<p><a href="https://tools.ietf.org/html/rfc4880#section-5.5">RFC4480 5.5</a>:
A key material packet contains all the information about a public or
private key. There are four variants of this packet type, and two
major versions.</p>
<p>A Public-Key packet starts a series of packets that forms an OpenPGP
key (sometimes called an OpenPGP certificate).</p></div>
