Enlaza la licencia a un SecureEnvironment determinado.
public:
System::Security::RightsManagement::CryptoProvider ^ Bind(System::Security::RightsManagement::SecureEnvironment ^ secureEnvironment);
public System.Security.RightsManagement.CryptoProvider Bind (System.Security.RightsManagement.SecureEnvironment secureEnvironment);
member this.Bind : System.Security.RightsManagement.SecureEnvironment -> System.Security.RightsManagement.CryptoProvider
Public Function Bind (secureEnvironment As SecureEnvironment) As CryptoProvider
- secureEnvironment
- SecureEnvironment
Entorno al que se va a enlazar la licencia.
Instancia CryptoProvider si el enlace de la licencia se realizó correctamente; en caso contrario, null
.
secureEnvironment
es null
.
En el ejemplo siguiente se muestra cómo usar este método para inicializar un CryptoProvider.
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 +

return false;

Else
