=09When you do 'pgp -kg', you are asked to pick a PGP key size, and given 3 preselected sizes. You can select one of the sizes, or enter your own choice. Actually, the pgp source will allow 2048, but there is a bug in the DOS version (from the compiler) that limits that one to 2047. The international version is identical to the domestic one, except for the RSA code, so everything is interoperable. There is a hacked version that allows 4096 bit keys, and the supersized keys are incompatible.
Are you sure it's a bug in the DOS version? When I did a pgp -kg in my UNIX shell (US version 2.6.2) I also entered 2048 bits and it too created a 2047 bit key instead. Why is there a limit to the size of the key anyway? It's too bad PGP doesn't support any size key (within reason).
