You asked "Is there an easy way to generate keys larger than 1024 bits?" I answered No. This is true, there is no way, currently, in PGP, to generate keys larger than 1024 bits. Is there a design flaw? No. It was an implementation decision. It does not mean that the key size will not be increased in a future release.

PGP23a for DOS will create a 1264 bit key if you enter the key size manually at the prompt. Key generation will take a long time, and secret key operations (decryption and signing) will be slow. Not that anyone actually needs a 1264 bit key, but it is possible.
