RSA 1024 ridiculous /8192 is sublime

[Newton Hammet]

gnupg as distributed may not be generating larger than 4096 bit keys
but it is easy enough to (or was in the past) to modify the source code
in I think one place and change it to whatever you want.

In my case I was able to successfully generate a 8192-bit RSA key
and tested it with encryption, decryption, signing, etc. and it
worked.

My Hard drive, like my closet and garage, however is resisting
my attempts to figure out where I put this particular piece of
enterprise. (I think it was back in 2003 +/-).

I will keep looking for it.
