comment How should I diagnose a macintosh laptop running OS X Lion 10.7.5 automatically booting at 12:00:09 sharp every night?
But none of this should happen if the computer is turned off. Why would it boot up like this? What if I don't want it to boot up automatically?

comment Clarification on how rainbow tables work
Hi Thomas - I have updated my question above with new code sample to reflect my understanding of what you said. The code should not be lazy anymore because if it fails matching an endpoint, I compute H(R(w)) and try to find a match in endpoints again. If no match, I compute H(R(H(R(w))) and try again. If however, I do find match in endpoints, I iterate backwards in that chain (or forward from starting point) the number of times I hashed "w" and guess the potential password. But I always get 00000000000000000000000000000084 as a false positive. is there something I missed?

comment Clarification on how rainbow tables work
Hi Thomas - First off, this is an wonderful explanation. I would have given you 100 points for this if stack exchange allowed :). I will try to implement the way you have said it. However, I did notice that from your explanation of endpoint it seems like the endpoint is a 128 bit hash, however the Wikiepedia article stores only the reduced version (i.e. the endpoint should be in the password space). But I think your way makes more sense and I'm implementing what you said now and will report back here with my results.

comment Clarification on how rainbow tables work
Hi Henning - No I did not mix up the plaintext and password. The key is all zeros as I said and the password is "0x56". The rainbow table is constructed using all-zero key. You have to pretend as though you do not know "0x56" is the password. The only thing we know about the password is it is 2-hex characters and was encrypted with a key that is all zeros. We also know the AES of the password is 1bb171d2afef6e7f1ccb895ee9b35fe0.
