Hi all. I was wondering how iOS handles Contacts images, when it comes to encryption. It would be simpler without ADP (Advanced Data Protection), but I have it enabled.
ADP end-to-end encrypts your images, but contacts still uses the legacy (less private) encryption methods. So what happens with the photo tied to the Contact? Is it encrypted, or not? I’d assume as it’s Contact data, it gets treated as part of everything else the Contact holds. I’d just like to know for certain, hence this post. Bonus points if you can provide a source.
This Name and Photo Sharing feature is proprietary and does not have anything to do with CardDAV directly. I think if you sync your Contacts in your iCloud (with ADP enabled), your Contact info is still unencrypted.
