// The following code encrypts the person element in the input XML file and produces encrypted file.

// Load this XML file System.Xml.XmlDocument myDoc = new System.Xml.XmlDocument(); myDoc.Load(@"c:\person.xml"); // Get a specified element to be encrypted System.Xml.XmlElement element =  myDoc.GetElementsByTagName("person")[0] as System.Xml.XmlElement; // Create a new TripleDES key.  System.Security.Cryptography.TripleDESCryptoServiceProvider tDESkey =  new System.Security.Cryptography.TripleDESCryptoServiceProvider(); // Form a Encrypted XML with the Key System.Security.Cryptography.Xml.EncryptedXml encr = new  System.Security.Cryptography.Xml.EncryptedXml(); encr.AddKeyNameMapping("Deskey", tDESkey); // Encrypt the element data System.Security.Cryptography.Xml.EncryptedData ed =  encr.Encrypt(element,"Deskey"); // Replace the existing data with the encrypted data System.Security.Cryptography.Xml.EncryptedXml.ReplaceElement(element,  ed, false); // saves the xml file with encrypted data myDoc.Save(@"c:\encryptedpersons.xml");
