<p>For multi-prime RSA (defined in RFC 8017), there are also one or more &#39;triplet&#39; in an RSA object. A triplet contains three members, <b>r</b>, <b>d</b> and <b>t</b>. <b>r</b> is the additional prime besides <b>p</b> and <b>q</b>. <b>d</b> and <b>t</b> are the exponent and coefficient for CRT calculations.</p>
