Widevine Master License Agreement

You can create an empty message with no values, just “{}”. A license template with default values is then created. The default setting works in most cases. Microsoft licensing scenarios should always use the default settings. If you need to set the provider values and content_id, a provider must match the Widevine credentials. Hello nice to meet you, I`m Derrick in Korea. I have a simple question, I want to create encrypted content with Google Widevine Drm with edash-packager and then I hope to play with Sharka player and my local Android test player with encrypted content (test). After reading the README document, it appears to require a registration process with the Google license server. After converting the RSA signing key to.

How do I register my Signingkey with the Google License Server? The Content Decryption Module (CDM) is installed on the device of each user who reads the encrypted content widely. There is a unique module for each type of device. The CDM creates an encrypted license request and sends it to the Widevine license server. The Widevine license server responds to the player`s request and sends encrypted content with the license information. The drive transmits the encrypted content to CDM, which then passes it to the OEMCrypto module for decryption. The encrypted content is then decrypted with the digital content playback license. When a user purchases digital content (para. B a song) in the Windows Store, a key is created for the purchased content. The audio file is protected by Advanced Audio Content Coding (AAC) technology, which encodes files at medium to high bit rates. It is designed to provide better sound quality than MP3. An audio layer with a master key is used that uses the AES algorithm.

The master key is also stored in the protected audio file. Output Protection: PlayReady can apply playback restriction to output ports on playback devices based on licensing policies. If an existing policy exists, you do not need to specify the values in the content key specification. The existing policy associated with this content is used to determine output protection, such as . B protection of high-bandwidth digital content (HDCP) and the General Copy Management System (CGMS). If an existing policy is not registered with the Widevine license server, the content provider can include the values in the license request. requestProperties – Contains additional headers to include in the outbound license request. A valid box is available for a short period of time (between creating the DRM instance and loading the keys). MediaDrmCallback callback executeKeyRequest() can use it to customize license key retrieval.

The master key is encrypted with the user key held by iTunes and also sent to the Apple server. In 2019, a developer attempted to bundle Widevine into an Electron/Chromium-based app for video playback and received no response from Google after requesting a licensing agreement, blocking the use of DRM in the project. [18] [19] Later, he received the answer: A Widevine license application is formatted as a JSON message. iTunes keeps a collection of user keys for all songs purchased in its library. There is no need to connect to a server for a user key. To play a protected song, iTunes matches the created user key with its collection of user keys to decrypt the master key. .
