+    <title>What is Encryption?</title>
+    <para>
+      Encryption is an ancient method of changing readable text to unreadable
+      text that dates back to Egyptian times.  Encryption takes the statement
+      "Evolution" and turns it into something which cannot be read without help
+      through decryption.
+      <example>
+	<title>Encryption Example</title>
+	<para>
+	  Kevin orders an <application>Evolution</application> t-shirt from
+	  Ximian, Inc. over the internet.  He puts in his credit card number
+	  which is 1234-567-8901.  For security, his computer encrypts the
+	  credit card number so it can be safely transmitted over the internet.
+	  The number now is @#$23ui7yr87#@!48970fsd, which holds no intentional
+	  resemblance to the inital number.  When the information gets to
+	  Ximian, Inc. it'll be decrypted into the inital number.
+	</para>
+      </example>
+      Encryption can be used in email in two ways: to verify that the sender is
+      the real sender, and to hide the message while in transmission.
+      <application>Evolution</application> has the capability to do both.

+    <title>Generating your PGP key</title>
+    <para>
+      First, you need to create a PGP key.  To do this, you'll need GPG
+      installed.
+    </para>
+    <tip>
+      <title>GPG Versions</title>
+      <para>
+	This manual covers version 1.0.6 of GPG.  If your version is different,
+	this may not be entirely accurate.  You may find out your version number
+	by typing in: <command>gpg --version</command>.
+	</para>
+      </tip>
+    <para>
+      You can start by typing in: <command>gpg --gen-key</command>.  At the
+      first question, select 1.  The next question asks you about key length.
+      The longer the key, more stronger it is.  However, the longer the key, the
+      longer it takes to generate.  This is your choice.  However, 1024 bits
+      (default) should be adequate.  The next question asks you if you want your
+      key to expire.  Expiring keys make your key invalid after a certain amount
+      of time, so old keys don't float around active.  This is the same concept
+      as a coupon at a supermarket.  Next, you'll type in your Real name, your
+      email address, and a comment.  You should not forge this information, as
+      it is used later to verify who you are.  Assuming that all your
+      information is correct, press "O" to continue.  GPG now asks you for a
+      passphrase.  This is a password which you will need to decrypt and encrypt
+      messages.  This can be any length, with any characters in it.  It is case
+      sensitive, which means that it does know the difference between capital
+      letters and lower-case.  Now your key is generated.  It is recommend you
+      surf the internet, read your email, or write a letter in a word
+      processor.  This help creates randomness in the key.
+    </para>
+    <para>
+      Once this is completed, you'll be dropped back to the command line.
+      Now you can view your key information by typing <command>gpg
+      --list-keys</command>.  You should see something similar to this:

+	  sub 1024g/289sklj3 2001-06-20 [expires: 2002-11-14]
+	</para>
+      </example>
+      You'll now need to upload your public key to a keyserver, so that your
+      friends can use your key.  You'll need to know the ID of your key, which
+      is after the 1024D on the line beginning with pub.  For this example, it
+      is 32j38dk2.  You now type in <command>gpg --send-keys --keyserver
+      wwwkeys.pgp.net 32j38dk2</command>.  Substitute your key ID for 32j38dk2.
+      You will be prompted to type in your password <!-- verify that you need to
+      enter your password here --> and your key will be uploaded for your
+      friends to download.
