I have a communication partner that is using some script that does not work well with subkeys. Now, my gpg key is a normal key [SC] with three subkeys for E,S and A specifically.

For my communication partner, I'd like to extract the [E] subkey and create a new "full fledged" gpg key with this subkey as it's only public key, so I can give that to my communication partner to encrypt to.

Is that possible?
