<p>CTLOG_STORE_new, CTLOG_STORE_free, CTLOG_STORE_load_default_file, CTLOG_STORE_load_file - Create and populate a Certificate Transparency log list</p>
<h1 id="SYNOPSIS">SYNOPSIS</h1>
<pre><code> #include <openssl/ct.h>
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);</code></pre>
<h1 id="DESCRIPTION">DESCRIPTION</h1>
<p>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).</p>
<p>CTLOG_STORE_new() creates an empty list of CT logs. This 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 <a href="/../man1/version.html">version</a>). 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.</p>
<p>The expected format of the file is:</p>
<pre><code> enabled_logs=foo,bar
[foo]
description = Log 1
key = <base64-encoded DER SubjectPublicKeyInfo here>
[bar]
description = Log 2
key = <base64-encoded DER SubjectPublicKeyInfo here></code></pre>
<p>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.</p>
<h1 id="NOTES">NOTES</h1>
<p>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.</p>
<h1 id="RETURN-VALUES">RETURN VALUES</h1>
<p>Both <b>CTLOG_STORE_load_default_file</b> and <b>CTLOG_STORE_load_file</b> return 1 if all CT logs in the file are successfully parsed and loaded, 0 otherwise.</p>
