/** * \file mbedtls/config_adjust_legacy_crypto.h * \brief Adjust legacy configuration configuration * * This is an internal header. Do not include it directly. * * Automatically enable certain dependencies. Generally, MBEDTLS_xxx * configurations need to be explicitly enabled by the user: enabling * MBEDTLS_xxx_A but not MBEDTLS_xxx_B when A requires B results in a * compilation error. However, we do automatically enable certain options * in some circumstances. One case is if MBEDTLS_xxx_B is an internal option * used to identify parts of a module that are used by other module, and we * don't want to make the symbol MBEDTLS_xxx_B part of the public API. * Another case is if A didn't depend on B in earlier versions, and we * want to use B in A but we need to preserve backward compatibility with * configurations that explicitly activate MBEDTLS_xxx_A but not * MBEDTLS_xxx_B. */ /* * Copyright The Mbed TLS Contributors * SPDX-License-Identifier: Apache-2.0 OR GPL-2.0-or-later */ #ifndef MBEDTLS_CONFIG_ADJUST_LEGACY_CRYPTO_H #define MBEDTLS_CONFIG_ADJUST_LEGACY_CRYPTO_H #if !defined(MBEDTLS_CONFIG_FILES_READ) #error "Do not include mbedtls/config_adjust_*.h manually!
