* track of the ratio of application data and TLS overhead would be too much.
*
* Mandatory security-related configuration:
* - define ALTCP_MBEDTLS_RNG_FN to a custom GOOD rng function returning 0 on success:
* int my_rng_fn(void *ctx, unsigned char *buffer , size_t len)
* - define ALTCP_MBEDTLS_RNG_FN to mbedtls_entropy_func to use the standard mbedTLS
* entropy and ensure to add at least one strong entropy source to your mbedtls port
* (implement mbedtls_platform_entropy_poll or mbedtls_hardware_poll providing strong
* entropy)
* - define ALTCP_MBEDTLS_ENTROPY_PTR and ALTCP_MBEDTLS_ENTROPY_LEN to something providing
* GOOD custom entropy
