14 #include "keystructs.h"
18 * initdb - Initialize the key database.
19 * @readonly: If we'll only be reading the DB, not writing to it.
21 * This function should be called before any of the other functions in
22 * this file are called in order to allow the DB to be initialized ready
25 void initdb(bool readonly);
28 * cleanupdb - De-initialize the key database.
30 * This function should be called upon program exit to allow the DB to
31 * cleanup after itself.
36 * starttrans - Start a transaction.
38 * Start a transaction. Intended to be used if we're about to perform many
39 * operations on the database to help speed it all up, or if we want
40 * something to only succeed if all relevant operations are successful.
42 bool starttrans(void);
45 * endtrans - End a transaction.
52 * fetch_key - Given a keyid fetch the key from storage.
53 * @keyid: The keyid to fetch.
54 * @publickey: A pointer to a structure to return the key in.
55 * @intrans: If we're already in a transaction.
57 * This function returns a public key from whatever storage mechanism we
60 * TODO: What about keyid collisions? Should we use fingerprint instead?
62 int fetch_key(uint64_t keyid, struct openpgp_publickey **publickey, bool intrans);
65 * store_key - Takes a key and stores it.
66 * @publickey: A pointer to the public key to store.
67 * @intrans: If we're already in a transaction.
68 * @update: If true the key exists and should be updated.
70 * This function stores a public key in whatever storage mechanism we are
71 * using. intrans indicates if we're already in a transaction so don't
72 * need to start one. update indicates if the key already exists and is
75 * TODO: Do we store multiple keys of the same id? Or only one and replace
78 int store_key(struct openpgp_publickey *publickey, bool intrans, bool update);
81 * delete_key - Given a keyid delete the key from storage.
82 * @keyid: The keyid to delete.
83 * @intrans: If we're already in a transaction.
85 * This function deletes a public key from whatever storage mechanism we
86 * are using. Returns 0 if the key existed.
88 int delete_key(uint64_t keyid, bool intrans);
91 * fetch_key_text - Trys to find the keys that contain the supplied text.
92 * @search: The text to search for.
93 * @publickey: A pointer to a structure to return the key in.
95 * This function searches for the supplied text and returns the keys that
98 int fetch_key_text(const char *search, struct openpgp_publickey **publickey);
101 * update_keys - Takes a list of public keys and updates them in the DB.
102 * @keys: The keys to update in the DB.
103 * @sendsync: If we should send a keysync mail.
105 * Takes a list of keys and adds them to the database, merging them with
106 * the key in the database if it's already present there. The key list is
107 * update to contain the minimum set of updates required to get from what
108 * we had before to what we have now (ie the set of data that was added to
109 * the DB). Returns the number of entirely new keys added.
111 * If sendsync is true then we send out a keysync mail to our sync peers
114 int update_keys(struct openpgp_publickey **keys, bool sendsync);
117 * keyid2uid - Takes a keyid and returns the primary UID for it.
118 * @keyid: The keyid to lookup.
120 * This function returns a UID for the given key. Returns NULL if the key
123 char *keyid2uid(uint64_t keyid);
126 * getkeysigs - Gets a linked list of the signatures on a key.
127 * @keyid: The keyid to get the sigs for.
128 * @revoked: Is the key revoked?
130 * This function gets the list of signatures on a key. Used for key
131 * indexing and doing stats bits. If revoked is non-NULL then if the key
132 * is revoked it's set to true.
134 struct ll *getkeysigs(uint64_t keyid, bool *revoked);
137 * cached_getkeysigs - Gets the signatures on a key.
138 * @keyid: The key we want the signatures for.
140 * This function gets the signatures on a key. It's the same as the
141 * getkeysigs function above except we use the hash module to cache the
143 struct ll *cached_getkeysigs(uint64_t keyid);
146 * getfullkeyid - Maps a 32bit key id to a 64bit one.
147 * @keyid: The 32bit keyid.
149 * This function maps a 32bit key id to the full 64bit one. It returns the
150 * full keyid. If the key isn't found a keyid of 0 is returned.
152 uint64_t getfullkeyid(uint64_t keyid);
155 * iterate_keys - call a function once for each key in the db.
156 * @iterfunc: The function to call.
157 * @ctx: A context pointer
159 * Calls iterfunc once for each key in the database. ctx is passed
160 * unaltered to iterfunc. This function is intended to aid database dumps
161 * and statistic calculations.
163 * Returns the number of keys we iterated over.
