Wait not that Caesar. This Caesar
Yep Caesar cipher. You might have heard of it by other names like ROT or shift cipher.
So the reason for the break between the 4 first lessons and this next segment was because I wanted to see how people responded to them and what you guys enjoyed and disliked in them. And one of the things I got alot after solving the live passcodes was something like this “Ok very nice hexadecimal, decimal, etc, etc but now you are talking about stuff that does not involve any ranges. How did you get there ?”
Well normally my reaction when facing a puzzle I cannot convert to any of those nice ranges we mentioned in the previous lessons, is to start trying other kinds of ciphers. The most easy of all them and the one I tend to try out first is the caesar shift.
So what does it do? It basically replaces letters with other letters. In order to do that it moves a certain numbers of positions in the alphabet .
For example the letter A with a Caesar of 1 (or ROT -1 or ROT 25) becomes a B.
If the value was 2 it would be a C. So as you can see this makes the values of the shifts between 1 and 25 (you can do more but you would just be doing full spins inside the alphabet )
One of the most famous of the shifts is the ROT 13 . Why? Because ROT 13 ends being his own reverse in the latin alphabet .
Let’s see an example. Here is the original
same / fnzr
Now we ROT 13 it
As you can see ROT 13 can be both an encoder and a decoder.
So that’s pretty much the basics of a Caesar cipher. Shall we move to more pratical trials then.
So as usual the correct answer to these will be a link that takes you to an image of an ingress item. These are meant as little victories and do not provide any bonus in ingress. At least for now. But using the knowledge here can help you decode passcodes of the game later.
But today there is a a new thing. The puzzles will be layered. This means to reach puzzle 2 you will have to solve level 1 first. And of course the difficulty will increase. There are 4 puzzles to solve
