-/*
- * Note: applications that are targeting a specific configuration do not need
- * to use these macros; instead they should directly use the functions they
- * know are available in their configuration.
- *
- * Note: code that is purely based on PSA Crypto (psa_xxx() functions)
- * does not need to use these macros; instead it should use the relevant
- * PSA_WANT_xxx macros.
- *
- * Note: code that is purely based on the legacy crypto APIs (mbedtls_xxx())
- * does not need to use these macros; instead it should use the relevant
- * MBEDTLS_xxx macros.
- *
- * These macros are for code that wants to use <crypto feature> and will do so
- * using <legacy API> or PSA depending on <condition>, where:
- * - <crypto feature> will generally be an algorithm (SHA-256, ECDH) but may
- *   also be a key type (AES, RSA, EC) or domain parameters (elliptic curve);
- * - <legacy API> will be either:
- *      - low-level module API (aes.h, sha256.h), or
- *      - an abstraction layer (md.h, cipher.h);
- * - <condition> will be either:
- *      - depending on what's available in the build:
- *          legacy API used if available, PSA otherwise
- *          (this is done to ensure backwards compatibility); or
- *      - depending on whether MBEDTLS_USE_PSA_CRYPTO is defined.
- *
- * Examples:
- * - TLS 1.2 will compute hashes using either mbedtls_md_xxx() (and
- *   mbedtls_sha256_xxx()) or psa_aead_xxx() depending on whether
- *   MBEDTLS_USE_PSA_CRYPTO is defined;
- * - RSA PKCS#1 v2.1 will compute hashes (for padding) using either
- *   `mbedtls_md()` if it's available, or `psa_hash_compute()` otherwise;
- * - PEM decoding of PEM-encrypted keys will compute MD5 hashes using either
- *   `mbedtls_md5_xxx()` if it's available, or `psa_hash_xxx()` otherwise.
- *
- * Note: the macros are essential to express test dependencies. Inside code,
- * we could instead just use the equivalent pre-processor condition, but
- * that's not possible in test dependencies where we need a single macro.
- * Hopefully, using these macros in code will also help with consistency.
- *
- * The naming scheme for these macros is:
- *      MBEDTLS_HAS_feature_VIA_legacy_OR_PSA(_condition)
- * where:
- * - feature is expressed the same way as in PSA_WANT_xxx macros, for example:
- *   KEY_TYPE_AES, ALG_SHA_256, ECC_SECP_R1_256;
- * - legacy is either LOWLEVEL or the name of the layer: MD, CIPHER;
- * - condition is omitted if it's based on availability, else it's
- *   BASED_ON_USE_PSA.
- *
- * Coming back to the examples above:
- * - TLS 1.2 will determine if it can use SHA-256 using
- *      MBEDTLS_HAS_ALG_SHA_256_VIA_MD_OR_PSA_BASED_ON_USE_PSA
- *   for the purposes of negotiation, and in test dependencies;
- * - RSA PKCS#1 v2.1 tests that used SHA-256 will depend on
- *      MBEDTLS_HAS_ALG_SHA_256_VIA_MD_OR_PSA
- * - PEM decoding code and its associated tests will depend on
- *      MBEDTLS_HAS_ALG_MD5_VIA_LOWLEVEL_OR_PSA
- *
- * Note: every time it's possible to use, say SHA-256, via the MD API, then
- * it's also possible to use it via the low-level API. So, code that wants to
- * use SHA-256 via both APIs only needs to depend on the MD macro. Also, it
- * just so happens that all the code choosing which API to use based on
- * MBEDTLS_USE_PSA_CRYPTO (X.509, TLS 1.2/shared), always uses the abstraction
- * layer (sometimes in addition to the low-level API), so we don't need the
- * MBEDTLS_HAS_feature_VIA_LOWLEVEL_OR_PSA_BASED_ON_USE_PSA macros.
- * (PK, while obeying MBEDTLS_USE_PSA_CRYPTO, doesn't compute hashes itself,
- * even less makes use of ciphers.)
- *
- * Note: the macros MBEDTLS_HAS_feature_VIA_LOWLEVEL_OR_PSA are the minimal
- * condition for being able to use <feature> at all. As such, they should be
- * used for guarding data about <feature>, such as OIDs or size. For example,
- * OID values related to SHA-256 are only useful when SHA-256 can be used at
- * least in some way.
