XML文件的加密与解密

RijndaelManaged key = new RijndaelManaged();
//设置密钥:key为32位=数字或字母16个=汉字8个
byte[] byteKey = Encoding.Unicode.GetBytes("1111111111111111");
key.Key = byteKey;
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.PreserveWhitespace = true;
xmlDoc.Load(Application.StartupPath + @"\FunctionEnabled.xml");//加载要加密的XML文件
if (key != null)
{
key.Clear();
}
xmlDoc.Save(Application.StartupPath + @"\abc.xml");//生成加密后的XML文件

RijndaelManaged key = new RijndaelManaged();
//设置密钥:key为32位=数字或字母16个=汉字8个
byte[] byteKey = Encoding.Unicode.GetBytes("1111111111111111");
key.Key = byteKey;
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.PreserveWhitespace = true;
xmlDoc.Load(Application.StartupPath + @"\abc.xml");//加载要解密的XML文件
Encryption_and_Dcryption.Decrypt(xmlDoc, key);
if (key != null)
{
key.Clear();
}
xmlDoc.Save(Application.StartupPath + @"\FunctionEnabled.xml");//生成解密后的XML文件
