A key fingerprint is a name for a key and it is what the user can see. A key fingerprint is generated by an MD5 hash based on the public key data.

You can view the key fingerprint for a client in the key panel. To display the key panel, press Stop-K on a Sun keyboard or Ctrl-Pause-K on a non-Sun or PC keyboard. To verify the authenticity of a client key, you can compare the key fingerprint displayed in the client's key panel with the one shown by the utkeyadm command for the same client.
