   <title>Why do keys require a signature?</title>
 
-  <p><em>Public keys</em> are so popular because they are known to everyone
-  once they have been <link xref="keys-sync-publish">published</link>. However
-  it is essential to verify if a <em>Public key</em> belongs to the rightful
-  owner or if it is an imitation key.</p>
+  <p>Public keys that are published on
+  <link xref="key-servers-what-are-they">key servers</link> contain the
+  <link xref="key-userid">user ID</link> of the key owner. It is quite easy for
+  someone to create a fake key with a user ID obtained from a key server. To
+  help people in verifying that your key is indeed genuinely yours, you can
+  sign your key and also ask people you know to sign your key.</p>
 
-  <steps>
-    <title>A possible scenario:</title>
-      <item>
-       <p>A and B want to communicate with each other. C wants to stop all
-       communication between them, but A and B do not know this.</p>
-      </item>
-      <item>
-        <p> A creates their <em>Public key</em> and publishes it on a
-       <link xref="key-servers-what-are-they">key server</link>.</p>
-      </item>
-      <item>
-       <p>C <link xref="keys-retrieve-remote">imports</link> A's key and
-       using the information in it, creates a new imitation key. This
-       imitation key will have the same details as A's key but will have a
-       different <link xref="key-fingerprint">fingerprint</link>.</p>
-      </item>
-      <item>
-       <p>C publishes the imitation key on a key server.</p>
-      </item>
-      <item>
-       <p>B imports the key submitted by C, believing that it is A's key.</p>
-      </item>
-      <item>
-       <p>A and B cannot communicate till they realise that the key has been
-       compromised.</p>

-<!--Should the above be described using pictures in a sequence?-aruna-->
+  <p>A <em>web of trust</em> on the Internet is a group of people who have
+  verified and signed each other's public keys. You can also establish a web of
+  trust among the people you want to communicate with by mutually signing each
+  other's keys. In this way, only keys signed by persons in the web of trust
+  are trusted by the other communicating members.</p>

+  <title>How do I sign keys?</title>
 
-  <p>Usually, if you know the person you are communicating with, you can
-  verify the <link xref="key-fingerprint">fingerprint</link> on their key, by
-  asking them in person. In the cases when this is not possible, there is a
-  provision to digitally <em>sign</em> someone's keys if you trust them. You
-  may also sign your own key.</p>
+  <p> When you generate a new key, it is automatically signed by you. Any new
+  <link xref="key-subkeys">subkeys</link> that you generate are signed
+  automatically too. You can sign a key that you have
+  <link xref="keys-retrieve-remote">retrieved</link> from a key server or
+  <link xref="keys-import-export#import">imported</link> into
+  <app>Passwords and Keys</app>. When you sign a key you are vouching for the
+  it, so carefully verify the details of a key before signing it.</p>
 
   <steps>
-    <title>How does signing work?</title>
+    <title>To sign an imported key:</title>
       <item>
-       <p>A and B want to communicate. C wants to stop all communication
-       between them.</p>
+        <p>Select the key.</p>
       </item>
       <item>
-        <p>A creates a public key and requests common friends between her and
-       B to sign the key. She may also choose to sign the key herself. Keys
-       are signed using the <em>Private key</em>.</p>
+       <p>Right click the key and select
+       <guiseq><gui>Properties</gui><gui>Trust</gui></guiseq>.</p>
       </item>
       <item>
-        <p>A publishes the signed key on a key server.</p>
+        <p>Click the <gui style="button">Sign this Key</gui> button.</p>
       </item>
       <item>
-       <p>C publishes an imitation key, after retrieving A's information, but
-       obviously this key will not have any signatures.</p>
+       <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>When B sees two keys in A's name, the signed key will be given more
-       preference and imported, rather than the unsigned key uploaded by C.
-       Signatures can be verified by decrypting the <em>Private keys</em> used
-       to sign, with the <em>Public keys</em> on a key server.</p>
+       <p>You can also select if you want to revoke the signature at a later
+       date by checking the <gui style="checkbox">I can revoke this signature
+       at a later date</gui> checkbox and choose to keep your signature only
+       in the local copy of the key by selecting the
+       <gui style="checkbox">Others may not see this signature</gui>
+       checkbox.</p>
       </item>
       <item>
-        <p>A and B can communicate.</p>
+       <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>Click the <gui style="button">Sign</gui> button to finish.</p>
       </item>
   </steps>
 
-  <p>You can establish a <em>web of trust</em> among the people you want to
-  communicate with by mutually signing each other's keys. In this way, only
-  keys signed by persons in the <em>web of trust</em> are trusted by the
-  communicating members.</p>
