10
11 #include <openssl/ct.h>
12
13 CTLOG_STORE *CTLOG_STORE_new(void);
14 void CTLOG_STORE_free(CTLOG_STORE *store);

16 int CTLOG_STORE_load_default_file(CTLOG_STORE *store);
17 int CTLOG_STORE_load_file(CTLOG_STORE *store, const char *file);

19=head1 DESCRIPTION
20
21A CTLOG_STORE is a container for a list of CTLOGs (Certificate Transparency
22logs). The list can be loaded from one or more files and then searched by LogID
23(see RFC 6962, Section 3.2, for the definition of a LogID).
24
25CTLOG_STORE_new() creates an empty list of CT logs. This is then populated
26by CTLOG_STORE_load_default_file() or CTLOG_STORE_load_file().
27CTLOG_STORE_load_default_file() loads from the default file, which is named
28"ct_log_list.cnf" in OPENSSLDIR (see the output of L<version>). This can be
29overridden using an environment variable named "CTLOG_FILE".
30CTLOG_STORE_load_file() loads from a caller-specified file path instead.
31Both of these functions append any loaded CT logs to the CTLOG_STORE.
32
33The expected format of the file is:
34
35 enabled_logs=foo,bar
36
37 [foo]
38 description = Log 1
39 key = <base64-encoded DER SubjectPublicKeyInfo here>
40
41 [bar]
42 description = Log 2
43 key = <base64-encoded DER SubjectPublicKeyInfo here>
44
45Once a CTLOG_STORE is no longer required, it should be passed to
46CTLOG_STORE_free(). This will delete all of the CTLOGs stored within, along
47with the CTLOG_STORE itself.
48
49=head1 NOTES
50
51If there are any invalid CT logs in a file, they are skipped and the remaining
52valid logs will still be added to the CTLOG_STORE. A CT log will be considered
53invalid if it is missing a "key" or "description" field.
54
55=head1 RETURN VALUES
56
57Both B<CTLOG_STORE_load_default_file> and B<CTLOG_STORE_load_file> return 1 if
58all CT logs in the file are successfully parsed and loaded, 0 otherwise.
