NAME

gnutls_certificate_verify_peers3 - API function

SYNOPSIS

#include <gnutls/gnutls.h>

int gnutls_certificate_verify_peers3(gnutls_session_t session, const char * hostname, unsigned int * status);

ARGUMENTS

gnutls_session_t session is a gnutls session
const char * hostname is the expected name of the peer; may be NULL
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(). See the documentation of gnutls_certificate_verify_peers2() for details in the verification process.

If the hostname provided is non-NULL then this function will compare the hostname in the certificate against the given. The comparison will be accurate for ascii names; non-ascii names are compared byte-by-byte. If names do not match the GNUTLS_CERT_UNEXPECTED_OWNER status flag will be set.

In order to verify the purpose of the end-certificate (by checking the extended key usage), use gnutls_certificate_verify_peers().

RETURNS

a negative error code on error and GNUTLS_E_SUCCESS (0) when the peer’s certificate was successfully parsed, whether or not it was verified.

SINCE

3.1.4
