Abstract
A method for wrapped keys with access control predicates includes obtaining a cryptographic key for content. The method also includes encrypting the content using the cryptographic key and generating an encryption request. The encryption request requests that a third party cryptography service encrypts an encapsulation of the cryptographic key and an access control condition governing access to the content. The method also includes communicating the encryption request to the third party cryptography service. The encryption request includes the cryptographic key.
