Where do you get binary decoder/encoder? my calculator only can do for under 1024... guess to do this puzzle with pencil and paper again... my theories is add the number to form a letter and do this by four group of numbers... am I right?   |

You can write a computer program to convert even very large numbers to binary. There is no "grouping" in this one. Characters are represented as 8-bit numbers, then encoded.

Woah, there are way more serious cryptic messages here than I first thought! I am actually an amateur when it comes to this trade, so when encryption goes beyond singular levels of logic, I really need much time to ponder through it. Unfortunately, I don't have the time for that at the moment (busy at school).. I only stay here until I finished all my Anime music downloads. Then the rest for my sleep. ^O^ But I really would love to study this one, but I just don't have the time (and tranquility) my mind needs. (I did studied it for a short time and now I dragged it along to school until I couldn't concentrate on my lectures!) Ok, now enough for my excuses.. lol PS: I just saw these Cryptic Games on the mainpage yesterday, and I somehow managed to answer the other one. And now, I think I should stay away for more of this at the moment. Haha. Later! |

Come on, guys, I can't still be the only one who's solved this. Hints: 1: The information is all there; you don't have to apply any full-on decryption, you just have to read it off the correct way. 2: It's no coincidence that all the numbers are even. If this is too much of a hint, Gendou, feel free to delete this post. It just makes me sad to see only my name on the score chart. |

i have a question. is it a gemometric sequence or arathmatic or somthing totaly diffrent. it looks to be geometric though. all people will take time for death, only a few will take time to live.

interesting question. it is not a mathematical sequence, it is an encoded message. the encoding method involves a specific application of binary ascii data to a list of numbers. it involves expansion, doubling to be specific. understanding this much, one should be able to infer what is going on from the patterns in the binary as presented by natzor.

okay i see so you take the nubers from one sequnce and then add them to the second and so on right. that explians the repition atleast. i don't know im way of base all people will take time for death, only a few will take time to live.

Gendou... I am able to see the pattern between "a", "b", and "ab" (took me a while)... but.... could I ask you to check the hints for "c" and "abc" ? It appears that there's one bit in the decrypted data that is causing me some confusion.... |

Re: Cryptography Challenge #17!

it's pattern recognition... so far, the publicly given hints have been this: convert the sequence of numbers to a sequence of binary... use the hint examples ("a", "b", "ab", etc.) to figure out how additional bytes in the secret message is added to the cryptic message, and with that knowledge, recognize patterns of bits, chopping the msg down from 1024 integers ranging from 0 to 2047 (which equates to a total of 11264 bits), down to the appropriate 180 (177) bytes (which is 1440 bits) (all of what i just said has been previously stated in one form or another in previous posts, so I gave no new information yet) oh, and don't try to use the codes given for "A", "B", or "AB" from the hint for anything other than trying to recognize the pattern |

this is verry interesting ... will try and c if i can crack it :) not to much math i have to do more along the lines of some binery codeing shouldint be to hard ... i hope :D

I think I've been solving this challenge for at least two years now! (Joke! I stopped solving these challenges during my 4th year college.) This was one of the first challenges that I have seen and tried to solve when I first saw your cryptography challenges, and I believe that this is a difficult one. I was wondering why "a" would be represented by 1 1 1 1 5 5 5 5, is it related to its ASCII value or something? Or is it just the initial value then the sequence should be followed to get "b", "c", etc.?  |

Icepolar, try looking at the binary representation of A, B, and C (hints 1, 2, and 3, respectively) next to each other. There is a pattern, keep pondering the examples until you see it!

I'll try to focus on that, but I think I'm a little confused (actually I'm "quite" confused... :|) when trying to compare A, B, and "AB" side by side. I see the A's bits but is lost with how B is in it. If my assumption is correct, the pattern is the key. I won't give up... Ü |

Ahhhaaaahaha!! I am the 10th person to get this right omg xDD I wish I know some computer science or programming skills so I don't need to translate every bit and bytes manually QwQ (Also I wouldn have decoded faster if I've known some computer coding, *semi-spoiler* hehe) I think Gendou already gave quite a few huge hints for this problem "(2^n)-1 sequence" (i.e. 2-1, 4-1, 8-1, 16-1... etc) "try turning the binary output 90" These hints are huge acknowledgement of my hypothesis of the encrypting method Given that, I now understand why you're surprise so few people figure this one out. >w> Once again, really appreciate for your puzzle :p |
