/**
* \def 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 Gaëtan
* 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.
