 * 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 &lt;dsig:Signature/&gt; node 
 * itself. The key certificate is written in the &lt;dsig:X509Data/&gt; node.
 * 
 * This example was developed and tested with OpenSSL crypto library. The 
 * certificates management policies for another crypto library may break it.
 * 
 * Usage: 
 *      sign3 &lt;xml-doc&gt; &lt;pem-key&gt; 
 *
 * Example:
 *      ./sign3 sign3-doc.xml rsakey.pem rsacert.pem &gt; 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.
