#define MBEDTLS_CMAC_C

Enable the CMAC (Cipher-based Message Authentication Code) mode for block ciphers.

Note
When #MBEDTLS_CMAC_ALT is active, meaning that the underlying implementation of the CMAC algorithm is provided by an alternate implementation, that alternate implementation may opt to not support AES-192 or 3DES as underlying block ciphers for the CMAC operation.

Module: library/cmac.c

Requires: MBEDTLS_AES_C or MBEDTLS_DES_C

Definition at line 2156 of file mbedtls_config.h.

#define MBEDTLS_CTR_DRBG_C

Enable the CTR_DRBG AES-based random generator. The CTR_DRBG generator uses AES-256 by default. To use AES-128 instead, enable MBEDTLS_CTR_DRBG_USE_128_BIT_KEY above.

Note
To achieve a 256-bit security strength with CTR_DRBG, you must use AES-256 and use sufficient entropy. See ctr_drbg.h for more details.

Module: library/ctr_drbg.c Caller:

Requires: MBEDTLS_AES_C

This module provides the CTR_DRBG AES random number generator.

Definition at line 2176 of file mbedtls_config.h.

Definition at line 2190 of file mbedtls_config.h.

#define MBEDTLS_DES_C

Enable the DES block cipher.

Module: library/des.c Caller: library/pem.c library/cipher.c

PEM_PARSE uses DES/3DES for decrypting encrypted keys.

Warning
DES is considered a weak cipher and its use constitutes a security risk. We recommend considering stronger ciphers instead.

Definition at line 2206 of file mbedtls_config.h.

#define MBEDTLS_DHM_C

Enable the Diffie-Hellman-Merkle module.

Module: library/dhm.c Caller: library/ssl_cli.c library/ssl_srv.c

This module is used by the following key exchanges: DHE-RSA, DHE-PSK

Module: library/sha1.c Caller: library/md.c library/ssl_cli.c library/ssl_srv.c library/ssl_tls.c library/x509write_crt.c

This module is required for TLS 1.2 depending on the handshake parameters, and for SHA1-signed certificates.

Warning
SHA-1 is considered a weak message digest and its use constitutes a security risk. If possible, we recommend avoiding dependencies on it, and considering stronger message digests instead.

Definition at line 2724 of file mbedtls_config.h.

#define MBEDTLS_SHA224_C

Enable the SHA-224 cryptographic hash algorithm.

Requires: MBEDTLS_SHA256_C. The library does not currently support enabling SHA-224 without SHA-256.

#define MBEDTLS_SSL_ALL_ALERT_MESSAGES

Enable sending of alert messages in case of encountered errors as per RFC. If you choose not to send the alert messages, mbed TLS can still communicate with other servers, only debugging of failures is harder.

The advantage of not sending alert messages, is that no information is given about reasons for failures thus preventing adversaries of gaining intel.

Enable sending of all alert messages

Definition at line 1308 of file mbedtls_config.h.

#define MBEDTLS_SSL_ALPN

Enable support for RFC 7301 Application Layer Protocol Negotiation.

Comment this macro to disable support for ALPN.

Module: library/ssl_cache.c Caller:

Requires: MBEDTLS_SSL_CACHE_C

Definition at line 2803 of file mbedtls_config.h.

#define MBEDTLS_SSL_CLI_C

Enable the SSL/TLS client code.

Module: library/ssl_cli.c Caller:

Requires: MBEDTLS_SSL_TLS_C

This module is required for SSL/TLS client support.

Definition at line 2839 of file mbedtls_config.h.

#define MBEDTLS_SSL_CONTEXT_SERIALIZATION

Enable serialization of the TLS context structures, through use of the functions mbedtls_ssl_context_save() and mbedtls_ssl_context_load().

