17 * add_key - Takes a key and adds it to the keyserver.
18 * @key: The public key to add.
20 * This function takes a public key and adds it to the keyserver.
21 * It first of all sees if we already have the key locally. If we do then
22 * we retrieve it and merge the two keys. We then store the resulting key
23 * (or just the original we received if we don't already have it). We then
24 * send out the appropriate updates to our keyserver peers.
26 int add_key(struct openpgp_publickey *key);
29 * parse_keys - Process a stream of packets for public keys + sigs.
30 * @packets: The packet list to parse.
31 * @keys: The returned list of public keys.
33 * This function takes an list of OpenPGP packets and attempts to parse it
34 * into a list of public keys with signatures and subkeys.
36 * Returns a count of how many keys we parsed.
38 int parse_keys(struct openpgp_packet_list *packets,
39 struct openpgp_publickey **keys);
42 * debug_packet - Print debug info about a packet
43 * @packet: The packet to display.
45 * This function takes an OpenPGP packet and displays some information
46 * about it to stdout. Useful for debugging purposes or curiousity about
47 * an OpenPGP packet stream.
49 int debug_packet(struct openpgp_packet *packet);
52 * read_openpgp_stream - Reads a stream of OpenPGP packets.
53 * @getchar_func: The function to get the next character from the stream.
54 * @ctx: A pointer to the context structure for getchar_func.
55 * @packets: The outputted list of packets.
56 * @maxnum: The maximum number of keys to read. 0 means unlimited.
58 * This function uses getchar_func to read characters from an OpenPGP
59 * packet stream and reads the packets into a linked list of packets
60 * ready for parsing as a public key or whatever. maxnum allows you to
61 * specify the maximum number of keys to read. Note that if this is used
62 * then only the public key component of the last key will be returned,
63 * none of the other packets of the key will be read.
65 int read_openpgp_stream(int (*getchar_func)(void *ctx, size_t count,
68 struct openpgp_packet_list **packets,
72 * write_openpgp_stream - Reads a stream of OpenPGP packets.
73 * @putchar_func: The function to put the next character to the stream.
74 * @ctx: A pointer to the context structure for putchar_func.
75 * @packets: The list of packets.
77 * This function uses putchar_func to write characters to an OpenPGP
78 * packet stream from a linked list of packets.
80 int write_openpgp_stream(int (*putchar_func)(void *ctx, size_t count,
83 struct openpgp_packet_list *packets);
86 * flatten_publickey - Convert a publickey to an OpenPGP packet list.
87 * @key: The public key.
88 * @packets: The outputted packet list.
89 * @list_end: The end of the packet list.
91 * This function converts public key structure to a linked list of OpenPGP
92 * packets ready for outputing or storage. If we're not appending to an
93 * existing list then both packets & list_end will be pointers to NULLs,
94 * other wise packets should point to the start of the list and list_end
95 * to the end so we can append to the end.
