Sometimes I like to mislead people. Like solving something in a wrong way, or making them search for things in the wrong place. However, I keep things in the field. If I'm going outside the field, I make sure they know.

I hope you come back to solve this. Already 2 people made it to the end.

I didn't save the code used to crack the cipher. Damn :/

There are other ways to do it. Easily. Regardless of the fact taht I hid a lot of things in it.

Random fact: Whenever I'm stuck in something, I try to understand its source.
Random fact1: Arabs used to cipher their letters by making each character of their sentences bold.
Random fact2: I'm half Arab.
Random fact3: These facts aren't facts.
Random fact4: Someone who uses 0-indexing is probably a liar.
Random fact5: 'Palindrome' is not a palindrome. (Thanks @gorok).
Random fact6: If you multiply a number by its inverse with a modulaire you get 1.

8 years ago

Is it clear when I find this right place?

8 years ago

You'll know the answer when you see it. It's right in front of your eyes but also hidden.

8 years ago

So, what do I have to do if i think I've decoded it???

8 years ago

Comment has been collapsed.

If you really decoded it. You wouldn't need to ask me!!

8 years ago

Comment has been collapsed.

Well, I suppose I've read the decrypted text, seen and understood your first fact and now i'm confuzzled....

8 years ago

Comment has been collapsed.

Have you read all my random facts? The obvious and the hidden?

8 years ago

Comment has been collapsed.

I've been at this for too long . . . and from what I can make of this:
1) The cipher appears to be fairly obvious (although it's not clear to me whether I should be using the PlainText or encypted version).
2) I think the key can be easily found if you look in the right place (as you suggested).

But, I can't seem to do the basic decryption to the right solution, so I must have something wrong.

8 years ago

Comment has been collapsed.

Well, it's been a day ago and only 3 solvers. I guess I gotta step in and help you guys.

HINT OF ALL HINTS: I am the master of misleading people, there are several(not really, just a few) pathways to do this. Some are veery necesary and can help you undersatnd what you're going and some can be ignored if you already have the knowledge. Simply put, if you think you're doing it right but you can't seem to reach the end, find a different way to do it.

8 years ago

Comment has been collapsed.

Another thing to add. I hide things among things.

Decryption is not the hard part. I don't know what to do with it.

Make sure you read everything I said in this discussion. I've hinted to the correct steps several times. You might also want to open your eyes for hidden things, in plain sight

I saw them but they didn't lead me anywhere.

My reply to someone else

If I was the one who made the puzzle, I'd make the first step as a first random fact. Oh wait, I did!

8 years ago

Comment has been collapsed.

Yep, been there, learnt about a Frenchman I'd never heard of before, found an example key which may or may not have been a red herring, but couldn't be used successfully in either a tabulated or algebraic method - hence getting confused as to what is real and what is deception.

8 years ago

Comment has been collapsed.

This puzzle indeed has a lot of rabbit holes and deceptions. But I made sure that when you see the answer, you know it's the one you seek. How hard is it to see this ?

8 years ago

Comment has been collapsed.

In the original message - easy; elsewhere, hard.

8 years ago

Comment has been collapsed.

Misleading you means making you think this is hard, whilst it's easy ;)

8 years ago

Comment has been collapsed.

Don't you feel amazed how people can make a discussion as a reply?

8 years ago

Comment has been collapsed.

Yep, doesn't help. I've never played with modulo or keys before, and while they're fairly easy to pick up, it's hard to follow when there are rabbit holes along the way, so I have no clue as to whether I'm on the right path or not until I hit the correct solution. Unfortunately for me there are too many possibilities to follow while being blind in doing so (I think I'd be more successful if the path was more clearly linear).

I'll chalk this one up to experience and look forward to seeing the solution.

8 years ago

Comment has been collapsed.

What if the encrypted message IS a rabbit hole? I made a lot of pathways as a part of the puzzle, but their end would always lead you back to the beginning with more gear.

8 years ago

Comment has been collapsed.

Well, I was already halfway through, but I dropped it when I heard the decrypted message leads to nowhere. For sure I'm coming back to this after work tomorrow. Bump.

8 years ago

Comment has been collapsed.

It does lead to something. It's simply a piece of information you might need.

8 years ago

Comment has been collapsed.

To save you guys from doing bullshit math. The modular multiplicative inverse of 7 is 15. Then X=A^(-1)(Y-B) comes in handy.

8 years ago

Comment has been collapsed.

So much time spent on deciphering the whole message... I deciphered it. But for nothing? :( That's plain evil...
Also the "simple hidden thing" did not help at all, even ciphered and deciphered it, and it was still a useless clue.... You can't expect us to be in your mind on what to do after the deciphering. This is crazy man...

8 years ago*

Comment has been collapsed.

Deciphering the message is somewhat necessary for people who don't know what they're doing. It can be ignored if you already found the true hidden message.(You already did btw). You probably missed several other hints.

You know hiding can also be done in comments ;)

8 years ago

Comment has been collapsed.

I've read your comments indeed but they helped me not. I seriously don't know what "I'm supposed" to do next, so I'll just wait for the posted solution in the end... This has already took too much of my time, sorry, and it just makes no sense to me what you expect us to do/understand...

8 years ago*

Comment has been collapsed.

"The simple hidden thing" IS the fist step. I hid a hint in a veeery obvious place since I made it soo big and shiny, that tells you what to do with it. Don't lose hope, please!

Bump for massive amount of red herrings.

Shouldn't letter 'D' be '3', with 0-indexing? It's 5 in your hint on the original post.

8 years ago

Comment has been collapsed.

Haha yeah you're right, honest mistake.

8 years ago

Comment has been collapsed.

I think he is just referring to it, in order to demonstrate that it's necessary to also count "0" in the function.. It's just an example.

8 years ago

Comment has been collapsed.

Yeah, it was an example indeed. But good catch from his side.

8 years ago

Comment has been collapsed.

I had actually seen that from the beginning, but never cared to mention it, since it was an example of a function that "would not work" as far as the necessity of 0 goes. :P but oh well...

8 years ago

Comment has been collapsed.

Yep, although I re-read every word there has been put as a hint and I always try to find a meaning behind them.

8 years ago

Comment has been collapsed.

Good job realising that. I indeed hinted all of the steps(except for the last one) in every comment I made, I even hid stuff in my comments. Here, I said it!!

8 years ago

Comment has been collapsed.

I'm probably blind then, or fail to understand basic things, cause I can't see a single thing that helps in your comments. Anyway I give up...

8 years ago

There is a big giant massive vast comment that says this is a hint.

Yes of course I'm checking what I can on hints. But you guys are obviously a different level than me in puzzle-solving... In any case this is my last post here, I think I've spammed enough... You are all crazy to be able to solve this...

8 years ago

The only thing requires is patience and consistency. It took me 2 hours to solve a jigsaw puzzle yesterday because I knew I can do it. You also do know you can do it, you already have the right pieces, just make sure you understand them.

Reading the very end of the puzzle doesn't require maths.

Not a problem . . . except now you've taken me to your new puzzle which looks very interesting!
You know these puzzles feel a lot like work. I get through one and feel like I deserve a break, and then bang, I'm slapped with another one to tackle. My addictive personality being like a dog with a bone doesn't help as I can't just walk away.

Two people solved it without the hints.

8 years ago

Comment has been collapsed.

Oh I recognize that, and good on them. However from my perspective, this is a puzzle that has a very large number of red herrings, things that look cool, but ultimately go nowhere. This leaves you fundamentally with three options:
1) Get lucky. Happen upon one of the correct paths soon, and hooray, you get there
2) Spend a lot of time. Chase down each of the red herrings, and work out whether it is real
3) Use the hints to eliminate a number of the red herrings, reducing the time commitment to what you have available.

Now I admit it. I am time poor. I have a lot of commitments, and not a huge amount of time, which ruled out option 2 for me, and by chance I was unfortunately not lucky. That left option 3 as MY only route through. Someone else could have ended up on either of the other two options.

From my perspective, I really liked the core mechanic. I liked where and how you chose to hide the Itstoohard code. Frankly, you did not need all of the red herrings to get to a cool puzzle. You had one to start with.

8 years ago

Comment has been collapsed.

I'd like to answer you, but I'll leave the answer until the giveaways end. Since I my answer would be the answer to the puzzle.

8 years ago

Comment has been collapsed.

The red herrings were intended. Just wanted to make it slightly harder by confusing people. I provided hints to help you recognize the red herrings, though.

8 years ago

Comment has been collapsed.

Bump for not solved, don't have the slightest idea after staring at screen and thinking for 30+ min

8 years ago

Comment has been collapsed.

You don't need to think a looot. What progress you made so far?

8 years ago

Comment has been collapsed.

I have some leads. But the math part got me so lazyyyyy, and I didn't know how to to decrypt the sentence.

I guess I saw your hint with source if you're talking about the strongs, and I saw that there's a trick somewhere, but I'm lost. Math doesn't make me want to go very far. :c

8 years ago

Comment has been collapsed.

Well, the math part isn't entirely necessary. You can fully skip it if you know what to exactly do with the ciphered message.
