Typedefs
typedef credman_tag_t(*	sock_dtls_client_psk_cb_t) (sock_dtls_t sock, sock_udp_ep_t ep, credman_tag_t tags[], unsigned tags_len, const char *hint, size_t hint_len)
	Pre-Shared Key client callback.

typedef credman_tag_t(*	sock_dtls_rpk_cb_t) (sock_dtls_t sock, sock_udp_ep_t ep, credman_tag_t tags[], unsigned tags_len)
	Raw Public Key callback.

Functions
int	sock_dtls_set_server_psk_id_hint (sock_dtls_t sock, const char hint)
	Sets the PSK Identity hint to be sent to clients during handshake.

int	sock_dtls_add_credential (sock_dtls_t *sock, credman_tag_t tag)
	Adds a credential tag to list of available credentials for `sock`.

int	sock_dtls_remove_credential (sock_dtls_t *sock, credman_tag_t tag)
	Removes a credential tag of the list of available credentials for `sock`.

size_t	sock_dtls_get_credentials (sock_dtls_t sock, const credman_tag_t *out)
	Returns an array of tags of the registered credentials in `sock`.

void	sock_dtls_set_client_psk_cb (sock_dtls_t *sock, sock_dtls_client_psk_cb_t cb)
	Sets the callback function for clients to specify a credential to use for a given connection.

void	sock_dtls_set_rpk_cb (sock_dtls_t *sock, sock_dtls_rpk_cb_t cb)
	Sets the callback function to specify a credential to use for a given connection, when using Raw Public Keys.

#define	CONFIG_DTLS_PSK_ID_HINT_MAX_SIZE 32
	Default maximum size for the PSK Identity hint string.

#define	CONFIG_DTLS_CREDENTIALS_MAX 4
