SSL_CTX_set_ctlog_list_file.3ossl - Man Page

load a Certificate Transparency log list from a file

Synopsis

 #include <openssl/ssl.h>

 int SSL_CTX_set_default_ctlog_list_file(SSL_CTX *ctx);
 int SSL_CTX_set_ctlog_list_file(SSL_CTX *ctx, const char *path);

Description

SSL_CTX_set_default_ctlog_list_file() loads a list of Certificate Transparency (CT) logs from the default file location, “ct_log_list.cnf”, found in the directory where OpenSSL is installed.

SSL_CTX_set_ctlog_list_file() loads a list of CT logs from a specific path. See CTLOG_STORE_new(3) for the file format.

Notes

These functions will not clear the existing CT log list - it will be appended to. To replace the existing list, use SSL_CTX_set0_ctlog_store(3) first.

If an error occurs whilst parsing a particular log entry in the file, that log entry will be skipped.

Return Values

SSL_CTX_set_default_ctlog_list_file() and SSL_CTX_set_ctlog_list_file() return 1 if the log list is successfully loaded, and 0 if an error occurs. In the case of an error, the log list may have been partially loaded.
