Abstract: Implementations disclose an access control mechanism for peer-to-peer sharing technology. A method includes receiving, by a processing device of a first user device, an encrypted media item and a wrapped key from a second user device, wherein the wrapped key comprises content masked from the first user device; transmitting, by the first user device, the wrapped key and a request to a media server to determine whether the first user device is authorized to play the encrypted media item; receiving, from the media server, a response indicating the first user device is authorized to play the encrypted media item, the response comprising a cryptographic key derived from the wrapped key; and decrypting the encrypted media item using the cryptographic key.
