Resource: signature_template.rsa.xml (createKeyFromCSP Method)

  • Artikel

 

[This sample code uses features that were implemented in MSXML 5.0 for Microsoft Office Applications. XML digital signatures are not supported in MXSML 6.0 and later.]

The KeyFromCSP example uses a signature template file that contains internally referenced text data to be signed. This file has the following characteristics:

  • The signed text data, "Hello, World!", is held as the content of a <ds:Object Id="HelloWorld"> element.

  • The algorithm used to generate the signature is http://www.w3.org/2000/09/xmldsig\#dsa-sha1.

  • The signature information, <ds:KeyInfo>, is missing and will be added when the data is signed.
