  This function receives a PKCS7 formatted signature, and then verifies that

  Note that this function does not validate the certificate chain.

  Applications for custom EKU's are quite flexible. For example, a policy EKU
  may be present in an Issuing Certificate Authority (CA), and any sub-ordinate
  certificate issued might also contain this EKU, thus constraining the
  sub-ordinate certificate.  Other applications might allow a certificate
  embedded in a device to specify that other Object Identifiers (OIDs) are
  present which contains binary data specifying custom capabilities that
  the device is able to do.
