<p>Hi all,<br>
if a user A has a secret (signing/certification) key K and two
e-mail adresses A1 and A2, the OpenPGP key consists of the
following packets:</p>
<ul>
<li>public key K packet</li>
<li>user ID A1 packet</li>
<li>signature packet over K and A1 signed with K</li>
<li>user ID A2 packet</li>
<li>signature packet over K and A2 signed with K</li>
</ul>
<p>Is it possible to create encryption keys E1 and E2 bound
respectively to A1 and A2?</p>
<p>Looking at the packets after E1/E2 creation we got only public
key packets binding E1/E2 to K but not to the adresses:<br>
</p>
<ul>
<li>public key E1 packet</li>
<li>signature packet over K and E1 signed with K</li>
<li>public key E2 packet</li>
<li>signature packet over K and E2 signed with K</li>
</ul>
<p>How to create a signature packet over K, A1 and E1 signed with K
in GnuPG?</p>
<p>/Ann.<br>
