.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
A \s-1CTLOG_STORE\s0 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 \s-1RFC\s0 6962, Section 3.2, for the definition of a LogID).
.PP
\&\fICTLOG_STORE_new()\fR creates an empty list of \s-1CT\s0 logs. This is then populated
by \fICTLOG_STORE_load_default_file()\fR or \fICTLOG_STORE_load_file()\fR.
\&\fICTLOG_STORE_load_default_file()\fR loads from the default file, which is named
\&\fIct_log_list.cnf\fR in \s-1OPENSSLDIR\s0 (see the output of \fIopenssl\-version\fR\|(1)).
This can be overridden using an environment variable named \fB\s-1CTLOG_FILE\s0\fR.
\&\fICTLOG_STORE_load_file()\fR loads from a caller-specified file path instead.
Both of these functions append any loaded \s-1CT\s0 logs to the \s-1CTLOG_STORE\s0.
.PP
The expected format of the file is:
.PP
.Vb 1
\& enabled_logs=foo,bar
\&
\& [foo]
\& description = Log 1
\& key = <base64\-encoded DER SubjectPublicKeyInfo here>
\&
\& [bar]
\& description = Log 2
\& key = <base64\-encoded DER SubjectPublicKeyInfo here>
.Ve
.PP
Once a \s-1CTLOG_STORE\s0 is no longer required, it should be passed to
\&\fICTLOG_STORE_free()\fR. This will delete all of the CTLOGs stored within, along
with the \s-1CTLOG_STORE\s0 itself.
.SH "NOTES"
.IX Header "NOTES"
If there are any invalid \s-1CT\s0 logs in a file, they are skipped and the remaining
valid logs will still be added to the \s-1CTLOG_STORE\s0. A \s-1CT\s0 log will be considered
invalid if it is missing a \*(L"key\*(R" or \*(L"description\*(R" field.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
Both \fBCTLOG_STORE_load_default_file\fR and \fBCTLOG_STORE_load_file\fR return 1 if
all \s-1CT\s0 logs in the file are successfully parsed and loaded, 0 otherwise.
