Any distribution with a sufficient amount of entropy can be turned into "cryptographic-grade" randomness source using randomness extractors [1]. These work independently of any outside factors that might be trying to sneak signal (e.g. periodicity) into the noise -- as long as you can prove there's sufficient entropy to start with, you're good to go.

  Once you get 16-48ish bytes depending on paranoia you can just rely on crypto
