20 #include "keystructs.h"
23 #include "onak_conf.h"
27 * keydb_fetchchar - Fetches a char from a file.
29 static int keydb_fetchchar(void *fd, size_t count, unsigned char *c)
31 return !(read( *(int *) fd, c, count));
35 * keydb_putchar - Puts a char to a file.
37 static int keydb_putchar(void *fd, unsigned char c)
39 return !(write( *(int *) fd, &c, sizeof(c)));
43 * initdb - Initialize the key database.
45 * This is just a no-op for flat file access.
52 * cleanupdb - De-initialize the key database.
54 * This is just a no-op for flat file access.
61 * fetch_key - Given a keyid fetch the key from storage.
62 * @keyid: The keyid to fetch.
63 * @publickey: A pointer to a structure to return the key in.
65 * We use the hex representation of the keyid as the filename to fetch the
66 * key from. The key is stored in the file as a binary OpenPGP stream of
67 * packets, so we can just use read_openpgp_stream() to read the packets
68 * in and then parse_keys() to parse the packets into a publickey
71 int fetch_key(uint64_t keyid, struct openpgp_publickey **publickey)
73 struct openpgp_packet_list *packets = NULL;
77 snprintf(keyfile, 1023, "%s/0x%llX", config.file_dbpath,
79 fd = open(keyfile, O_RDONLY); // | O_SHLOCK);
82 read_openpgp_stream(keydb_fetchchar, &fd, &packets);
83 parse_keys(packets, publickey);
91 * store_key - Takes a key and stores it.
92 * @publickey: A pointer to the public key to store.
94 * Again we just use the hex representation of the keyid as the filename
95 * to store the key to. We flatten the public key to a list of OpenPGP
96 * packets and then use write_openpgp_stream() to write the stream out to
99 int store_key(struct openpgp_publickey *publickey)
101 struct openpgp_packet_list *packets = NULL;
102 struct openpgp_packet_list *list_end = NULL;
103 struct openpgp_publickey *next = NULL;
107 snprintf(keyfile, 1023, "%s/0x%llX", config.file_dbpath,
108 get_keyid(publickey) & 0xFFFFFFFF);
109 fd = open(keyfile, O_WRONLY | O_CREAT, 0664); // | O_EXLOCK);
112 next = publickey -> next;
113 publickey -> next = NULL;
114 flatten_publickey(publickey, &packets, &list_end);
115 publickey -> next = next;
117 write_openpgp_stream(keydb_putchar, &fd, packets);
125 * delete_key - Given a keyid delete the key from storage.
126 * @keyid: The keyid to delete.
128 * This function deletes a public key from whatever storage mechanism we
129 * are using. Returns 0 if the key existed.
131 int delete_key(uint64_t keyid)
135 snprintf(keyfile, 1023, "%s/0x%llX", config.file_dbpath,
138 return unlink(keyfile);
142 * Include the basic keydb routines.
