A file may contain an unencrypted and an encrypted portion. The unencrypted portion may contain a layout section that may point to a published license, metadata, and a contents section, where the contents section is in the encrypted portion. The encrypted portion may contain the contents section which may act as a directory for one or more included files that may be compressed and stored in the encrypted portion. When the file is opened by a receiver, the receiver may read the published license and communicate with a security server to establish access rights and receive at least one key for decrypting at least a portion of the encrypted portion of the file. The receiver may then gain access to the included files.
