+ * \def MBEDTLS_AES_ALT
+ *
+ * MBEDTLS__MODULE_NAME__ALT: Uncomment a macro to let Mbed TLS use your
+ * alternate core implementation of a symmetric crypto, an arithmetic or hash
+ * module (e.g. platform specific assembly optimized implementations). Keep
+ * in mind that the function prototypes should remain the same.
+ *
+ * This replaces the whole module. If you only want to replace one of the
+ * functions, use one of the MBEDTLS__FUNCTION_NAME__ALT flags.
+ *
+ * Example: In case you uncomment MBEDTLS_AES_ALT, Mbed TLS will no longer
+ * provide the "struct mbedtls_aes_context" definition and omit the base
+ * function declarations and implementations. "aes_alt.h" will be included from
+ * "aes.h" to include the new function definitions.
+ *
+ * Uncomment a macro to enable alternate implementation of the corresponding
+ * module.
+ *
+ * \warning   MD2, MD4, MD5, ARC4, DES and SHA-1 are considered weak and their
+ *            use constitutes a security risk. If possible, we recommend
+ *            avoiding dependencies on them, and considering stronger message
+ *            digests and ciphers instead.
