions, you may also need to "sudo ./WhatsAppKeyDBExtract.sh" from your command console.
4. If you're having issues with "WhatsAppKeyDBExtract.bat" then right click "WhatsAppKeyDBExtract.ps1"
   and select "Run with PowerShell". You may have to enter "y" at first run for execution policy.
5. If you get an error saying "AES encryption not allowed" then you need to update your Oracle Java
   Cryptography Extension (JCE) to Unlimited Strength Jurisdiction Policy Files.
