PublishLicense (Clase)
Ensamblado: WindowsBase (en windowsbase.dll)
PublishLicense defines security data about rights, users, and other security-related information. The license defines how a specific user on a specific computer can use specified rights managed content.
The publishing process begins with the document author, who defines rights information in an UnsignedPublishLicense. Next, the author creates a signed PublishLicense by calling the Sign method of the UnsignedPublishLicense. The serialized form of the signed PublishLicense can then be provided to end users who can use it to acquire a UseLicense by calling the AcquireUseLicense method of the PublishLicense. The returned UseLicense then allows the client application to exercise the rights that were granted to the user.
As with other System.Security.RightsManagement types, PublishLicense is only usable in full trust applications.
The following example shows how to initialize a PublishLicense by using the Sign method.
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; }
