            "       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.");
