云医院(HIS)FHIR数据如何加解密
公钥加密，私钥解密
public static void EncryptXml(ref XmlDocument xmlDoc, string targetElementName, string ThumbPrint)
{
try
{
//XML有效性验证
//XmlElement targetElement = Doc.GetElementsByTagName(targetElementName)[0] as XmlElement;
XmlNodeList targetElements = xmlDoc.GetElementsByTagName(targetElementName);
if (targetElements == null || targetElements.Count==0)
{
throw new CryptographicException("待加密节点[" + targetElementName+"]不存在");
}
if (targetElements.Count >1)
{
throw new CryptographicException("待加密节点[" + targetElementName + "]数量超过一个了！");
}
XmlElement targetElement = targetElements[0] as XmlElement ;
//获取加密证书
X509Certificate2 Certificate = Wdpc.Security.Certificate.Store.GetX509Certificate2FromStore(ThumbPrint);
EncryptedXml eXml = new EncryptedXml();
//加密
EncryptedData encryptElement = eXml.Encrypt(targetElement, Certificate);
//替换加密节点
EncryptedXml.ReplaceElement(targetElement, encryptElement, false);
}
catch (Exception ex)
{
throw new Exception("Wdpc.Security.Certificate.EncryptionAndDecryption.EncryptXml" + ex.Message.ToString());
}
}
public static void DecryptXml(ref XmlDocument xmlDoc, string ThumbPrint)

try

//获取加密证书
X509Certificate2 Certificate = Wdpc.Security.Certificate.Store.GetX509Certificate2FromStore(ThumbPrint);
EncryptedXml exml = new EncryptedXml(xmlDoc);
//设置密钥-名称映射，可以随意设置一个名称，我们使用证书私钥解密
exml.AddKeyNameMapping("rsaKey", Certificate.PrivateKey);
//解密
//此时会寻找所有<EncryptedData>，查看<KeyInfo>节点，解密<CipherData>节点。用解密<CipherData>的结果来替换<EncryptedData>元素。
exml.DecryptDocument();
}
