XML-File Integrity Check Standard

[xoncegame]

I have a need to incorporate some kind of integrity check of XML file into it's structure. Considering an XmlDSig as a standard, I wonder is there any way to get rid of asymmetric key (authentication) feature? Or maybe there is some other standard for the sole purpose of XML file integrity validation?SHA1 is a hash function and doesn't require any key to be generated. It's enough for integrity check, on it's own. It's evident that generation of a temporary assymetric key for the sole integrity check purpose is an excessive operation. Using C# there are some pitfalls also exists.If key is not assigned to SignedXml.SignedKey property, SignedXml.ComputeSignature method cause 'Signing key is not loaded' exception.
