about substitute teacher

[martin_great_boy]

what kind of code used?



plisss help me

[sky]

As the name of the challenge suggest, it uses a simple substitution cipher (http://en.wikipedia.org/wiki/Substitution_cipher)

in substitusion simple it doesn't work,



please give me some hint...

The basics of crypto (and by basics I mean you should have figured that out on you're own) is to know english
What I mean is that there are only a few common 2 or 3 letter words therefore you could start off by replacing small words first by guessing and then bigger words
You should get something eventually

Another key when dealing with harder encryptions (XECryption is my favorite) is remembering what are the most common used letters (and characters) and what they can be associated with (Hex, Bin, HTML...)

Hope it helps

PLEASEE... i don't understand at all about this challenge... so confusing... please give me an information and a clue to solve this challenge... thanks so much..

The problem with substitution is most of the methods of solving it require you to know what the substitutions for the letters are. If there were some brute force way to try all different substitutions until an answer that made sense was found...

XECryption is my favorites

We all learn somewhere

wait which one are you talking about, is it the newsgroup cipher, if not how do you solve that one
?

[Hi!!!]

I solved all of the cyphers so far by knowing all of the codes contain the word "answer." I then find all of the 5 letter words in the code and substitute it in (usually there is only a few). If the five letter coded word has a three letter coded word in front of it, I would guess that the word is "the" and double check it with the coded word that means "answer" to see if the "e"s match up.

Hope this gives you a big push in the right direction!

Hi,
I wanted to ask if I need to differ between capitals or non capitals. What is the first character from "teacher", I am supposed to use?

[wannabe]

I started writing useless programs and started to wonder more and more. A little hint from me is, just use the editor.

I still have no idea about this challenge. I think I have tried words like 'answer', 'the', 'is', 'this' but still I cannot get the answer. Could anybody give me more hints?

[Karian]

try harder.

http://en.wikipedia.org/wiki/Substitute:
-> "Substitute means to replace one thing with another." <-

The most frequent character in the English language is the 'e' !
