\def MBEDTLS_CMAC_C Enable the CMAC (Cipher-based Message Authentication Code) mode for block ciphers. Module: library/cmac.c Requires: MBEDTLS_AES_C or MBEDTLS_DES_C \def MBEDTLS_CTR_DRBG_C Enable the CTR_DRBG AES-based random generator. The CTR_DRBG generator uses AES-256 by default. To use AES-128 instead, enable MBEDTLS_CTR_DRBG_USE_128_BIT_KEY below. Module: library/ctr_drbg.c Caller: Requires: MBEDTLS_AES_C This module provides the CTR_DRBG AES random number generator.
