Remarks

All content keys have a key identifier put into the header of the content which identifies what key was used to encrypt that content. The key identifier can also be used with a key seed value to generate the content key. This method of key generation means that the service does not have to store a large database of content keys. However, content keys can be generated using any cryptographically sound manner.
