Exactly what I needed this morning.
 
If Github just sent you mail asking you to review your ssh key(s) due to their recent security breach, you will see a page that asks you to review your ssh keys by their fingerprint.

Since not everyone knows how to get the fingerprint for the key that they uploaded, I thought I'd help spread the word. (You can verify what I'm saying by reading the ssh-keygen man page.)

Run:
ssh-keygen -l -f ~/.ssh/id_dsa.pub
or
ssh-keygen -l -f ~/.ssh/id_rsa.pub
...depending, of course, on whether you use an RSA or DSA keypair.

You can then compare the output to the output that Github shows you in its verification screen.
