SECTION: Module configuration options

This section allows for the setting of module specific sizes and configuration options. The default values are already present in the relevant header files and should suffice for the regular use cases.

Our advice is to enable options and change their values here only if you have a good reason and know the consequences.

Please check the respective header file for documentation on these parameters (to prevent duplicate documentation).

◆ MBEDTLS_ENTROPY_FORCE_SHA256

#define MBEDTLS_ENTROPY_FORCE_SHA256   /* swyter: ReactOS is primarily 32-bit only, this speeds it up notably */

Force the entropy accumulator to use a SHA-256 accumulator instead of the default SHA-512 based one (if both are available).

Requires: MBEDTLS_SHA256_C

On 32-bit systems SHA-256 can be much faster than SHA-512. Use this option if you have performance concerns.

This option is only useful if both MBEDTLS_SHA256_C and MBEDTLS_SHA512_C are defined. Otherwise the available hash module is used.

Definition at line 1042 of file config.h.

◆ MBEDTLS_ERROR_STRERROR_DUMMY

#define MBEDTLS_ERROR_STRERROR_DUMMY

Enable a dummy error function to make use of mbedtls_strerror() in third party libraries easier when MBEDTLS_ERROR_C is disabled (no effect when MBEDTLS_ERROR_C is enabled).

You can safely disable this if MBEDTLS_ERROR_C is enabled, or if you're not using mbedtls_strerror() or error_strerror() in your application.

Disable if you run into name conflicts and want to really remove the mbedtls_strerror()

Module: library/pkparse.c Caller: library/x509_crt.c library/x509_csr.c

Requires: MBEDTLS_PK_C

Uncomment to enable generic public key parse functions.

Definition at line 2357 of file config.h.

◆ MBEDTLS_PK_PARSE_EC_EXTENDED

#define MBEDTLS_PK_PARSE_EC_EXTENDED

Enhance support for reading EC keys using variants of SEC1 not allowed by RFC 5915 and RFC 5480.

Currently this means parsing the SpecifiedECDomain choice of EC parameters (only known groups are supported, not arbitrary domains, to avoid validation issues).

Disable if you only need to support RFC 5915 + 5480 key formats.

Definition at line 971 of file config.h.

◆ MBEDTLS_PK_RSA_ALT_SUPPORT

#define MBEDTLS_PK_RSA_ALT_SUPPORT

Support external private RSA keys (eg from a HSM) in the PK layer.

◆ MBEDTLS_PLATFORM_C

#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 2435 of file config.h.

◆ MBEDTLS_REMOVE_3DES_CIPHERSUITES

#define MBEDTLS_REMOVE_3DES_CIPHERSUITES

Remove 3DES ciphersuites by default in SSL / TLS. This flag removes the ciphersuites based on 3DES from the default list as returned by mbedtls_ssl_list_ciphersuites(). However, it is still possible to enable (some of) them with mbedtls_ssl_conf_ciphersuites() by including them explicitly.

A man-in-the-browser attacker can recover authentication tokens sent through a TLS connection using a 3DES based cipher suite (see "On the Practical (In-)Security of 64-bit Block Ciphers" by Karthikeyan Bhargavan and Gaƫtan Leurent, see https://sweet32.info/SWEET32_CCS16.pdf). If this attack falls in your threat model or you are unsure, then you should keep this option enabled to remove 3DES based cipher suites.

Comment this macro to keep 3DES in the default ciphersuite list.

Definition at line 614 of file config.h.

◆ MBEDTLS_REMOVE_ARC4_CIPHERSUITES

#define MBEDTLS_REMOVE_ARC4_CIPHERSUITES

Remove RC4 ciphersuites by default in SSL / TLS. This flag removes the ciphersuites based on RC4 from the default list as returned by mbedtls_ssl_list_ciphersuites(). However, it is still possible to enable (some of) them with mbedtls_ssl_conf_ciphersuites() by including them explicitly.

Uncomment this macro to remove RC4 ciphersuites by default.

Definition at line 594 of file config.h.

◆ MBEDTLS_RIPEMD160_C

◆ MBEDTLS_SHA1_C

#define MBEDTLS_SHA1_C

Enable the SHA1 cryptographic hash algorithm.

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 SSL/TLS up to version 1.1, 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 2487 of file config.h.

◆ MBEDTLS_SHA256_C

#define MBEDTLS_SHA256_C

Enable the SHA-224 and SHA-256 cryptographic hash algorithms.

