if a user A has a secret (signing/certification) key K and two e-mail
adresses A1 and A2, the OpenPGP key consists of the following packets:
* public key K packet
* user ID A1 packet
* signature packet over K and A1 signed with K
* user ID A2 packet
* signature packet over K and A2 signed with K
Is it possible to create encryption keys E1 and E2 bound respectively to
A1 and A2?
Looking at the packets after E1/E2 creation we got only public key
packets binding E1/E2 to K but not to the adresses:
* public key E1 packet
* signature packet over K and E1 signed with K
* public key E2 packet
* signature packet over K and E2 signed with K
How to create a signature packet over K, A1 and E1 signed with K in GnuPG?
