Key sizes, public vs. secret key

[Ryan Malayter]

The Digital Signature Algorithm is limited to 1024 bits. If you make an
ElGamal Sign+encrypt or RSA key, you can make your public key larger
than 1024 bits, but you may have some interoperability problems with
users of other OpenPGP systems since those algorithms are not required
in the standard.

Now, as for the 8192 bits private vs. 1024 bit public key sizes, I don't
believe you can create such a keypair with any algorithm used in GnuPG.
