CTLOG_STORE_new(3)                  OpenSSL                 CTLOG_STORE_new(3)

       CTLOG_STORE_new, CTLOG_STORE_free, CTLOG_STORE_load_default_file,
       CTLOG_STORE_load_file - Create and populate a Certificate Transparency
       log list

       libcrypto, -lcrypto

        #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);

       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() 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 version). 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:


        description = Log 1
        key = <base64-encoded DER SubjectPublicKeyInfo here>

        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 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"

       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

       ct(7), CTLOG_STORE_get0_log_by_id(3), SSL_CTX_set_ctlog_list_file(3)

       These functions were added in OpenSSL 1.1.0.