This pair of functions allows one side of a connection to serialize the context associated with the connection, then free or re-use that context while the serialized state is persisted elsewhere, and finally deserialize that state to a live context for resuming read/write operations on the connection. From a protocol perspective, the state of the connection is unaffected, in particular this is entirely transparent to the peer.

Note: this is distinct from TLS session resumption, which is part of the protocol and fully visible by the peer. TLS session resumption enables establishing new connections associated to a saved session with shorter, lighter handshakes, while context serialization is a local optimization in handling a single, potentially long-lived connection.

Enabling these APIs makes some SSL structures larger, as 64 extra bytes are saved after the handshake to allow for more efficient serialization, so if you don't need this feature you'll save RAM by disabling it.

Comment to disable the context serialization APIs.

Definition at line 1374 of file mbedtls_config.h.

#define MBEDTLS_SSL_COOKIE_C

Enable basic implementation of DTLS cookies for hello verification.

Module: library/ssl_cookie.c Caller:

Definition at line 2813 of file mbedtls_config.h.

#define MBEDTLS_SSL_DTLS_ANTI_REPLAY

Enable support for the anti-replay mechanism in DTLS.

Requires: MBEDTLS_SSL_TLS_C MBEDTLS_SSL_PROTO_DTLS

Warning
Disabling this is often a security risk! See mbedtls_ssl_conf_dtls_anti_replay() for details.

Comment this to disable anti-replay in DTLS.

Definition at line 1561 of file mbedtls_config.h.

#define MBEDTLS_SSL_DTLS_CLIENT_PORT_REUSE

Enable server-side support for clients that reconnect from the same port.

Some clients unexpectedly close the connection and try to reconnect using the same source port. This needs special support from the server to handle the new connection securely, as described in section 4.2.8 of RFC 6347. This flag enables that support.

Requires: MBEDTLS_SSL_DTLS_HELLO_VERIFY

Comment this to disable support for clients reusing the source port.

Definition at line 1626 of file mbedtls_config.h.

#define MBEDTLS_SSL_DTLS_HELLO_VERIFY

Enable support for HelloVerifyRequest on DTLS servers.

This feature is highly recommended to prevent DTLS servers being used as amplifiers in DoS attacks against other hosts. It should always be enabled unless you know for sure amplification cannot be a problem in the environment in which your server operates.

Warning
Disabling this can ba a security risk! (see above)

Requires: MBEDTLS_SSL_PROTO_DTLS

Comment this to disable support for HelloVerifyRequest.

Definition at line 1579 of file mbedtls_config.h.

#define MBEDTLS_SSL_DTLS_SRTP

Enable support for negotiation of DTLS-SRTP (RFC 5764) through the use_srtp extension.

Note
This feature provides the minimum functionality required to negotiate the use of DTLS-SRTP and to allow the derivation of the associated SRTP packet protection key material. In particular, the SRTP packet protection itself, as well as the demultiplexing of RTP and DTLS packets at the datagram layer (see Section 5 of RFC 5764), are not handled by this feature. Instead, after successful completion of a handshake negotiating the use of DTLS-SRTP, the extended key exporter API mbedtls_ssl_conf_export_keys_cb() should be used to implement the key exporter described in Section 4.2 of RFC 5764 and RFC 5705 (this is implemented in the SSL example programs). The resulting key should then be passed to an SRTP stack.

Setting this option enables the runtime API mbedtls_ssl_conf_dtls_srtp_protection_profiles() through which the supported DTLS-SRTP protection profiles can be configured. You must call this API at runtime if you wish to negotiate the use of DTLS-SRTP.

Requires: MBEDTLS_SSL_PROTO_DTLS

Uncomment this to enable support for use_srtp extension.

Definition at line 1610 of file mbedtls_config.h.

#define MBEDTLS_SSL_ENCRYPT_THEN_MAC

Enable support for Encrypt-then-MAC, RFC 7366.

This allows peers that both support it to use a more robust protection for ciphersuites using CBC, providing deep resistance against timing attacks on the padding or underlying cipher.

