Original GitHub issue: https://github.com/ElDavoo/wa-crypt-tools/issues/21

Using the following command:

python ./decrypt14_15.py ./key ./msgstore.db.crypt14 ./msgstore.db

and was greet with the following error message:

File "C:\PyPortable\WhatsApp-Crypt14-Crypt15-Decrypter\proto\C14_cipher_version_pb2.py", line 21, in
_C14_CIPHER_VERSION = DESCRIPTOR.message_types_by_name['C14_cipher_version']
AttributeError: 'NoneType' object has no attribute 'message_types_by_name'

The full details are as follows:

C:\PyPortable\WhatsApp-Crypt14-Crypt15-Decrypter>python ./decrypt14_15.py ./key ./msgstore.db.crypt14 ./msgstore.db

Hmmm, that's interesting.
Which whatsapp version do you have?
It looks like you have some issue with your protobuf library installation, so don't use protobuf parse mode:
What happens when you use -np -v ?

It looks like you have an old version of the protobuf library. As in requirements.txt, check if you have at least version 3.19.4.
From what i've read the program should work with at least protobuf 3.12.

Thanks, ElDavoo, will check on the library, hopefully can get back soon later before end of this month.

I made some experiments, you need at least version 3.19.0 of the protobuf library. I added an exception handler for this case.
