Hey,

I have just enabled End-to-End-Encryption and fiddled around with the Google Drive Backups.
They now store crypt15 instead of crypt14 files.
Can you please implement a method to decrypt those with the 64-digit End-to-End-Encryption Key?

If there is any information on how the encryption works or the actual decryption key is generated, I might create a patch myself.
However, I for now wasn't able to figure out how to use the 64-digit key.

Maybe WhatsApp does a nested encryption here as well?

Cheers,
Mark
