For example, the following construction:
Start with an RNG. Retrieve 64K of random data. Assume there might be a
bias somewhere in there, but that at least 256 bits are good. SHA-256 the
data. AES-256 encrypt the data with the result from the SHA-256.

Remember the Clipper chip?
Clipper (or more specifically Capstone, via the Fortezza card) is a great
example of the NSA's sound engineering approach to generating random data [0].
They used a physical randomness source of an unpublished type,
