+ * @GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE: Make a signature on the hashed data with reproducible parameters.
+ *   For RSA-PSS, that means to use empty salt instead of random value. To

+ * @GNUTLS_PRIVKEY_IMPORT_COPY: Copy required values during import.
+ * @GNUTLS_PRIVKEY_DISABLE_CALLBACKS: The following flag disables call to PIN callbacks etc.
+ *   Only relevant to TPM keys.

+ * @GNUTLS_PRIVKEY_FLAG_CA: The generated private key is going to be used as a CA (relevant for RSA-PSS keys).
+ * @GNUTLS_PRIVKEY_FLAG_EXPORT_COMPAT: Keys generated or imported as provable require an extended format which cannot be read by previous versions
+ *   of gnutls or other applications. By setting this flag the key will be exported in a backwards compatible way,
+ *   even if the information about the seed used will be lost.
+ * @GNUTLS_PRIVKEY_FLAG_RSA_PSS_FIXED_SALT_LENGTH: When making an RSA-PSS
+ *   signature, use the salt whose length is equal to the digest length, as
+ *   mandated in RFC 8446 4.2.3.

+ * gnutls_init_flags_t:
+ *
+ * @GNUTLS_SERVER: Connection end is a server.
+ * @GNUTLS_CLIENT: Connection end is a client.
+ * @GNUTLS_DATAGRAM: Connection is datagram oriented (DTLS). Since 3.0.0.
+ * @GNUTLS_NONBLOCK: Connection should not block. Since 3.0.0.
+ * @GNUTLS_NO_SIGNAL: In systems where SIGPIPE is delivered on send, it will be disabled. That flag has effect in systems which support the MSG_NOSIGNAL sockets flag (since 3.4.2).
+ * @GNUTLS_NO_EXTENSIONS: Do not enable any TLS extensions by default (since 3.1.2). As TLS 1.2 and later require extensions this option is considered obsolete and should not be used.
+ * @GNUTLS_NO_REPLAY_PROTECTION: Disable any replay protection in DTLS. This must only be used if  replay protection is achieved using other means. Since 3.2.2.
+ * @GNUTLS_ALLOW_ID_CHANGE: Allow the peer to replace its certificate, or change its ID during a rehandshake. This change is often used in attacks and thus prohibited by default. Since 3.5.0.
+ * @GNUTLS_ENABLE_FALSE_START: Enable the TLS false start on client side if the negotiated ciphersuites allow it. This will enable sending data prior to the handshake being complete, and may introduce a risk of crypto failure when combined with certain key exchanged; for that GnuTLS may not enable that option in ciphersuites that are known to be not safe for false start. Since 3.5.0.
+ * @GNUTLS_ENABLE_EARLY_START: Under TLS1.3 allow the server to return earlier than the full handshake
+ *   finish; similarly to false start the handshake will be completed once data are received by the
+ *   client, while the server is able to transmit sooner. This is not enabled by default as it could
+ *   break certain existing server assumptions and use-cases. 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_NO_TICKETS_TLS12: Flag to indicate that the session should not use resumption with session tickets. This flag only has effect if TLS 1.2 is used.
+ * @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

+ * @GNUTLS_VERIFY_DO_NOT_ALLOW_SAME: If a certificate is not signed by

+ *   as trusted.
+ * @GNUTLS_VERIFY_ALLOW_UNSORTED_CHAIN: A certificate chain is tolerated
+ *   if unsorted (the case with many TLS servers out there). This is the
+ *   default since GnuTLS 3.1.4.
+ * @GNUTLS_VERIFY_DO_NOT_ALLOW_UNSORTED_CHAIN: Do not tolerate an unsorted

+ * @GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT: Allow CA certificates that

+ * @GNUTLS_VERIFY_DISABLE_CRL_CHECKS: Disable checking for validity
+ *   using certificate revocation lists or the available OCSP data.
+ * @GNUTLS_VERIFY_DO_NOT_ALLOW_WILDCARDS: When including a hostname
+ *   check in the verification, do not consider any wildcards.
+ * @GNUTLS_VERIFY_DO_NOT_ALLOW_IP_MATCHES: When verifying a hostname
+ *   prevent textual IP addresses from matching IP addresses in the
+ *   certificate. Treat the input only as a DNS name.
+ * @GNUTLS_VERIFY_USE_TLS1_RSA: This indicates that a (raw) RSA signature is provided
+ *   as in the TLS 1.0 protocol. Not all functions accept this flag.
+ * @GNUTLS_VERIFY_IGNORE_UNKNOWN_CRIT_EXTENSIONS: This signals the verification
+ *   process, not to fail on unknown critical extensions.
+ * @GNUTLS_VERIFY_RSA_PSS_FIXED_SALT_LENGTH: Disallow RSA-PSS signatures made
