 Hence NIST SP 800-90B cite:[TuBaKe:18] min-entropy assessment must
 guarantee at least 128 + 64 = 192 bits input entropy per 256-bit block

 Only then a hashing of 16 * 16 = 256 bits from the entropy source
 will produce the desired 128 bits of full entropy. This follows from
 the specific requirements, threat model, and distinguishability proof
