After executing the attempt of WhatsApp decrypting database method, I got the error message as described below:
Traceback (most recent call last):

Exception: Invalid CBC padding
Doing my troubleshooting research, I guess this error is related to the decryption process of whatsapp chatstorage.sqlite. I have successfully installed all dependencies except the fastpbkdf2, but as described in the readme file, it is optional to the code works.
I follow whatsapp development, and they have improved their encryption or security solutions yearly, unlike iTunes which doesn't change very often. Does this CBC padding error have a possible solution?
Also, can you please show a code example of how to decrypt Manifest.db?
Thank you for the interesting project!
