<p>Hi all,</p>
<p>I am trying to use <span>CertificateFetcherDirectFetch </span>(<a href="https://github.com/named-data/ndn-cxx/blob/master/src/security/v2/certificate-fetcher-direct-fetch.hpp" class="OWAAutoLink" id="LPlnk214517" previewremoved="true">https://github.com/named-data/ndn-cxx/blob/master/src/security/v2/certificate-fetcher-direct-fetch.hpp</a>)</p>
which is using <span>IncomingFaceId of the data to sent certificate-interest. </span>
