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_ex() creates an empty list of CT logs associated with the library context <i>libctx</i> and the property query string <i>propq</i>.</p> <p>CTLOG_STORE_new() does the same thing as CTLOG_STORE_new_ex() but with the default library context and property query string.</p> <p>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 <i>ct_log_list.cnf</i> in OPENSSLDIR (see the output of <a href="../man1/openssl-version.html">openssl-version(1)</a>). This can be overridden using an environment variable named <b>CTLOG_FILE</b>. 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> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man7/ct.html">ct(7)</a>, <a href="../man3/CTLOG_STORE_get0_log_by_id.html">CTLOG_STORE_get0_log_by_id(3)</a>, <a href="../man3/SSL_CTX_set_ctlog_list_file.html">SSL_CTX_set_ctlog_list_file(3)</a></p> <h1 id="HISTORY">HISTORY</h1> <p>CTLOG_STORE_new_ex was added in OpenSSL 3.0.
