00279  * This configuration option controls whether the library validates more of
00280  * the parameters passed to it.
00281  *
00282  * When this flag is not defined, the library only attempts to validate an
00283  * input parameter if: (1) they may come from the outside world (such as the
00284  * network, the filesystem, etc.) or (2) not validating them could result in
00285  * internal memory errors such as overflowing a buffer controlled by the
00286  * library. On the other hand, it doesn't attempt to validate parameters whose
00287  * values are fully controlled by the application (such as pointers).
00288  *
00289  * When this flag is defined, the library additionally attempts to validate
00290  * parameters that are fully controlled by the application, and should always
00291  * be valid if the application code is fully correct and trusted.
00292  *
00293  * For example, when a function accepts as input a pointer to a buffer that may
00294  * contain untrusted data, and its documentation mentions that this pointer
00295  * must not be NULL:
00296  * - The pointer is checked to be non-NULL only if this option is enabled.
00297  * - The content of the buffer is always validated.
00298  *
00299  * When this flag is defined, if a library function receives a parameter that
00300  * is invalid:
00301  * 1. The function will invoke the macro MBEDTLS_PARAM_FAILED().
00302  * 2. If MBEDTLS_PARAM_FAILED() did not terminate the program, the function
00303  *   will immediately return. If the function returns an Mbed TLS error code,
00304  *   the error code in this case is MBEDTLS_ERR_xxx_BAD_INPUT_DATA.
00305  *
00306  * When defining this flag, you also need to arrange a definition for
00307  * MBEDTLS_PARAM_FAILED(). You can do this by any of the following methods:
00308  * - By default, the library defines MBEDTLS_PARAM_FAILED() to call a
00309  *   function mbedtls_param_failed(), but the library does not define this
00310  *   function. If you do not make any other arrangements, you must provide
00311  *   the function mbedtls_param_failed() in your application.
00312  *   See `platform_util.h` for its prototype.
00313  * - If you enable the macro #MBEDTLS_CHECK_PARAMS_ASSERT, then the
00314  *   library defines MBEDTLS_PARAM_FAILED(\c cond) to be `assert(cond)`.
00315  *   You can still supply an alternative definition of
00316  *   MBEDTLS_PARAM_FAILED(), which may call `assert`.
00317  * - If you define a macro MBEDTLS_PARAM_FAILED() before including `config.h`
00318  *   or you uncomment the definition of MBEDTLS_PARAM_FAILED() in `config.h`,
00319  *   the library will call the macro that you defined and will not supply
00320  *   its own version. Note that if MBEDTLS_PARAM_FAILED() calls `assert`,
00321  *   you need to enable #MBEDTLS_CHECK_PARAMS_ASSERT so that library source
00322  *   files include `<assert.h>`.

00486  * MBEDTLS_ECP__FUNCTION_NAME__ALT: Uncomment a macro to let mbed TLS use your
00487  * alternative core implementation of elliptic curve arithmetic. Keep in mind
00488  * that function prototypes should remain the same.
00489  *
00490  * This partially replaces one function. The header file from mbed TLS is still
00491  * used, in contrast to the MBEDTLS_ECP_ALT flag. The original implementation
00492  * is still present and it is used for group structures not supported by the
00493  * alternative.
00494  *
00495  * Any of these options become available by defining MBEDTLS_ECP_INTERNAL_ALT
00496  * and implementing the following functions:
00497  *      unsigned char mbedtls_internal_ecp_grp_capable(
00498  *          const mbedtls_ecp_group *grp )
00499  *      int  mbedtls_internal_ecp_init( const mbedtls_ecp_group *grp )
00500  *      void mbedtls_internal_ecp_free( const mbedtls_ecp_group *grp )
00501  * The mbedtls_internal_ecp_grp_capable function should return 1 if the
00502  * replacement functions implement arithmetic for the given group and 0
00503  * otherwise.
00504  * The functions mbedtls_internal_ecp_init and mbedtls_internal_ecp_free are
00505  * called before and after each point operation and provide an opportunity to
00506  * implement optimized set up and tear down instructions.
00507  *
00508  * Example: In case you uncomment MBEDTLS_ECP_INTERNAL_ALT and
00509  * MBEDTLS_ECP_DOUBLE_JAC_ALT, mbed TLS will still provide the ecp_double_jac
00510  * function, but will use your mbedtls_internal_ecp_double_jac if the group is
00511  * supported (your mbedtls_internal_ecp_grp_capable function returns 1 when
00512  * receives it as an argument). If the group is not supported then the original
00513  * implementation is used. The other functions and the definition of
00514  * mbedtls_ecp_group and mbedtls_ecp_point will not change, so your
00515  * implementation of mbedtls_internal_ecp_double_jac and
00516  * mbedtls_internal_ecp_grp_capable must be compatible with this definition.
00517  *

03339  * \brief       This macro is invoked by the library when an invalid parameter
03340  *              is detected that is only checked with #MBEDTLS_CHECK_PARAMS
03341  *              (see the documentation of that option for context).
03342  *
03343  *              When you leave this undefined here, the library provides
03344  *              a default definition. If the macro #MBEDTLS_CHECK_PARAMS_ASSERT
03345  *              is defined, the default definition is `assert(cond)`,
03346  *              otherwise the default definition calls a function
03347  *              mbedtls_param_failed(). This function is declared in
03348  *              `platform_util.h` for the benefit of the library, but
03349  *              you need to define in your application.
03350  *
03351  *              When you define this here, this replaces the default
03352  *              definition in platform_util.h (which no longer declares the
03353  *              function mbedtls_param_failed()) and it is your responsibility
03354  *              to make sure this macro expands to something suitable (in
03355  *              particular, that all the necessary declarations are visible
03356  *              from within the library - you can ensure that by providing
03357  *              them in this file next to the macro definition).
03358  *              If you define this macro to call `assert`, also define
03359  *              #MBEDTLS_CHECK_PARAMS_ASSERT so that library source files
03360  *              include `<assert.h>`.
03361  *
03362  *              Note that you may define this macro to expand to nothing, in
03363  *              which case you don't have to worry about declarations or
03364  *              definitions. However, you will then be notified about invalid
03365  *              parameters only in non-void functions, and void function will
03366  *              just silently return early on invalid parameters, which
03367  *              partially negates the benefits of enabling
03368  *              #MBEDTLS_CHECK_PARAMS in the first place, so is discouraged.
