  <title>Sign keys</title>

  <p>To show that you trust and vouch for the genuineness of someone's key, you
  can sign it. A person's key must be signed only after you compare the
  <link xref="pgp-userid">user ID</link> on the key with a valid proof of their
  identity, such as a passport, driver's license, or similar. If the two IDs
  match, the key is said to be trustworthy.</p>

  <steps>
    <title>To sign a key:</title>
    <item>
      <p>Import the <link xref="pgp-retrieve-remote">remote key</link> or
      <link xref="pgp-import">keyfile</link> containing the key to be signed
      into <app>Passwords and Keys</app>.</p>
    </item>
    <item>
      <p>From the list of <gui>GnuPG keys</gui> select the imported key.</p>
    </item>
    <item>
      <p>Right click the key and select
      <guiseq><gui>Properties</gui><gui>Trust</gui></guiseq>.</p>
    </item>
    <item>
      <p>Press the <gui style="button">Sign this Key</gui> button.</p>
    </item>
    <item>
      <p>Depending on how carefully you have checked the key, choose one out of
      <gui style="radiobutton">Not at all</gui>,
      <gui style="radiobutton">Casually</gui> or
      <gui style="radiobutton">Very carefully</gui>.</p>
    </item>
    <item>
      <p>Decide if you want to revoke your signature at a later date and if you
      want to make your signature public, by ticking the checkboxes
      provided.</p>
    </item>
    <item>
      <p>When you own more than one PGP key, select the key you want to sign
      with, from the list next to <gui>Signer</gui>.</p>
    </item>
    <item>
      <p>Press the <gui style="button">Sign</gui> button to finish.</p>
    </item>
  </steps>

  <note style="info">
    <title>Can I sign my own keys?</title>
    <p>When you <link xref="pgp-create">create</link> a new
    <gui>GnuPG key</gui>, it is automatically signed by you. Any new subkeys
    <link xref="subkeys-add">created</link> using a <gui>GnuPG key</gui>, will
    also be signed automatically.</p>
