Verifying Signed XML files.

[wanni]

Hi All,
I have a signed XML file which i want to use in my JavaScript. Before doing any operation using XML file data , i want to verify XML file signature (to verify file is not tempered with third party attack).

Is this behaviour possible in JavaScript. I want to support this feature both in Windows XP and Windows Vista.

Note For Moderators: I have mistakenly post this in InSights forums. Please forgive me.

Regards.

What exactly do you mean by verifying an XML file? Do you mean validating?

I just want to check the signature of XML file (i.e. signing and verification operation). XML file is signed using private key and i just want to check whether signature is valid or not. I am using Internet Explorer (Verison 7) and want to test on Windows XP and Windows Vista.

You could use some server-side code for this, e.g. see http://msdn.microsoft.com/en-us/library/ms229950.aspx for .NET. You could make a request using Ajax.

I dont want to use .Net Enviroment. I signed my XML file through certificate private key and want to verify XML file signtaure in Java Script or ActiveX.

I am using VC 6 enviroment.

Is there any way i can achieve this functionality.

That was only one example, of course. You could probably use other languages. You may also find controls for ActiveX. What server-side languages can you use?

Regarding server side lanuages my first preference would be ASP.
Is there any link or documentataion where i could get a help regarding how to use ActiveX (or its functions) for achieving desired functionality.

Check the documentation on ASP to see if there's something available that does what you require.

For ActiveX, see http://msdn.microsoft.com/en-us/library/aa751972.aspx.
