云医院(HIS)Fhir数据如何完成签名认证

私钥签名,公钥验证 

 public static void SignXmlDoc(ref XmlDocument xmlDoc, string ThumbPrint,bool AddKeyInfo)
        {
            SignedXml signedXml = new SignedXml(xmlDoc);

            //获取签名证书
            X509Certificate2 Certificate = Wdpc.Security.Certificate.Store.GetX509Certificate2FromStore( ThumbPrint);
            signedXml.SigningKey = Certificate.PrivateKey;

            //引用
            //指定了在哈希运算之前应当如何对将要签名的数据进行处理。
            //URI属性标识要签名的数据,而Transforms元素指定如何处理数据。
            Reference reference = new Reference();
            reference.Uri = ""; //空字符串,它指定对整个文档进行签名并且包含签名,需要特别注意的是文档中如果已经存在<Signature>节点,在签名前将先被移除。
            XmlDsigEnvelopedSignatureTransform env = new XmlDsigEnvelopedSignatureTransform();  //使用包封式签名转换
            reference.AddTransform(env);
            signedXml.AddReference(reference);

            //向签名的接收方提供签名证书的信息,在验证签名的同时可以验证签名证书
            if (AddKeyInfo)
            {
                KeyInfoX509Data keyInfoX509 = new KeyInfoX509Data(Certificate, X509IncludeOption.EndCertOnly);
                signedXml.KeyInfo.AddClause(keyInfoX509);
            }
         

            //签名
            signedXml.ComputeSignature();

            //将签名加入XML中
            XmlElement xmlDigitalSignature = signedXml.GetXml();
            xmlDoc.DocumentElement.AppendChild(xmlDoc.ImportNode(xmlDigitalSignature, true));
        }

        public static Boolean VerifySignXmlDoc(XmlDocument xmlDoc, string ThumbPrint)
        {
            //XML有效性验证
            XmlNodeList nodeList = xmlDoc.GetElementsByTagName("Signature");
            if (nodeList.Count <= 0)
            {
                throw new CryptographicException("缺失signature节点");
            }
            if (nodeList.Count >= 2)

            }

            SignedXml signedXml = new SignedXml(xmlDoc);

            //验证签名以及证书,verifySignatureOnly设置为flase则不验证证书
            return signedXml.CheckSignature(Certificate, true);
