NAME
----
nng_tls_config_auth_mode - configure authentication mode
SYNOPSIS
--------
[source, c]
-----------
#include <nng/nng.h>
typedef enum nng_tls_auth_mode {
NNG_TLS_AUTH_MODE_NONE,
NNG_TLS_AUTH_MODE_OPTIONAL,
NNG_TLS_AUTH_MODE_REQUIRED
} nng_tls_auth_mode;
int nng_tls_config_auth_mode(nni_tls_config *cfg, nng_tls_auth_mode mode);
-----------
DESCRIPTION
-----------
The `nng_tls_config_auth_mode()` function configures the authentication mode
to be used for TLS sessions using this configuration object.
The possible modes are:
`NNG_TLS_AUTH_MODE_NONE`::
No authentication of the TLS peer is performed. This is the default for
TLS servers, which most typically do not authenticate their clients.
`NNG_TLS_AUTH_MODE_OPTIONAL`::
If a certificate is presented by the peer, then it is validated. However,
if the peer does not present a valid certificate, then the sesssion is allowed
to proceed without authentication.
`NNG_TLS_AUTH_MODE_REQUIRED`::
A check is made to ensure that the peer has presented a valid certificate
used for the session. If the peer's certificate is invalid or missing, then
the session is refused. This is the default for clients.
RETURN VALUES
-------------
This function returns 0 on success, and non-zero otherwise.
ERRORS
------
`NNG_ENOMEM`:: Insufficient memory is available.
`NNG_EINVAL`:: An invalid 'mode' was specified.
`NNG_EBUSY`:: The configuration 'cfg' is already in use, and cannot be modified.
