Represents Digital Rights Management (DRM) information that is stored in an EncryptedPackageEnvelope.
Assembly: WindowsBase (in WindowsBase.dll)
RightsManagementInformation provides access to the PublishLicense and UseLicense data stored in a rights managed protected Package.
The following example shows how to initialize a RightsManagementInformation object for encryption. For the full sample, see Rights Managed Package Publish Sample.
WriteStatus(" Signing the UnsignedPublishLicense\n" + " to build the PublishLicense."); UseLicense authorsUseLicense; PublishLicense publishLicense = unsignedLicense.Sign(_secureEnv, out authorsUseLicense); WriteStatus(" Binding the author's UseLicense and"); WriteStatus(" obtaining the CryptoProvider."); CryptoProvider cryptoProvider = authorsUseLicense.Bind(_secureEnv); WriteStatus(" Creating the EncryptedPackage."); Stream packageStream = File.OpenRead(packageFile); EncryptedPackageEnvelope ePackage = EncryptedPackageEnvelope.CreateFromPackage(encryptedFile, packageStream, publishLicense, cryptoProvider); WriteStatus(" Adding an author's UseLicense."); RightsManagementInformation rmi = ePackage.RightsManagementInformation; rmi.SaveUseLicense(author, authorsUseLicense); ePackage.Close(); WriteStatus(" Done - Package encryption complete."); WriteStatus("Verifying package encryption."); if (EncryptedPackageEnvelope.IsEncryptedPackageEnvelope(encryptedFile)) { WriteStatus(" Confirmed - '" + encryptedFilename + "' is encrypted."); } else { MessageBox.Show("ERROR: '" + encryptedFilename + "' is NOT ENCRYPTED.", "Encryption Error", MessageBoxButton.OK, MessageBoxImage.Error); WriteStatus("ERROR: '" + encryptedFilename + "' is NOT ENCRYPTED.\n"); return false; }
The following example shows how to initialize a RightsManagementInformation object for decryption. For the full sample, see Rights Managed Package Viewer Sample.
