XML Signature with Barcoded Form

[jnicholas330]

I have a form that has a number of fields that need to be filled out. When this is complete, the user should digitally sign (with a certificate) the form. However, due to legal requirements, the form must then be printed and mailed back to the organization. Is it possible to encode the signature data within the barcode (PDF417) so it can be validated?

After finding the sign function and playing around with the resulting XML Signature, I've found it's just too much data to put in a barcode, even a 2D one.
