Abstract: Embodiments are directed towards decrypting encrypted content. A key for decrypting the encrypted content may be provided to a web application executing within a browser. The application may employ a generic cryptography application program interface (GCAPI) to perform actions on the key, including, storing the key, decrypting an encrypted key, generating another key, converting the key to a different encryption type, or the like. The GCAPI may or may not be enabled to explicitly share the key with the browser's media engine. In response to receiving encrypted content, the GCAPI may provide the key to the application, explicitly or inexplicitly to the browser's media engine, or the like. The key may be utilized by the application, the browser, the media element, browser's media engine, and/or the GCAPI to decrypt the encrypted content. The decrypted content may be displayed within the browser to a user of a client device.

Abstract: A method, apparatus, and manufacture for content protection for protecting some objects is provided. A content protection operation or license operation is performed for at least one media object of a web application. Some or all of the objects are then marked as protected. When an operation is performed that accesses a protected object, a user agent determines whether to deny the operation, to allow the operation and mark data exported by the operation and objects storing the exported data as protected objects, or to allow the operation and not mark data exported by the operation and objects storing the exported data as protected objects.

Abstract translation: 实施例针对解密加密的内容。 用于解密加密内容的密钥可以被提供给在浏览器内执行的web应用。 应用程序可以使用通用密码应用程序接口（GCAPI）来对密钥执行动作，包括存储密钥，解密加密密钥，生成另一个密钥，将密钥转换成不同的加密类型等。 GCAPI可能会被启用，也可能不会被显示与浏览器的媒体引擎共享密钥。 响应于接收加密的内容，GCAPI可以向应用程序提供密钥，明确地或不明确地向浏览器的媒体引擎等提供密钥。 应用程序，浏览器，媒体元素，浏览器的媒体引擎和/或GCAPI可以使用密钥来解密加密的内容。 解密的内容可以在浏览器内显示给客户端设备的用户。
