  <p class="level0">If <a Class="emphasis" href="./CURLOPT_SSL_VERIFYPEER.html">CURLOPT_SSL_VERIFYPEER</a> is zero and you avoid verifying the server's certificate, <a Class="emphasis" href="./CURLOPT_CAINFO.html">CURLOPT_CAINFO</a> need not even indicate an accessible file. 
  <p class="level0">This option is by default set to the system path where libcurl's cacert bundle is assumed to be stored, as established at build time. 
  <p class="level0">If curl is built against the NSS SSL library, the NSS PEM PKCS&#35;11 module (libnsspem.so) needs to be available for this option to work properly. <a name="DEFAULT"></a><h2 class="nroffsh">DEFAULT</h2>
