gnutls_x509_crt_check_hostname2 - API function
Синопсис (Synopsis)
#include <gnutls/x509.h>
unsigned gnutls_x509_crt_check_hostname2(gnutls_x509_crt_t cert,
const char * hostname, unsigned int flags);
Аргументы (Arguments)
gnutls_x509_crt_t cert
should contain an gnutls_x509_crt_t type
const char * hostname
A null terminated string that contains a DNS name
unsigned int flags
gnutls_certificate_verify_flags
Описание (Description)
This function will check if the given certificate's subject
matches the given hostname. This is a basic implementation of
the matching described in RFC6125, and takes into account
wildcards, and the DNSName/IPAddress subject alternative name
PKIX extension.
IPv4 addresses are accepted by this function in the
dotted-decimal format (e.g, ddd.ddd.ddd.ddd), and IPv6 addresses
in the hexadecimal x:x:x:x:x:x:x:x format. For them the IPAddress
subject alternative name extension is consulted. Previous
versions to 3.6.0 of GnuTLS in case of a non-match would consult
(in a non-standard extension) the DNSname and CN fields. This is
no longer the case.
When the flag GNUTLS_VERIFY_DO_NOT_ALLOW_WILDCARDS is specified
no wildcards are considered. Otherwise they are only considered
if the domain name consists of three components or more, and the
wildcard starts at the leftmost position. When the flag
GNUTLS_VERIFY_DO_NOT_ALLOW_IP_MATCHES is specified, the input
will be treated as a DNS name, and matching of textual IP
addresses against the IPAddress part of the alternative name will
not be allowed.
The function gnutls_x509_crt_check_ip() is available for matching
IP addresses.
Возвращаемое значение (Return value)
non-zero for a successful match, and zero on failure.
