Try It!

1. 8Ensure that you have completed all the procedures in Getting Started with XML Digital Signatures.
2. Copy the signature_template.store.rsa.xml and paste it into a text file. Save the file as signature_template.store.rsa.xml.
3. Copy the JScript listing above, and paste it into a text file. Save the file as storeProp.js, in the same directory where you saved signature_template.store.rsa.xml.
4. From a command prompt, navigate to this directory, then type "cscript storeProp.js".

   Note   Under operating systems other than Windows 2000 or Windows XP, you might need to install Windows Scripting Host (to run wscript.exe or cscript.exe), if it is not already installed.

5. Verify that your output is similar to that listed in the Output topic.
