Support .mcrypt1 files #20

Open ElDavoo opened 2 years ago

This will probably be complicated and result in a writing of a google drive downloader, as metadata needs to be decrypted and it will probably a lot of stuff and logic to write.

.mcrypt1 files are encrypted media files uploaded in the cloud (google drive) while using E2E encrypted backups.

I can't allocate time to this task, so for a few months there will be no progress. I'll be happy to accept external contributions. There should be no forward secrecy, so you might be able to start downloading encrypted media using existing downloaders and decrypt them when the tool will be ready.

Metadata decryption function added

hello @ElDavoo,

can you confirm if there is a way to decrypt .mcrypt1 files?

I've overwritten my drive backup by mistake but I have all my photos/videos .mcrypt1 files locally in the phone, so I would like to restore them.

Regards,

Sorry, but .mcrypt1 by themselves are not decryptable. Additional metadata from Google drive is needed.

The latest version on master branch of whapa downloads this metadata in the form of .mcrypt1-metadata files.