Module: library/sha512.c Caller: library/entropy.c library/md.c library/ssl_cli.c library/ssl_srv.c

This module adds support for SHA-384 and SHA-512.

Definition at line 2519 of file config.h.

◆ MBEDTLS_SSL_ALL_ALERT_MESSAGES

#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 1174 of file config.h.

◆ MBEDTLS_SSL_ALPN

#define MBEDTLS_SSL_ALPN

Enable support for RFC 7301 Application Layer Protocol Negotiation.

◆ MBEDTLS_SSL_CBC_RECORD_SPLITTING

#define MBEDTLS_SSL_CBC_RECORD_SPLITTING

Enable 1/n-1 record splitting for CBC mode in SSLv3 and TLS 1.0.

This is a countermeasure to the BEAST attack, which also minimizes the risk of interoperability issues compared to sending 0-length records.

Comment this macro to disable 1/n-1 record splitting.

Definition at line 1265 of file config.h.

◆ MBEDTLS_SSL_CLI_C

#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 2567 of file config.h.

◆ MBEDTLS_SSL_ENCRYPT_THEN_MAC

#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 1208 of file config.h.

◆ MBEDTLS_SSL_EXTENDED_MASTER_SECRET

#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 1226 of file config.h.

Definition at line 1352 of file config.h.

◆ MBEDTLS_SSL_PROTO_TLS1_2

#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 1364 of file config.h.

◆ MBEDTLS_SSL_RENEGOTIATION

#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 1287 of file config.h.

◆ MBEDTLS_SSL_SERVER_NAME_INDICATION

#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 1483 of file config.h.

◆ MBEDTLS_SSL_SESSION_TICKETS

#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

Definition at line 1462 of file config.h.

This module is required for SSL/TLS.

Definition at line 2597 of file config.h.

◆ MBEDTLS_SSL_TRUNCATED_HMAC

#define MBEDTLS_SSL_TRUNCATED_HMAC

Enable support for RFC 6066 truncated HMAC in SSL.

Comment this macro to disable support for truncated HMAC in SSL

Definition at line 1492 of file config.h.

◆ MBEDTLS_TIMING_C

#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.

◆ MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_KEY_EXCHANGE

#define MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_KEY_EXCHANGE

Complete list of ciphersuites to use, in order of preference.

Warning
No dependency checking is done on that field! This option can only be used to restrict the set of available ciphersuites. It is your responsibility to make sure the needed modules are active.

Use this to save a few hundred bytes of ROM (default ordering of all available ciphersuites) and a few to a few hundred bytes of RAM.

The value below is only an example, not the default.Allow SHA-1 in the default TLS configuration for certificate signing. Without this build-time option, SHA-1 support must be activated explicitly through mbedtls_ssl_conf_cert_profile. Turning on this option is not recommended because of it is possible to generate SHA-1 collisions, however this may be safe for legacy infrastructure where additional controls apply.

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.Allow SHA-1 in the default TLS configuration for TLS 1.2 handshake signature and ciphersuite selection. Without this build-time option, SHA-1 support must be activated explicitly through mbedtls_ssl_conf_sig_hashes. The use of SHA-1 in TLS <= 1.1 and in HMAC-SHA-1 is always allowed by default. At the time of writing, there is no practical attack on the use of SHA-1 in handshake signatures, hence this option is turned on by default to preserve compatibility with existing peers, but the general warning applies nonetheless:
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.

◆ MBEDTLS_X509_CHECK_EXTENDED_KEY_USAGE

#define MBEDTLS_X509_CHECK_EXTENDED_KEY_USAGE

Enable verification of the extendedKeyUsage extension (leaf certificates).

Disabling this avoids problems with mis-issued and/or misused certificates.

Warning
Depending on your PKI use, disabling this can be a security risk!

Comment to skip extendedKeyUsage checking for certificates.

Definition at line 1600 of file config.h.

◆ MBEDTLS_X509_CHECK_KEY_USAGE

#define MBEDTLS_X509_CHECK_KEY_USAGE

Enable verification of the keyUsage extension (CA and leaf certificates).

Disabling this avoids problems with mis-issued and/or misused (intermediate) CA and leaf certificates.

Warning
Depending on your PKI use, disabling this can be a security risk!

Comment to skip keyUsage checking for both CA and leaf certificates.
