<Signature> Element (ClickOnce Deployment)

Contains the necessary information to digitally sign this deployment manifest.

<Signature> 
   XML signature information 
</Signature>

Signing a deployment manifest using an envelope signature is optional, but recommended. For more information about signing XML files see the World Wide Web Consortium Recommendation, "XML-Signature Syntax and Processing," described at http://www.w3.org/TR/xmldsig-core/.

If you want to sign your manifest, hashes must be provided for all files. A manifest with files that are not hashed cannot be signed, because users cannot verify the contents of unhashed files.

The following code example illustrates a Signature element in a deployment manifest used in a ClickOnce deployment.

<Signature xmlns="http://www.w3.org/2000/09/xmldsig#">
