In this lab you will:

a. Install and configure the Pretty Good Privacy (PGP) software
b. Create a public-key pair for yourself with a valid email address
c. Install the intructors public key into your key ring
d. Send an encrypted, signed email to the instructor

1.  If you do not have PGP Desktop installed, you can install the free
    Microsoft Windows version from here:

2.  Install the PGP software.  The installation should be relatively
    self explanatory if you've ever installed any software before.  It
    will prompt you to configure an email account.  I recommend you use
    a legitimate one.  It will ask you to choose a password.  You should
    really try not to lose this password.  It will create a key pair
    for you.  You also do not want to lose these keys.  Here are some
    links that do a pretty good job of describing the installation:

3.  Once you've configured the software and setup a key run the PGP
    software and click on "PGP Keys" and then on "Search for Keys".
    You should be able to search for my key by typiing in my depaul
    email address.  Add this key to your keyring.

4.  If your PGP software was setup to be integrated with your email
    client, you can click on my key and then click on "Email this
    Receipient".  Your email appication should open up and you can
    then write me a message that will be encrypted and signed to
    me.  I suggest simply writing the following text:

       This is <your name>, here is my encrypted message for IT 263

    If it didn't detect your email client, you should still be able
    to encrypt and sign a message.  This would normally involve you
    writing your message, then selecting all the text, then using
    the icon in the toolbar, select the PGP option to encrypt and
    sign the selected text.  Here are some additional links that can
    help you make all this happen:
