Hmm . . . . So follow the spec, and if you don't have a spec . . ..

So you are saying position may matter. Which is better then, Prefix or Suffix?

comment Feedback on rolling my own entropy gatherer
So you are saying collect the whole message (including parts that are always the same), don't bother stirring it, and then use a SHA-256 hash to retrieve a value to use as a seed? How often should the pool be flushed or new entropy be gathered?

@mikeazo: So as long as Random.org is not the attacker it would work.

So there is no use for them in cryptography?
