Exempel

I följande exempel visas hur du använder den här metoden för att initiera en CryptoProvider.

WriteStatus("   Signing the UnsignedPublishLicense\n" +
            "       to build the PublishLicense.");

WriteStatus("       obtaining the CryptoProvider.");
CryptoProvider cryptoProvider = authorsUseLicense.Bind(_secureEnv);

WriteStatus("   Creating the EncryptedPackage.");
