需要帮助在C＃中创建加密断言

Question

现在我完全坚持如何从我的证书生成Keyinfo并进入SAML Schema类。我的互联网搜索几乎毫无结果。我没有使用任何第三方组件，也无法使用。我需要使用可用的加密.net类直接c＃，没有WIF。我正在尝试使用Assertion Encryption将我的SSO身份提供程序的工作代码库调整为支持断言加密的代码库。有人能指出一些资源来解释如何去做吗？

我需要生成SAML2令牌的以下部分：

            EncryptedKeyType encryptedKey = new EncryptedKeyType();


            X509Certificate2 encryptingCert = null;
            if (findValueSigning.ToString() == findValueEncryption.ToString()) encryptingCert = signingCert;
            else encryptingCert = GetCertBySerialNumber(storeLocation, storeName, findType, findValueEncryption);

            KeyInfo keyInfo = new KeyInfo();
            KeyInfoX509Data keyData = new KeyInfoX509Data(encryptingCert);
            keyInfo.AddClause(keyData);



            //keyInfoRoot.Items = object[] { encryptedKey };
            encryptedData.EncryptionMethod = encryptionMethod;
            encryptedData.KeyInfo = keyInfoRoot;
            encryptedAssertion.EncryptedData = encryptedData;

            response.Items = new EncryptedElementType[] { encryptedAssertion };
