gnutls_certificate_verify_peers2(3) gnutls gnutls_certificate_verify_peers2(3) 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 of gnutls_certificate_status_t values or zero if the certificate is trusted. Note that value in sta- tus 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_ver- ify_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. RETURNS 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. REPORTING BUGS Report bugs to <bugs@gnutls.org>.
