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
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.
The acceptable
data types are
GNUTLS_DT_DNS_HOSTNAME and
GNUTLS_DT_KEY_PURPOSE_OID. The former accepts as data a null-terminated
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-certificate contains the
extended key usage PKIX extension, it will be required to be have the provided
key purpose 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.
