CTLOG_STORE_NEW(3ossl) OpenSSL CTLOG_STORE_NEW(3ossl)
NAME
CTLOG_STORE_new_ex, CTLOG_STORE_new, CTLOG_STORE_free,
CTLOG_STORE_load_default_file, CTLOG_STORE_load_file - Create and
populate a Certificate Transparency log list
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);
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 libctx and the property query string propq.
CTLOG_STORE_new(3) 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 ct_log_list.cnf in OPENSSLDIR (see the
output of openssl-version(1)). This can be overridden using an
environment variable named 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. If the argument is NULL, nothing is
done.
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.
RETURN VALUES
Both CTLOG_STORE_load_default_file and CTLOG_STORE_load_file return 1
if all CT logs in the file are successfully parsed and loaded, 0
otherwise.
