НАЗВАНИЕ

       gnutls_x509_crt_check_hostname2 - API function

СИНТАКСИС

       #include <gnutls/x509.h>

       unsigned gnutls_x509_crt_check_hostname2(gnutls_x509_crt_t cert,
       const char * hostname, unsigned int flags);

АРГУМЕНТЫ

       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

       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.

ЗНАЧЕНИЯ, ВОЗВРАЩАЕМЫЕ ФУНКЦИЕЙ

       non-zero for a successful match, and zero on failure.
