/**
* \def MBEDTLS_CHECK_PARAMS
*
* This configuration option controls whether the library validates more of
* the parameters passed to it.
*
* When this flag is not defined, the library only attempts to validate an
* input parameter if: (1) they may come from the outside world (such as the
* network, the filesystem, etc.) or (2) not validating them could result in
* internal memory errors such as overflowing a buffer controlled by the
* library. On the other hand, it doesn't attempt to validate parameters whose
* values are fully controlled by the application (such as pointers).
*
* When this flag is defined, the library additionally attempts to validate
* parameters that are fully controlled by the application, and should always
* be valid if the application code is fully correct and trusted.
*
* For example, when a function accepts as input a pointer to a buffer that may
* contain untrusted data, and its documentation mentions that this pointer
* must not be NULL:
* - the pointer is checked to be non-NULL only if this option is enabled
* - the content of the buffer is always validated
*
* When this flag is defined, if a library function receives a parameter that
* is invalid, it will:
* - invoke the macro MBEDTLS_PARAM_FAILED() which by default expands to a
* call to the function mbedtls_param_failed()
* - immediately return (with a specific error code unless the function
* returns void and can't communicate an error).
*
* When defining this flag, you also need to:
* - either provide a definition of the function mbedtls_param_failed() in
* your application (see platform_util.h for its prototype) as the library
* calls that function, but does not provide a default definition for it,
* - or provide a different definition of the macro MBEDTLS_PARAM_FAILED()
* below if the above mechanism is not flexible enough to suit your needs.
* See the documentation of this macro later in this file.
*
* Uncomment to enable validation of application-controlled parameters.

*
* This only applies to functions whose documentation

* - about 3300 basic operations for P-256
* - about 9400 basic operations for P-384
*

* lower value. That minimum depends on the curve size, and
* can be made lower by decreasing the value of
