/**
* XML Security Library example: Verifying a simple SAML response with X509 certificate
*
* Verifies a simple SAML response. In addition to regular verification
* we ensure that the signature has only one <dsig:Reference/> element
* with an empty or NULL URI attribute and one enveloped signature transform
* as it is required by SAML specification.
*
* This example was developed and tested with OpenSSL crypto library. The
* certificates management policies for another crypto library may break it.
*
* Usage:
* verify4 <signed-file> <trusted-cert-pem-file1> [<trusted-cert-pem-file2> [...]]
*
* Example (success):
* ./verify4 verify4-res.xml ca2cert.pem cacert.pem
*
* Example (failure):
* ./verify4 verify4-bad-res.xml ca2cert.pem cacert.pem
* In the same time, verify3 example successfully verifies this signature:
* ./verify3 verify4-bad-res.xml ca2cert.pem cacert.pem
*
* This is free software; see Copyright file in the source
* distribution for preciese wording.
