/**
 * This class is a sample implementation of the certificate info factory interface. The signature parameters in this
 * case has been put in prompt fields. Among others there are user name and user password. They can be used to read the
 * security settings. The other opportunity is to read security settings direct. This is illustrated in
 * <code>getCertificateInfo(Engine)</code>. The custom certificate info factory, if set, has a higher priority than the
 * default certificate info factory, that can be set through configuration.
