NAME¶
gnutls_certificate_verify_peers2 - API function
SYNOPSIS¶
#include <gnutls/gnutls.h>
int gnutls_certificate_verify_peers2(gnutls_session_t session,
unsigned int * status);
ARGUMENTS¶
- gnutls_session_t session
- is a gnutls session
- unsigned int * status
- is the output of the verification
DESCRIPTION¶
This function will verify the peer's certificate and store the status in the
status variable as a bitwise or'd 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 OCSP Certificate Status TLS extension,
as well as the following X.509 certificate extensions: Name Constraints, Key
Usage, and Basic Constraints (pathlen).
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 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().
RETURNS¶
a negative error code on error and
GNUTLS_E_SUCCESS (0) on success.
