Signing XML documents

[Todd Richardson]

I am working to develop and application which will
generate XML files. I would like to sign these documents
at the time of creation to allow someone to verify them at
a later date. What would be the best way to sign an XML
document using ASP.NET. I have considered using the
SIGNTOOL.EXE from Microsoft and simply use VBSCRIPT to use
the command. Is there an simple and easy method from
ASP.NET to apply a digital signature to the XML files. We
plan to use an SSL certificate to sign the documents.

Thanks!

Have you taken a look at the classes in the System.Security.Cryptography.Xml
namespace?

I have seen it, but I could not find any code samples of
how to implement it.

You may try to find some sample code from this link:

frlrfSystemSecurityCryptographyXml.asp

For exmaple, from the signedXML method.
