+      <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:

+	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
