Abstract
Techniques and mechanisms described herein facilitate the management of digital rights for media content item presentation. According to various embodiments, a request for a content decryption key may be received at a media application implemented at a computing device. The request may be transmitted by a media content player implemented at the computing device. The request may be transmitted in accordance with a designated key exchange protocol. A license for an encrypted media content item corresponding with the requested content decryption key may be identified at the media application. Based on information included in the license, encrypted key material may be decrypted to create the requested content decryption key via a processor at the computing device. The requested content decryption key may be provided to the media content player.
