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 + +/* Auto-enable MBEDTLS_MD_LIGHT based on MBEDTLS_MD_C. + * This allows checking for MD_LIGHT rather than MD_LIGHT || MD_C. + */ +#if defined(MBEDTLS_MD_C) +#define MBEDTLS_MD_LIGHT +#endif + +/* Auto-enable MBEDTLS_MD_LIGHT if needed by a module that didn't require it + * in a previous release, to ensure backwards compatibility. + */ +#if defined(MBEDTLS_ECJPAKE_C) || \ + defined(MBEDTLS_PEM_PARSE_C) || \ + defined(MBEDTLS_ENTROPY_C) || \ + defined(MBEDTLS_PK_C) || \ + defined(MBEDTLS_PKCS12_C) || \ + defined(MBEDTLS_RSA_C) || \ + defined(MBEDTLS_SSL_TLS_C) || \ + defined(MBEDTLS_X509_USE_C) || \ + defined(MBEDTLS_X509_CREATE_C) +#define MBEDTLS_MD_LIGHT +#endif + +/* MBEDTLS_ECP_LIGHT is auto-enabled by the following symbols: + * - MBEDTLS_ECP_C because now it consists of MBEDTLS_ECP_LIGHT plus functions + * for curve arithmetic.
