Use OR of the gnutls_certificate_verify_flags enumerations. .IP "unsigned int * voutput" 12 will hold the certificate verification output. .IP "gnutls_verify_output_function func" 12 If non\-null will be called on each chain element verification with the output. .SH "DESCRIPTION" This function will try to verify the given certificate and return its status. The \fIverify\fP parameter will hold an OR'ed sequence of \fBgnutls_certificate_status_t\fP flags. Additionally a certificate verification profile can be specified from the ones in \fBgnutls_certificate_verification_profiles_t\fP by ORing the result of \fBGNUTLS_PROFILE_TO_VFLAGS()\fP to the verification flags. The acceptable \fIdata\fP types are \fBGNUTLS_DT_DNS_HOSTNAME\fP and \fBGNUTLS_DT_KEY_PURPOSE_OID\fP. The former accepts as data a null\-terminated hostname, and the latter a null\-terminated object identifier (e.g., \fBGNUTLS_KP_TLS_WWW_SERVER\fP). If a DNS hostname is provided then this function will compare the hostname in the certificate against the given. If names do not match the \fBGNUTLS_CERT_UNEXPECTED_OWNER\fP status flag will be set. If a key purpose OID is provided and the end\-certificate contains the extended key usage PKIX extension, it will be required to be have the provided key purpose or be marked for any purpose, otherwise verification will fail with \fBGNUTLS_CERT_SIGNER_CONSTRAINTS_FAILURE\fP status. .SH "RETURNS" On success, \fBGNUTLS_E_SUCCESS\fP (0) is returned, otherwise a negative error value. Note that verification failure will not result to an error code, only \fIvoutput\fP will be updated. .SH "SINCE" 3.3.8 .SH "REPORTING BUGS" Report bugs to . .br Home page: http://www.gnutls.org .SH COPYRIGHT Copyright \(co 2001-2014 Free Software Foundation, Inc.. .br Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. .SH "SEE ALSO" The full documentation for .B gnutls is maintained as a Texinfo manual.
