Имя (Name)
gnutls_certificate_verify_peers2 - API function
Синопсис (Synopsis)
#include <gnutls/gnutls.h>
int gnutls_certificate_verify_peers2(gnutls_session_t session,
unsigned int * status);
Аргументы (Arguments)
gnutls_session_t session
is a gnutls session
unsigned int * status
is the output of the verification
Описание (Description)
This function will verify the peer's certificate and store the
status in the status variable as a bitwise OR of
gnutls_certificate_status_t values or zero if the certificate is
trusted. Note that value in status is set only when the return
value of this function is success (i.e, failure to trust a
certificate does not imply a negative return value). The default
verification flags used by this function can be overridden using
gnutls_certificate_set_verify_flags().
This function will take into account the stapled OCSP responses
sent by the server, as well as the following X.509 certificate
extensions: Name Constraints, Key Usage, and Basic Constraints
(pathlen).
Note that you must also check the peer's name in order to check
if the verified certificate belongs to the actual peer, see
gnutls_x509_crt_check_hostname(), or use
gnutls_certificate_verify_peers3().
To avoid denial of service attacks some default upper limits
regarding the certificate key size and chain size are set. To
override them use gnutls_certificate_set_verify_limits().
Note that when using raw public-keys verification will not work
because there is no corresponding certificate body belonging to
the raw key that can be verified. In that case this function will
return GNUTLS_E_INVALID_REQUEST.
Возвращаемое значение (Return value)
GNUTLS_E_SUCCESS (0) when the validation is performed, or a
negative error code otherwise. A successful error code means
that the status parameter must be checked to obtain the
validation status.
