/**
* \file ctr_drbg.h
*
* \brief This file contains definitions and functions for the
* CTR_DRBG pseudorandom generator.
* \brief CTR_DRBG is based on AES-256, as defined in <em>NIST SP 800-90A:
* Recommendation for Random Number Generation Using Deterministic
* Random Bit Generators</em>.
*
* CTR_DRBG is a standardized way of building a PRNG from a block-cipher
* in counter mode operation, as defined in <em>NIST SP 800-90A:
* Recommendation for Random Number Generation Using Deterministic Random
* Bit Generators</em>.
*
* The Mbed TLS implementation of CTR_DRBG uses AES-256 (default) or AES-128
* (if \c MBEDTLS_CTR_DRBG_USE_128_BIT_KEY is enabled at compile time)
* as the underlying block cipher, with a derivation function.
* The initial seeding grabs #MBEDTLS_CTR_DRBG_ENTROPY_LEN bytes of entropy.
* See the documentation of mbedtls_ctr_drbg_seed() for more details.
*
* Based on NIST SP 800-90A §10.2.1 table 3 and NIST SP 800-57 part 1 table 2,
* here are the security strengths achieved in typical configuration:
* - 256 bits under the default configuration of the library, with AES-256
* and with #MBEDTLS_CTR_DRBG_ENTROPY_LEN set to 48 or more.
* - 256 bits if AES-256 is used, #MBEDTLS_CTR_DRBG_ENTROPY_LEN is set
* to 32 or more, and the DRBG is initialized with an explicit
* nonce in the \c custom parameter to mbedtls_ctr_drbg_seed().
* - 128 bits if AES-256 is used but #MBEDTLS_CTR_DRBG_ENTROPY_LEN is
* between 24 and 47 and the DRBG is not initialized with an explicit
* nonce (see mbedtls_ctr_drbg_seed()).
* - 128 bits if AES-128 is used (\c MBEDTLS_CTR_DRBG_USE_128_BIT_KEY enabled)
* and #MBEDTLS_CTR_DRBG_ENTROPY_LEN is set to 24 or more (which is
* always the case unless it is explicitly set to a different value
* in config.h).
*
* Note that the value of #MBEDTLS_CTR_DRBG_ENTROPY_LEN defaults to:
* - \c 48 if the module \c MBEDTLS_SHA512_C is enabled and the symbol
* \c MBEDTLS_ENTROPY_FORCE_SHA256 is disabled at compile time.
* This is the default configuration of the library.
* - \c 32 if the module \c MBEDTLS_SHA512_C is disabled at compile time.
* - \c 32 if \c MBEDTLS_ENTROPY_FORCE_SHA256 is enabled at compile time.
