The original proof of concept uses the built-in password-based encryption provided by iTunes. An open question is whether this should be supported long-term. Some concerns:

  • Relies on password strength. This could be an issue, especially if users choose to store their backup in the public IPFS network
  • There are some manifest/metadata files that don't seem to be encrypted. How sensitive is this data?

Possible ideas:

  • Custom encryption mechanism that requires a more strict key-management integration and encrypts manifests
  • Use the built-in encryption, but enforce a password strength
  • Leave it up to the user

More info on the metadata:

There is definitely sensitive data.
