NAME
gnutls_certificate_verify_peers - API function
SYNOPSIS
#include <gnutls/gnutls.h>
int gnutls_certificate_verify_peers(gnutls_session_t session,
gnutls_typed_vdata_st * data, unsigned int elements, unsigned int *
status);
ARGUMENTS
gnutls_session_t session
is a gnutls session
gnutls_typed_vdata_st * data
an array of typed data
unsigned int elements
the number of data elements
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 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 overriden
using gnutls_certificate_set_verify_flags(). See the documentation of
gnutls_certificate_verify_peers2() for details in the verification
process.
The acceptable data types are GNUTLS_DT_DNS_HOSTNAME and
GNUTLS_DT_KEY_PURPOSE_OID. If a DNS hostname is provided 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_UNEX‐
PECTED_OWNER status flag will be set.
If a key purpose OID is provided and the end-certificate contains the
extended key usage PKIX extension, it will be required to be have the
provided key purpose (e.g., GNUTLS_KP_TLS_WWW_SERVER), or be marked for
any purpose, otherwise verification will fail with
GNUTLS_CERT_SIGNER_CONSTRAINTS_FAILURE status.
RETURNS
a negative error code on error and GNUTLS_E_SUCCESS (0) on success.

3.3.0
