Since 3.6.4. * @GNUTLS_ENABLE_EARLY_DATA: Under TLS1.3 allow the server to receive early data sent as part of the initial ClientHello (0-RTT). * This can also be used to explicitly indicate that the client will send early data. * This is not enabled by default as early data has weaker security properties than other data. Since 3.6.5. * @GNUTLS_FORCE_CLIENT_CERT: When in client side and only a single cert is specified, send that certificate irrespective of the issuers expected by the server. Since 3.5.0. * @GNUTLS_NO_TICKETS: Flag to indicate that the session should not use resumption with session tickets. * @GNUTLS_KEY_SHARE_TOP3: Generate key shares for the top-3 different groups which are enabled. * That is, as each group is associated with a key type (EC, finite field, x25519), generate * three keys using %GNUTLS_PK_DH, %GNUTLS_PK_EC, %GNUTLS_PK_ECDH_X25519 if all of them are enabled. * @GNUTLS_KEY_SHARE_TOP2: Generate key shares for the top-2 different groups which are enabled. * For example (ECDH + x25519). This is the default. * @GNUTLS_KEY_SHARE_TOP: Generate key share for the first group which is enabled. * For example x25519. This option is the most performant for client (less CPU spent * generating keys), but if the server doesn't support the advertized option it may * result to more roundtrips needed to discover the server's choice. * @GNUTLS_NO_AUTO_REKEY: Disable auto-rekeying under TLS1.3. If this option is not specified * gnutls will force a rekey after 2^24 records have been sent. * @GNUTLS_POST_HANDSHAKE_AUTH: Enable post handshake authentication for server and client. When set and * a server requests authentication after handshake %GNUTLS_E_REAUTH_REQUEST will be returned * by gnutls_record_recv(). A client should then call gnutls_reauth() to re-authenticate. * @GNUTLS_SAFE_PADDING_CHECK: Flag to indicate that the TLS 1.3 padding check will be done in a * safe way which doesn't leak the pad size based on GnuTLS processing time. This is of use to * applications which hide the length of transferred data via the TLS1.3 padding mechanism and * are already taking steps to hide the data processing time. This comes at a performance * penalty. * @GNUTLS_AUTO_REAUTH: Enable transparent re-authentication in client side when the server * requests to. That is, reauthentication is handled within gnutls_record_recv(), and * the %GNUTLS_E_REHANDSHAKE or %GNUTLS_E_REAUTH_REQUEST are not returned. This must be * enabled with %GNUTLS_POST_HANDSHAKE_AUTH for TLS1.3. Enabling this flag requires to restore * interrupted calls to gnutls_record_recv() based on the output of gnutls_record_get_direction(), * since gnutls_record_recv() could be interrupted when sending when this flag is enabled. * Note this flag may not be used if you are using the same session for sending and receiving * in different threads. * @GNUTLS_ENABLE_RAWPK: Allows raw public-keys to be negotiated during the handshake. Since 3.6.6. * @GNUTLS_NO_AUTO_SEND_TICKET: Under TLS1.3 disable auto-sending of * session tickets during the handshake. * @GNUTLS_NO_END_OF_EARLY_DATA: Under TLS1.3 suppress sending EndOfEarlyData message. Since 3.7.2. * * Enumeration of different flags for gnutls_init() function. All the flags * can be combined except @GNUTLS_SERVER and @GNUTLS_CLIENT which are mutually * exclusive. * * The key share options relate to the TLS 1.3 key share extension * which is a speculative key generation expecting that the server * would support the generated key. */ typedef enum { GNUTLS_SERVER = 1, GNUTLS_CLIENT = (1<<1), GNUTLS_DATAGRAM = (1<<2), GNUTLS_NONBLOCK = (1<<3), GNUTLS_NO_EXTENSIONS = (1<<4), GNUTLS_NO_REPLAY_PROTECTION = (1<<5), GNUTLS_NO_SIGNAL = (1<<6), GNUTLS_ALLOW_ID_CHANGE = (1<<7), GNUTLS_ENABLE_FALSE_START = (1<<8), GNUTLS_FORCE_CLIENT_CERT = (1<<9), GNUTLS_NO_TICKETS = (1<<10), GNUTLS_KEY_SHARE_TOP = (1<<11), GNUTLS_KEY_SHARE_TOP2 = (1<<12), GNUTLS_KEY_SHARE_TOP3 = (1<<13), GNUTLS_POST_HANDSHAKE_AUTH = (1<<14), GNUTLS_NO_AUTO_REKEY = (1<<15), GNUTLS_SAFE_PADDING_CHECK = (1<<16), GNUTLS_ENABLE_EARLY_START = (1<<17), GNUTLS_ENABLE_RAWPK = (1<<18), GNUTLS_AUTO_REAUTH = (1<<19), GNUTLS_ENABLE_EARLY_DATA = (1<<20), GNUTLS_NO_AUTO_SEND_TICKET = (1<<21), GNUTLS_NO_END_OF_EARLY_DATA = (1<<22) } gnutls_init_flags_t;
