/**
* \def MBEDTLS_AES_ONLY_128_BIT_KEY_LENGTH
*
* Use only 128-bit keys in AES operations.
*
* Uncommenting this macro removes support for AES operations that are using 192
* or 256-bit keys.
*
* Tradeoff: Uncommenting this macro reduces ROM footprint by ~200 bytes.
*
* If uncommented, uncomment also MBEDTLS_CTR_DRBG_USE_128_BIT_KEY
*
* Module: library/aes.c