This only affects CBC ciphersuites, and is useless if none is defined.

Requires: MBEDTLS_SSL_PROTO_TLS1_2

Comment this macro to disable support for Encrypt-then-MAC

Definition at line 1406 of file mbedtls_config.h.

#define MBEDTLS_SSL_EXTENDED_MASTER_SECRET

Enable support for RFC 7627: Session Hash and Extended Master Secret Extension.

This was introduced as "the proper fix" to the Triple Handshake familiy of attacks, but it is recommended to always use it (even if you disable renegotiation), since it actually fixes a more fundamental issue in the original SSL/TLS design, and has implications beyond Triple Handshake.

Requires: MBEDTLS_SSL_PROTO_TLS1_2

Comment this macro to disable support for Extended Master Secret.

Definition at line 1422 of file mbedtls_config.h.

#define MBEDTLS_SSL_KEEP_PEER_CERTIFICATE

This option controls the availability of the API mbedtls_ssl_get_peer_cert() giving access to the peer's certificate after completion of the handshake.

Unless you need mbedtls_ssl_peer_cert() in your application, it is recommended to disable this option for reduced RAM usage.

Note
If this option is disabled, mbedtls_ssl_get_peer_cert() is still defined, but always returns NULL.
This option has no influence on the protection against the triple handshake attack. Even if it is disabled, Mbed TLS will still ensure that certificates do not change during renegotiation, for exaple by keeping a hash of the peer's certificate.

Comment this macro to disable storing the peer's certificate after the handshake.

Definition at line 1444 of file mbedtls_config.h.

#define MBEDTLS_SSL_MAX_FRAGMENT_LENGTH

Enable support for RFC 6066 max_fragment_length extension in SSL.

Definition at line 1537 of file mbedtls_config.h.

#define MBEDTLS_SSL_PROTO_TLS1_2

Enable support for TLS 1.2 (and DTLS 1.2 if DTLS is enabled).

Requires: MBEDTLS_SHA1_C or MBEDTLS_SHA256_C or MBEDTLS_SHA512_C (Depends on ciphersuites)

Comment this macro to disable support for TLS 1.2 / DTLS 1.2

Definition at line 1487 of file mbedtls_config.h.

#define MBEDTLS_SSL_RENEGOTIATION

Enable support for TLS renegotiation.

The two main uses of renegotiation are (1) refresh keys on long-lived connections and (2) client authentication after the initial handshake. If you don't need renegotiation, it's probably better to disable it, since it has been associated with security issues in the past and is easy to misuse/misunderstand.

Comment this to disable support for renegotiation.

Note
Even if this option is disabled, both client and server are aware of the Renegotiation Indication Extension (RFC 5746) used to prevent the SSL renegotiation attack (see RFC 5746 Sect. 1). (See mbedtls_ssl_conf_legacy_renegotiation for the configuration of this extension).

Definition at line 1466 of file mbedtls_config.h.

#define MBEDTLS_SSL_SERVER_NAME_INDICATION

Definition at line 1651 of file mbedtls_config.h.

#define MBEDTLS_SSL_SESSION_TICKETS

Enable support for RFC 5077 session tickets in SSL. Client-side, provides full support for session tickets (maintenance of a session store remains the responsibility of the application, though). Server-side, you also need to provide callbacks for writing and parsing tickets, including authenticated encryption and key management. Example callbacks are provided by MBEDTLS_SSL_TICKET_C.

Comment this macro to disable support for SSL session tickets

#define MBEDTLS_TIMING_C

Enable the semi-portable timing interface.

Note
The provided implementation only works on POSIX/Unix (including Linux, BSD and OS X) and Windows. On other platforms, you can either disable that module and provide your own implementations of the callbacks needed by mbedtls_ssl_set_timer_cb() for DTLS, or leave it enabled and provide your own implementation of the whole module by setting MBEDTLS_TIMING_ALT in the current file.
