28 * get_keyid - Given a public key returns the keyid.
29 * @publickey: The key to calculate the id for.
31 * This function returns the key id for a given public key.
33 uint64_t get_keyid(struct openpgp_publickey *publickey);
36 * get_fingerprint - Given a public key returns the fingerprint.
37 * @publickey: The key to calculate the id for.
38 * @fingerprint: The fingerprint (must be at least 20 bytes of space).
39 * @len: The length of the returned fingerprint.
41 * This function returns the fingerprint for a given public key. As Type 3
42 * fingerprints are 16 bytes and Type 4 are 20 the len field indicates
43 * which we've returned.
45 unsigned char *get_fingerprint(struct openpgp_packet *packet,
46 unsigned char *fingerprint,
50 * get_packetid - Given a PGP packet returns the keyid.
51 * @packet: The packet to calculate the id for.
53 * This function returns the key id for a given PGP packet.
55 uint64_t get_packetid(struct openpgp_packet *packet);
58 * get_skshash - Given a public key returns the SKS hash for it.
59 * @publickey: The key to calculate the hash for.
60 * @skshash: Hash structure to sort the result in.
62 * This function returns the SKS hash for a given public key. This
63 * is an MD5 hash over a sorted list of all of the packets that
64 * make up the key. The caller should allocate the memory for the
67 void get_skshash(struct openpgp_publickey *publickey, struct skshash *hash);
70 * parse_skshash - Parse a string into an SKS hash structure.
71 * @search: The string representing the SKS hash.
72 * @hash: A pointer to the structure to store the hash in.
74 * Takes a string and tries to parse it as an SKS hash hex
75 * representation. Puts the hash into the supplied structure
76 * if successful. Returns 1 if we parsed something ok, 0 if
79 int parse_skshash(char *search, struct skshash *hash);
