-
- Well, if the cryptothingies like to think that way, and like to
- limit their thinking in that way, who am I to stop them?? Be my
- guest. I've never presumed to be able to teach anyone how to think.
- I just wondered whether they could overcome a childishly simple
- ONE WORD encryption problem. Just one word. I mean, just one
- word, guy!
-
- > The proposed algorithm seems to do away with keys.
- > Are we assuming right?
-
- I have not described the algorithm or its properties. I have
- described the appearance of its output and would be delighted to
- make a public post of the materials described, or of any other
- materials that would be more to the liking of the cryptomancers
- here. Name your poison and how you want it served, we'll mix it
- and serve it for you. Guaranteed no underhandedness whatsoever -
- just a li'l tough encryption.
-
- But as a concession to establish credibility, I will now say this:
- the NuCrypt algorithm relies on the use of embedded 2048-bit
- shifting keys.
-
- > a) it is a lot easier to imagine than to do.
-
- My point precisely. Easier to theorize than to decrypt.
-
- > b) it is a lot easier to encrypt than to decrypt.
-
- I wonder whether that's necessarily true. Good encryption is not
- "easy", as far as I can tell. In fact, I think it's damn difficult.

-
- Yes, there is such a tendency. Many participants are rather
- conservative. And I do have something, but it wasn't something
- to say, it was something to ask, really. And a little prize
- to offer. Surely that is not so bad, eh?
-
- > The problem is not that the "experts" can't do it; it is

-
- Judging by some of the responses, they do care, but they want it
- given to them on a silver platter ("disclose your algorithm").
- That cannot happen, for many practical reasons.
-
- > You have not managed to give them enough of a challenge...
-
- Well, that's strange. Some here have just said it was *too much*
- of a challenge. But disclosing the algorithm would lessen the
- challenge even more.
-
- > or enough of a reward.
-
- Well, OK, then we'll make the reward a little bigger.
-
- > You are so right about this. But does it always mean
- > that rejected ideas are automatically valid?
-
- No, but neither does it mean that they are not. Really, I'd like
- to point out that am not looking for anyone to determine whether
- my "ideas" are "valid" or "not valid"... that is not the objective.
- The objective was to see whether anyone here could solve a little
- puzzle I was offering. That's all.
-
- > Then it must mean the problem was not laid out in a clear

-
- There was no "problem" to lay out - only a challenge, which was
- rejected by some even before they saw the materials! That in itself
- was interesting. They haven't even seen the "problem".
-
- And there was no misrepresentation that I'm aware of. Why should
- there be? I'd gain nothing from it.
