Abstract
A method, apparatus, and manufacture for a content decryption module (CDM) is provided. A user agent loads a web application. The web application gets a license for encrypted media content. The web application instructs a media stack of the user agent to play the encrypted media content. The license is sent from the web application to the media stack. Next, the license is sent from the media stack to the CDM. The media stack and the CDM are distinct binaries from each other. Encrypted data is sent from the media stack to the CDM. The encrypted data includes at least a portion of the encrypted media content. Next, the CDM provides decrypted data by decrypting the encrypted data.
