17:31:24 < eciwllslpknwnspt> hakatak: You know Kerckhoff, right? That's the problem.
17:33:16 < eciwllslpknwnspt> hakatak: I don't see how this is even supposed to be a crypto challenge… Where's the crypto part? So far, I have only seen trivial sudoku solving and my favourite game "guess what awesome system I came up with"
17:35:50 <@hakatak> if anyone is stuck on nikoli, pm me
17:35:55 < eciwllslpknwnspt> hakatak: There's literally an *infinite* number of plaintexts I can "decrypt" out of the sudoku and your "ciphertext" such that it makes sense. How should one guess the right one?
17:37:18 <@LightningTH> well, someone figured out enough of a hint to get it
17:38:15 < eciwllslpknwnspt> LightningTH: no, someone was lucky enough to have a somewhat similar, equally broken idea of "crypto" to figure out what hakatak *may* have thought about when creating that bullshit
17:38:19 < eciwllslpknwnspt> and yes, I *am* mad
