14 * merge_keys - Takes 2 public keys and merges them.
15 * @a: The old key. The merged key is returned in this structure.
16 * @b: The new key. The changed from old to new keys are returned in this
19 * This function takes 2 keys and merges them. It then returns the merged
20 * key in a and the difference between this new key and the original a
21 * in b (ie newb contains the minimum amount of detail necessary to
22 * convert olda to newa). The intention is that olda is provided from
23 * internal storage and oldb from the remote user. newa is then stored in
24 * internal storage and newb is sent to all our keysync peers.
26 int merge_keys(struct openpgp_publickey *a, struct openpgp_publickey *b);
29 * get_signed_packet - Gets a signed packet from a list.
30 * @packet_list: The list of packets to look in.
31 * @packet: The packet to look for.
33 * Walks through the signedpacket_list looking for the supplied packet and
34 * returns it if found. Otherwise returns NULL.
36 struct openpgp_signedpacket_list *find_signed_packet(
37 struct openpgp_signedpacket_list *packet_list,
38 struct openpgp_packet *packet);
41 * merge_packet_sigs - Takes 2 signed packets and merges their sigs.
42 * @old: The old signed packet.
43 * @new: The new signed packet.
45 * Takes 2 signed packet list structures and the sigs of the packets on
46 * the head of these structures. These packets must both be the same and
47 * the fully merged structure is returned in old and the minimal
48 * difference to get from old to new in new.
