Has any illegal data been saved in the Block Chain, such as an illegal number, or illegal prime?

While working on my master thesis I used the AACS encryption key (09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0), considered an illegal number, as a basis for creating a fake Bitcoin address - 1ujTAfEQh2obwdt72GrmXonakx2RxvYpX. A 1 Satoshi transaction was sent to that address from address 17TQLZvXjKTrUyRnV9DuQs4RVDgNjUPeXQ. The transaction was encoded in block 177653.

  • Wouldn't it be easier to just have the hex string 09f911029d74e35bd84156c5635688c0 be the private exponent? That makes the unused address 1KyKqNh9fM5sN8uWDLXNv2o52sqj94GhbN. (Generated using brainwallet.org) – lurf jurv Feb 6 '13 at 3:33
  • @lurfjurv But then you are not storing the illegal number, but some derivation of it which is technically not illegal. – ThePiachu Feb 6 '13 at 5:54
  • Oh. How does 1ujTAfEQh2obwdt72GrmXonakx2RxvYpX represent that number, then? – lurf jurv Feb 8 '13 at 16:07

    @lurfjurv It's hash160 (as in, hex version of the address that is a part of the block now) is 09f911029d74e35bd84156c5635688c000000000 . – ThePiachu Feb 9 '13 at 8:54
