Assuming the encryption method can create the bit sequence that is the random data. It very well might not. There may be gaps in the encrypted data's number space.

For any non-trivial encryption method, you'd be brute forcing your way through a bunch of them to find the key that can decrypt the random noise to that message. Typical "20 times longer than the existence of the universe" warnings apply. :)



But the encryption method doesn't need to be non-trivial, especially when you define key as anything that

  (a)allows access to the electronic data, or
  (b)facilitates the putting of the data into an intelligible form;


So, if you have a meg of random data, you're thinking you could give them a one meg XOR key that decodes it to an MP3 file of "God Save the Queen"?

Okay. :)
