Exporting and decrypting your Whatsapp message SQLite store (Android)

Create an E2E encrypted backup on Whatsapp Settings on your phone. It will prompt you to setup E2E encryption either with a custom password or an autogenerated 64 bit string. Choose the 64 bit option and save this string!

Create a Python virtualenv and install wa-crypt-tools

 pip install wa-crypt-tools

Create the key file

 wacreatekey --hex <your-hex-value>
 # creates a file called encrypted_backup.key

Connect your phone and pull the encrypted DB file

 adb pull /sdcard/Android/media/com.whatsapp/WhatsApp/Databases/msgstore.db.crypt15
 # will copy this file to your cwd

Decrypt the DB file using your key

 wadecrypt encrypted_backup.key msgstore.db.crypt15 msgstore.db
 # key15.py:54     : [I] Crypt15 / Raw key loaded
 # wadecrypt.py:271     : [I] Done
