=pod =head1 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 =head1 SYNOPSIS #include CTLOG_STORE *CTLOG_STORE_new_ex(OPENSSL_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); =head1 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 I and the property query string I. CTLOG_STORE_new() 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 F in OPENSSLDIR (see the output of L). This can be overridden using an environment variable named 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. The expected format of the file is: enabled_logs=foo,bar [foo] description = Log 1 key = [bar] description = Log 2 key = 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. =head1 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. =head1 RETURN VALUES Both B and B return 1 if all CT logs in the file are successfully parsed and loaded, 0 otherwise. =head1 SEE ALSO L, L, L =head1 HISTORY CTLOG_STORE_new_ex was added in OpenSSL 3.0.
