Have you spoken to Anita? She is very helpful :)

Key management may or may not be covered by export controls. It
depends on whether you are using encryption.

You can perform key agreement (Diffie-Hellman) and not require an
export license. But if you key a block cipher with the shared secret,
you will need a license.

If you are doing key transport (RSA), then you would need a license.
EAP-PSK, with its underlying block cipher, also requires a license.

Authentication does not require a license.

I believe you can ship to banned countries/individuals, but you need a
license that is administered by both Department of Commerce and State
Department. Cookie cutter licenses to get approved for the App Store
usually don't fall under joint jurisdiction.
