gnutls_certificate_verify_peers2 — API function
#include <gnutls/gnutls.h>
int
gnutls_certificate_verify_peers2( |
gnutls_session_t session, |
unsigned int * status); |
is a gnutls session
is the output of the verification
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
overriden 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().
The full documentation for gnutls is maintained as a Texinfo manual. If the /usr/share/doc/gnutls/ directory does not contain the HTML form visit
