* XML Security Library example: Signing a file with a dynamicaly created template and an X509 certificate.
*
* Signs a file using a dynamicaly created template, key from PEM file and
* an X509 certificate. The signature has one reference with one enveloped
* transform to sign the whole document except the <dsig:Signature/> node
* itself. The key certificate is written in the <dsig:X509Data/> node.
*
* This example was developed and tested with OpenSSL crypto library. The
* certificates management policies for another crypto library may break it.
*
* Usage:
* sign3 <xml-doc> <pem-key>
*
* Example:
* ./sign3 sign3-doc.xml rsakey.pem rsacert.pem > sign3-res.xml
*
* The result signature could be validated using verify3 example:
* ./verify3 sign3-res.xml rootcert.pem
*
* This is free software; see Copyright file in the source
* distribution for preciese wording.
