## Macro Definition Documentation

#define MBEDTLS_AES_ALT

MBEDTLS__MODULE_NAME__ALT: Uncomment a macro to let mbed TLS use your alternate core implementation of a symmetric crypto or hash module (e.g.

platform specific assembly optimized implementations). Keep in mind that the function prototypes should remain the same.

This replaces the whole module. If you only want to replace one of the functions, use one of the MBEDTLS__FUNCTION_NAME__ALT flags.

Example: In case you uncomment MBEDTLS_AES_ALT, mbed TLS will no longer provide the "struct mbedtls_aes_context" definition and omit the base function declarations and implementations. "aes_alt.h" will be included from "aes.h" to include the new function definitions.

Uncomment a macro to enable alternate implementation of the corresponding module.

#define MBEDTLS_MD2_PROCESS_ALT

MBEDTLS__FUNCTION_NAME__ALT: Uncomment a macro to let mbed TLS use you alternate core implementation of symmetric crypto or hash function.

Keep in mind that function prototypes should remain the same.

This replaces only one function. The header file from mbed TLS is still used, in contrast to the MBEDTLS__MODULE_NAME__ALT flags.

Example: In case you uncomment MBEDTLS_SHA256_PROCESS_ALT, mbed TLS will no longer provide the mbedtls_sha1_process() function, but it will still provide the other function (using your mbedtls_sha1_process() function) and the definition of mbedtls_sha1_context, so your implementation of mbedtls_sha1_process must be compatible with this definition.

Note: if you use the AES_xxx_ALT macros, then is is recommended to also set MBEDTLS_AES_ROM_TABLES in order to help the linker garbage-collect the AES tables.

#define MBEDTLS_PLATFORM_C

Enable the platform abstraction layer that allows you to re-assign functions like calloc(), free(), snprintf(), printf(), fprintf(), exit().

Enabling MBEDTLS_PLATFORM_C enables to use of MBEDTLS_PLATFORM_XXX_ALT or MBEDTLS_PLATFORM_XXX_MACRO directives, allowing the functions mentioned above to be specified at runtime or compile time respectively.

Note
  This abstraction layer must be enabled on Windows (including MSYS2) as other module rely on it for a fixed snprintf implementation.

Module: library/platform.c Caller: Most other .c files

This module enables abstraction of common (libc) functions.

Definition at line 2086 of file config.h.

#define MBEDTLS_PLATFORM_EXIT_ALT

MBEDTLS_PLATFORM_XXX_ALT: Uncomment a macro to let mbed TLS support the function in the platform abstraction layer.

Example: In case you uncomment MBEDTLS_PLATFORM_PRINTF_ALT, mbed TLS will provide a function "mbedtls_platform_set_printf()" that allows you to set an alternative printf function pointer.

All these define require MBEDTLS_PLATFORM_C to be defined!

Note
  MBEDTLS_PLATFORM_SNPRINTF_ALT is required on Windows; it will be enabled automatically by check_config.h

#define MBEDTLS_PLATFORM_MEMORY

Enable the memory allocation layer.

By default mbed TLS uses the system-provided calloc() and free(). This allows different allocators (self-implemented or provided) to be provided to the platform abstraction layer.

Enabling MBEDTLS_PLATFORM_MEMORY without the MBEDTLS_PLATFORM_{FREE,CALLOC}_MACROs will provide "mbedtls_platform_set_calloc_free()" allowing you to set an alternative calloc() and free() function pointer at runtime.

Enabling MBEDTLS_PLATFORM_MEMORY and specifying MBEDTLS_PLATFORM_{CALLOC,FREE}_MACROs will allow you to specify the alternate function at compile time.

Requires: MBEDTLS_PLATFORM_C

Enable this layer to allow use of alternative memory allocators.

#define MBEDTLS_PLATFORM_NO_STD_FUNCTIONS

Do not assign standard functions in the platform layer (e.g.

calloc() to MBEDTLS_PLATFORM_STD_CALLOC and printf() to MBEDTLS_PLATFORM_STD_PRINTF)

This makes sure there are no linking errors on platforms that do not support these functions. You will HAVE to provide alternatives, either at runtime via the platform_set_xxx() functions or at compile time by setting the MBEDTLS_PLATFORM_STD_XXX defines, or enabling a MBEDTLS_PLATFORM_XXX_MACRO.

