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 overridden
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. The former accepts as data a null-termi‐
nated hostname, and the latter a null-terminated object identifier
(e.g., GNUTLS_KP_TLS_WWW_SERVER). If a DNS hostname is provided then
this function will compare the hostname in the certificate against the
given. If names do not match the GNUTLS_CERT_UNEXPECTED_OWNER status
flag will be set. If a key purpose OID is provided and the end-cer‐
tificate contains the extended key usage PKIX extension, it will be
required to be have the provided key purpose or be marked for any pur‐
pose, otherwise verification will fail with GNUTLS_CERT_SIGNER_CON‐
STRAINTS_FAILURE status.
RETURNS
a negative error code on error and GNUTLS_E_SUCCESS (0) on success.
