[FEATURE] E2E encrypted iCloud backup support

[FiloSottile]

If an iOS client enables end-to-end encrypted backups, the chats are not stored in device backups anymore, but only in iCloud.

From a Mac it's very convenient to access the encrypted iCloud backup at

/Users/filippo/Library/Mobile Documents/57T9237FN3~net~whatsapp~WhatsApp/Accounts/XXXXXXXXXXXXX/backup/ChatStorage.sqlite.enc

I imagine this can be decrypted with the 64 character E2E key. It would be nice to add support to WhatsApp-Chat-Exporter.

You mean iCloud Advanced Data Protection or the WhatsApp built-in E2E encryption?

[FiloSottile]

ADP is transparent from a macOS client. ChatStorage.sqlite.enc is encrypted by WhatsApp's built-in E2E encryption.

Thanks! Will look into it when I have access to Mac.

I'd love this as well!

@FiloSottile, did you find some solution here? And how can you find the WhatsApp encryption key to use to read this file?
