.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBCTLOG_new_ex()\fR returns a new \s-1CTLOG\s0 that represents the Certificate
Transparency (\s-1CT\s0) log with the given public key and associates it with the
library context \fIlibctx\fR and property query string \fIpropq\fR. A name must also
be provided that can be used to help users identify this log. Ownership of the
public key is transferred.
.PP
\&\fBCTLOG_new()\fR does the same thing as \fBCTLOG_new_ex()\fR but with the default
library context and the default property query string.
.PP
\&\fBCTLOG_new_from_base64_ex()\fR also creates a new \s-1CTLOG,\s0 but takes the
public key in base64\-encoded \s-1DER\s0 form and sets the ct_log pointer to point to
the new \s-1CTLOG.\s0 The base64 will be decoded and the public key parsed. The \s-1CTLOG\s0
will be associated with the given library context \fIlibctx\fR and property query
string \fIpropq\fR.
.PP
\&\fBCTLOG_new_from_base64()\fR does the same thing as
\&\fBCTLOG_new_from_base64_ex()\fR except that the default library context and
property query string are used.
.PP
Regardless of whether \fBCTLOG_new()\fR or \fBCTLOG_new_from_base64()\fR is used, it is the
caller's responsibility to pass the \s-1CTLOG\s0 to \fBCTLOG_free()\fR once it is no longer
needed. This will delete it and, if created by \fBCTLOG_new()\fR, the \s-1EVP_PKEY\s0 that
was passed to it.
.PP
\&\fBCTLOG_get0_name()\fR returns the name of the log, as provided when the \s-1CTLOG\s0 was
created. Ownership of the string remains with the \s-1CTLOG.\s0
.PP
\&\fBCTLOG_get0_log_id()\fR sets *log_id to point to a string containing that log's
LogID (see \s-1RFC 6962\s0). It sets *log_id_len to the length of that LogID. For a
v1 \s-1CT\s0 log, the LogID will be a \s-1SHA\-256\s0 hash (i.e. 32 bytes long). Ownership of
the string remains with the \s-1CTLOG.\s0
.PP
\&\fBCTLOG_get0_public_key()\fR returns the public key of the \s-1CT\s0 log. Ownership of the
\&\s-1EVP_PKEY\s0 remains with the \s-1CTLOG.\s0
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBCTLOG_new()\fR will return \s-1NULL\s0 if an error occurs.
.PP
\&\fBCTLOG_new_from_base64()\fR will return 1 on success, 0 otherwise.
