Encrypt XML SubtreeEncrypt an entire subtree within an XML document <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> </head> <body> <% set xml = Server.CreateObject("Chilkat.Xml") ' First, build a sample XML document: set xml = Server.CreateObject("Chilkat.Xml") xml.Tag = "stocks" Set xmlM = xml.NewChild("Microsoft","") xmlM.NewChild2 "symbol","MSFT" xmlM.NewChild2 "recentPrice","34.50" Set xmlG = xml.NewChild("Google","") xmlG.NewChild2 "symbol","GOOG" xmlG.NewChild2 "recentPrice","679.00" ' Display the unencrypted XML: Response.Write xml.GetXml() & "<br>" ' This is the XML displayed: ' <stocks> ' <Microsoft> ' <symbol>MSFT</symbol> ' <recentPrice>34.50</recentPrice> ' </Microsoft> ' <Google> ' <symbol>GOOG</symbol> ' <recentPrice>679.00</recentPrice> ' </Google> ' </stocks> ' The goal is to encrypt the "Microsoft" sub-tree. ' The EncryptContent method encryptes the content ' within a single XML node (not an entire sub-tree). ' Therefore, to encrypt a sub-tree, you must first ' compress it into a single node, and then encrypt it. xmlM.ZipTree ' Now encrypt the content using 128-bit AES encryption: xmlM.EncryptContent "secretPassword" ' Display the XML with the encrypted sub-tree: Response.Write xml.GetXml() & "<br>" ' This is displayed: ' <stocks> ' <Microsoft><![CDATA ' [JkiMcoK3Mi198rT30KvicDEzu5WuJgMH+8KS0UZbcRE ' 2CtdXplphV0iCdPMYnS01O6Ly6S4QCQSReMCshG/V3 ' 8btJIZv/VLG9JZRsQk0bBafMhx7B2fQfm8YENke/JIM ' ]]> </Microsoft> ' <Google> ' <symbol>GOOG</symbol> ' <recentPrice>679.00</recentPrice> ' </Google> ' </stocks> ' Now decrypt and unzip: xmlM.DecryptContent "secretPassword" success = xmlM.UnzipTree() If (success <> 1) Then Response.Write "Failed to unzip tree" & "<br>" End If ' Display the restored document: Response.Write xml.GetXml() & "<br>" %> </body> </html> |
