That all said, here is the challenge:

- Code: Select all
`fibonacci% 4D667171457A714581A69FEF39E2D51C9C649ECF278150617372A5DC`

The hex in 28 ASCII characters (meaningless at the moment) :

MfqqEzqE.¦Ÿï9âÕ.œdžÏ'.Pasr¥Ü

Any thoughts?

I've got a cipher challenge for something at my school; the rules are that we're only allowed from sources outside of the school, so I'm here. The goal is to learn from the challenge, not just to solve it.

I'm assuming you know what the fibonacci sequence is... In this case, if you interpret the hex as decimal numbers correctly, you can see that it forms a kind of generalization of the fibonacci sequence.

Thanks for the reply! I know what the fibonacci sequence is, though there may be variations of it that I'm unaware of.

I've been working through this for awhile over the past two days and have looked at the decimals several times; I guess I'm just not seeing the pattern you're describing.

The decimals:

Well... this is embarassing. So I wrote a program to convert the hex numbers to decimal, but ended up making a small bug that generated a kind of generalization of the fibonacci sequence, instead of converting the numbers correctly Hence, disregard everything I said in my previous post. I'll take a look at the sequence again when I have some time and see if I can figure it out.

Give you something to start with?

Wow, I had tried that, even have code that does the remainder for values > 256. But I started the fibonacci sequence where the first two values were 0 and 1 rather than 1 and 1. Changed it and it works beautifully. Thanks for the help!
