\&\fBX509_get_subject_name()\fR returns the subject name of certificate \fBx\fR. The
returned value is an internal pointer which \fB\s-1MUST NOT\s0\fR be freed.
.PP
\&\fBX509_set_subject_name()\fR sets the issuer name of certificate \fBx\fR to
\&\fBname\fR. The \fBname\fR parameter is copied internally and should be freed
up when it is no longer needed.
.PP
\&\fBX509_get_issuer_name()\fR and \fBX509_set_issuer_name()\fR are identical to
\&\fBX509_get_subject_name()\fR and \fBX509_set_subject_name()\fR except the get and
