Am I Missing Something?

[Carlos Williams]

I am trying to generate a key and start using it with Mozilla Thunderbird /
Enigmail & I am obviously missing something. I generated a key on my system
using the following command:

cwilliams at tunafish:~$ gpg --gen-key

You can see below exactly what I did and I am now unclear once I created
this key how to start using it with my email client. Am I missing something?

Please select what kind of key you want:
   (1) DSA and Elgamal (default)
   (2) DSA (sign only)
   (5) RSA (sign only)
Your selection? 1
DSA keypair will have 1024 bits.
ELG-E keys may be between 1024 and 4096 bits long.
What keysize do you want? (2048)
Requested keysize is 2048 bits
Please specify how long the key should be valid.
         0 = key does not expire
      <n>  = key expires in n days
      <n>w = key expires in n weeks
      <n>m = key expires in n months
      <n>y = key expires in n years
Key is valid for? (0)
Key does not expire at all
Is this correct? (y/N) y

You need a Passphrase to protect your secret key.

We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.

Now I can see the following when I list the keys:

cwilliams at tunafish:~$ gpg --list-keys
/home/carl/.gnupg/pubring.gpg

uid                  Carlos Williams <cwilliams at example.org>
sub   2048g/XXXXXXX 2008-05-29

Thanks for any help!
