Hello all,

Thanks for all the help.  I'm learning this stuff pretty quickly.  The=20
resources have been very useful.

I'm currently figuring out subkeys.  This is what I know so far:

 - I have a unique DSA key for signing.
 - I can have multiple ElGamal keys for encription.  These are the
   subkeys.
 - The command below tells me that my 1024-bit DSA key has a KeyID
   0FEBCEC3, and that of my 2048-bit ElGamal key is 0D1C25EC.

So far so good?  Now my questions:

-  What's the difference between the fingerprint and the KeyID?
-  Does only the signing key have a fingerprint?
-  Which KeyID do I use to generate my public key?
   I figure it must be the ElGamal one.

Thanks for the help,
