|
|
\&\fISSL_get_peer_certificate()\fR returns a pointer to the X509 certificate the
|
|
peer presented. If the peer did not present a certificate, \s-1NULL\s0 is returned.
|
|
.SH "NOTES"
|
|
.IX Header "NOTES"
|
|
That a certificate is returned does not indicate information about the
|
|
verification state, use SSL_get_verify_result(3)
|
|
to check the verification state.
|
|
.PP
|
|
The reference count of the X509 object is incremented by one, so that it
|
|
will not be destroyed when the session containing the peer certificate is
|
|
freed. The X509 object must be explicitly freed using \fIX509_free()\fR.
|
|
.SH "RETURN VALUES"
|
|
.IX Header "RETURN VALUES"
|
|
The following return values can occur:
|
|
.Ip "\s-1NULL\s0" 4
|
|
.IX Item "NULL"
|
|
No certificate was presented by the peer or no connection was established.
|
|
.Ip "Pointer to an X509 certificate" 4
|
|
.IX Item "Pointer to an X509 certificate"
|
|
The return value points to the certificate presented by the peer.