#define MBEDTLS_SHA256_SMALLER

Enable an implementation of SHA-256 that has lower ROM footprint but also lower performance.

The default implementation is meant to be a reasonnable compromise between performance and size. This version optimizes more aggressively for size at the expense of performance. Eg on Cortex-M4 it reduces the size of mbedtls_sha256_process() from ~2KB to ~0.5KB for a performance hit of about 30%.

Definition at line 900 of file config.h.

#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

#define MBEDTLS_SSL_DEBUG_ALL

Enable the debug messages in SSL module for all issues.

Debug messages have been disabled in some places to prevent timing attacks due to (unbalanced) debugging function calls.

If you need all error reporting you should enable this during debugging, but remove this for production servers that should log as well.

Uncomment this macro to report all debug messages on errors introducing a timing side-channel.

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

Definition at line 1170 of file 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 1154 of file 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 or MBEDTLS_SSL_PROTO_TLS1_1 or MBEDTLS_SSL_PROTO_TLS1_2

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

Definition at line 948 of file config.h.

#define MBEDTLS_SSL_EXPORT_KEYS

Enable support for exporting key block and master secret.

This is required for certain users of TLS, e.g. EAP-TLS.

Comment this macro to disable support for key export

Definition at line 1205 of file config.h.

#define MBEDTLS_SSL_EXTENDED_MASTER_SECRET

Enable support for Extended Master Secret, aka Session Hash (draft-ietf-tls-session-hash-02).

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 or MBEDTLS_SSL_PROTO_TLS1_1 or MBEDTLS_SSL_PROTO_TLS1_2

Comment this macro to disable support for Extended Master Secret.

Definition at line 966 of file config.h.

#define MBEDTLS_SSL_FALLBACK_SCSV

Enable support for FALLBACK_SCSV (draft-ietf-tls-downgrade-scsv-00).

For servers, it is recommended to always enable this, unless you support only one version of TLS, or know for sure that none of your clients implements a fallback strategy.

For clients, you only need this if you're using a fallback strategy, which is not recommended in the first place, unless you absolutely need it to interoperate with buggy (version-intolerant) servers.

Comment this macro to disable support for FALLBACK_SCSV

Definition at line 983 of file config.h.

#define MBEDTLS_SSL_HW_RECORD_ACCEL

Enable hooking functions in SSL module for hardware acceleration of individual records.

Uncomment this macro to enable hooking functions.

Definition at line 993 of file config.h.

Definition at line 1085 of file 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 1097 of file config.h.

#define MBEDTLS_SSL_RENEGOTIATION

Disable 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.

Definition at line 1020 of file config.h.

#define MBEDTLS_SSL_SERVER_NAME_INDICATION

Enable support for RFC 6066 server name indication (SNI) in SSL.

Requires: MBEDTLS_X509_CRT_PARSE_C

Comment this macro to disable support for server name indication in SSL

Definition at line 1216 of file config.h.

#define MBEDTLS_SSL_SESSION_TICKETS

Enable support for RFC 5077 session tickets in SSL.

Client-side, provides full support for session tickets (maintainance 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

Definition at line 1195 of file config.h.

Requires: MBEDTLS_THREADING_C

Uncomment this to allow your own alternate threading implementation.

Definition at line 1236 of file config.h.

#define MBEDTLS_THREADING_C

Enable the threading abstraction layer.

By default mbed TLS assumes it is used in a non-threaded environment or that contexts are not shared between threads. If you do intend to use contexts between threads, you will need to enable this layer to prevent race conditions.

Module: library/threading.c

This allows different threading implementations (self-implemented or provided).

You will have to enable either MBEDTLS_THREADING_ALT or MBEDTLS_THREADING_PTHREAD.

Enable this layer to allow use of mutexes within mbed TLS
