- * as the underlying block cipher.
+ * (if \c MBEDTLS_CTR_DRBG_USE_128_BIT_KEY is enabled at compile time)
+ * as the underlying block cipher, with a derivation function.

+ * 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

+ * 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.
