/**
* \def MBEDTLS_CHECK_PARAMS
*
* This configuration controls whether the library validates parameters passed
* to it.
*
* Application code that deals with 3rd party input may wish to enable such
* validation, whilst code on closed systems, such as embedded systems, where
* the input is controlled and predictable, may wish to disable it entirely to
* reduce the code size of the library.
*
* When the symbol is not defined, no parameter validation except that required
* to ensure the integrity or security of the library are performed.
*
* When the symbol is defined, all parameters will be validated, and an error
* code returned where appropriate.
