If you say that AES256 needs CSPRNG seeding with 256 bits, then why doesn't RSA
2048 keygen need seed to be seeded with 2048 bits? I am not a cryptographer,
but I do not agree with this argument
algorithms with a security level of 256 bit in TLS (like AES-256-CTR),
so it is necessary that the random generator provides this level of
security.
But if it is true, an AES128-CTR DRBG is still sufficient for generating keys.
For the same reason that it is sufficient for generating Ed4418 or RSA2048 keys.

We are not going for FIPS validation here. This might be a nice to have, but
it is *NOT* a requirement for this release. Especially if it puts the seeding
requirement beyond the reach of some of our supported platforms.
