|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/ct.h>
|
|
|
|
CTLOG_STORE *CTLOG_STORE_new_ex(OSSL_LIB_CTX *libctx, const char *propq);
|
|
CTLOG_STORE *CTLOG_STORE_new(void);
|
|
void CTLOG_STORE_free(CTLOG_STORE *store);
|
|
|
|
int CTLOG_STORE_load_default_file(CTLOG_STORE *store);
|
|
int CTLOG_STORE_load_file(CTLOG_STORE *store, const char *file);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
A CTLOG_STORE is a container for a list of CTLOGs (Certificate Transparency
|
|
logs). The list can be loaded from one or more files and then searched by LogID
|
|
(see RFC 6962, Section 3.2, for the definition of a LogID).
|
|
|
|
CTLOG_STORE_new_ex() creates an empty list of CT logs associated with
|
|
the library context I<libctx> and the property query string I<propq>.
|
|
|
|
CTLOG_STORE_new() does the same thing as CTLOG_STORE_new_ex() but with
|
|
the default library context and property query string.
|
|
|
|
The CTLOG_STORE is then populated by CTLOG_STORE_load_default_file() or
|
|
CTLOG_STORE_load_file(). CTLOG_STORE_load_default_file() loads from the default
|
|
file, which is named F<ct_log_list.cnf> in OPENSSLDIR (see the output of
|
|
L<openssl-version(1)>). This can be overridden using an environment variable
|
|
named B<CTLOG_FILE>. CTLOG_STORE_load_file() loads from a caller-specified file
|
|
path instead. Both of these functions append any loaded CT logs to the
|
|
CTLOG_STORE.
|
|
|
|
The expected format of the file is:
|
|
|
|
enabled_logs=foo,bar
|
|
|
|
[foo]
|
|
description = Log 1
|
|
key = <base64-encoded DER SubjectPublicKeyInfo here>
|
|
|
|
[bar]
|
|
description = Log 2
|
|
key = <base64-encoded DER SubjectPublicKeyInfo here>
|
|
|
|
Once a CTLOG_STORE is no longer required, it should be passed to
|
|
CTLOG_STORE_free(). This will delete all of the CTLOGs stored within, along
|
|
with the CTLOG_STORE itself.
|
|
|
|
=head1 NOTES
|
|
|
|
If there are any invalid CT logs in a file, they are skipped and the remaining
|
|
valid logs will still be added to the CTLOG_STORE. A CT log will be considered
|
|
invalid if it is missing a "key" or "description" field.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
Both B<CTLOG_STORE_load_default_file> and B<CTLOG_STORE_load_file> return 1 if
|
|
all CT logs in the file are successfully parsed and loaded, 0 otherwise.
