155 .IX Header "DESCRIPTION"
156 \&\fISSL_get_verify_result()\fR returns the result of the verification of the
157 X509 certificate presented by the peer, if any.
158 .SH "NOTES"
159 .IX Header "NOTES"
160 \&\fISSL_get_verify_result()\fR can only return one error code while the verification
161 of a certificate can fail because of many reasons at the same time. Only
162 the last verification error that occurred during the processing is available
163 from \fISSL_get_verify_result()\fR.

165 The verification result is part of the established session and is restored
166 when a session is reused.
167 .SH "BUGS"
168 .IX Header "BUGS"
169 If no peer certificate was presented, the returned result code is
170 X509_V_OK. This is because no verification error occurred, it does however
171 not indicate success. \fISSL_get_verify_result()\fR is only useful in connection
172 with \fISSL_get_peer_certificate\fR\|(3).
