Represents the key used to encrypt PlayReady content with an AES algorithm.
public class AESContentKey : Microsoft.Media.Drm.ContentKey
type AESContentKey = class

Public Class AESContentKey
Inherits ContentKey
- Inheritance
Remarks
All content keys have a key identifier put into the header of the content which identifies what key was used to encrypt that content. The key identifier can also be used with a key seed value to generate the content key. This method of key generation means that the service does not have to store a large database of content keys. However, content keys can be generated using any cryptographically sound manner.
Constructors
AESContentKey(Byte[], Guid, ContentKeyType) |
Initializes a new instance of the AESContentKey class with the specified ContentKeyType. The content key is specified by the caller. |
AESContentKey(Byte[], Guid) |
Initializes a new instance of the AESContentKey class with AES128BitCTR mode. The content key is specified by the caller. |
AESContentKey(Guid, Byte[], ContentKeyType) |
Initializes a new instance of the AESContentKey class with the specified ContentKeyType. The content key is auto-generated by the SDK using a key seed. |
AESContentKey(Guid, Byte[]) |
Initializes a new instance of the AESContentKey class with AES128BitCTR mode. The content key is auto-generated by the SDK using a key seed. |
