In EPUB, encrypted content is declared in encryption.xml with the following information (as of EPUB 3.1):

  • algorithm used to encrypt the resource
  • how the resource is stored in the ZIP container (Store or deflate)
  • original size of the resource

In addition to these information, other relevant info are missing:

  • identifier for a specific DRM scheme
  • profile for a specific DRM (very useful for LCP)

In this new manifest, using the Properties Object could be a good fit to provide that info.
