* tools/gpg-wks.h (WKS_DRAFT_VERSION): New. * tools/wks-receive.c (new_part): Move test wks draft version to ... (t2body): new callback. (wks_receive): Register this callback. * tools/gpg-wks-server.c (send_confirmation_request): Emit draft version header. (send_congratulation_message): Ditto. * tools/gpg-wks-client.c (decrypt_stream_parm_s): New. (decrypt_stream_status_cb): Check DECRYTPION_KEY status. (decrypt_stream): Get infor from new callback. (process_confirmation_request): New arg 'mainfpr'. Check that it matches the decryption key. (read_confirmation_request): Check that the decryption key has been generated by us.

This patch also adds a check to only send a confirmation when the
decryption has been done by an ultimately trusted (self-generated)
key.
