+/**
+ * \file mbedtls/config_adjust_psa_from_legacy.h
+ * \brief Adjust PSA configuration: construct PSA configuration from legacy
+ *
+ * When MBEDTLS_PSA_CRYPTO_CONFIG is disabled, we automatically enable
+ * cryptographic mechanisms through the PSA interface when the corresponding
+ * legacy mechanism is enabled. In many cases, this just enables the PSA
+ * wrapper code around the legacy implementation, but we also do this for
+ * some mechanisms where PSA has its own independent implementation so
+ * that high-level modules that can use either cryptographic API have the
+ * same feature set in both cases.

+ * \brief Adjust PSA configuration: automatic enablement from legacy
+ *
+ * To simplify some edge cases, we automatically enable certain cryptographic
+ * mechanisms in the PSA API if they are enabled in the legacy API. The general
+ * idea is that if legacy module M uses mechanism A internally, and A has
+ * both a legacy and a PSA implementation, we enable A through PSA whenever
+ * it's enabled through legacy. This facilitates the transition to PSA
+ * implementations of A for users of M.

- * Uncomment the macro to let mbed TLS use your alternate implementation of

- * platform_util.c.
- *
- * mbedtls_platform_zeroize() is a widely used function across the library to
- * zero a block of memory. The implementation is expected to be secure in the
- * sense that it has been written to prevent the compiler from removing calls
- * to mbedtls_platform_zeroize() as part of redundant code elimination
- * optimizations. However, it is difficult to guarantee that calls to
- * mbedtls_platform_zeroize() will not be optimized by the compiler as older
- * versions of the C language standards do not provide a secure implementation
- * of memset(). Therefore, MBEDTLS_PLATFORM_ZEROIZE_ALT enables users to
- * configure their own implementation of mbedtls_platform_zeroize(), for
- * example by using directives specific to their compiler, features from newer
- * C standards (e.g using memset_s() in C11) or calling a secure memset() from
- * their system (e.g explicit_bzero() in BSD).

- *
- * gmtime() is not a thread-safe function as defined in the C standard. The
- * library will try to use safer implementations of this function, such as
- * gmtime_r() when available. However, if Mbed TLS cannot identify the target
- * system, the implementation of mbedtls_platform_gmtime_r() will default to
- * using the standard gmtime(). In this case, calls from the library to
- * gmtime() will be guarded by the global mutex mbedtls_threading_gmtime_mutex
- * if MBEDTLS_THREADING_C is enabled. We recommend that calls from outside the
- * library are also guarded with this mutex to avoid race conditions. However,
- * if the macro MBEDTLS_PLATFORM_GMTIME_R_ALT is defined, Mbed TLS will
