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.

Access control technology for peer-to-peer sharing

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 encryption key from a second user device via a peer-to-peer connection; transmitting, by the first user device, the wrapped encryption 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 an encryption key derived from the wrapped encryption key; and decrypting the encrypted media item using the encryption key to play the media item.

Systems and methods include receiving an indication of a hardware or software configuration of a client device. Content associated with a downloadable application is identified by matching installation requirements for the application to the hardware or software configuration of the device.
