How are people able to decode messages with random letters?

I just do not understand it. If I made a code like this erdgmrkdlgmrglkmrdglrmeglk , how would one go about deciphering it? It could literally mean anything. Put that code I just put in a decoder. How would it figure out what I was saying?

Answers:

A question like this is best answered if you look for TV documentaries on Allies breaking Nazi Enigma.

Keywords, Bletchley Park, Enigma, Polish, Turing, Kriegsmarine, Bombe, Colossus.

A language has syntax. How will I go there? Can be Izx mytt F sz glbib? Now I look at this and go F is I or A as there is only two words that can be single. H'r would be I'm as there is no other thing it could be. Mytt. Can be a bunch of things but ??ll is a good guess start as any. If tt = ll then y has to be a vowel. You have to know the language and this is a simple code called a cryptoquote which I do every day in the newspaper. My favorite combination is hvth or something the same. Normally it is THAT, but it can be ELSE or SAYS. I look at the "words" around it to get a feel for which it may be. You have to practice at it and many codes are more complicated. In WWII Navajos were the code talkers. They communicated sensitive information in Navajo and the Germans could never figure it out. Of course they were rewarded, as usual, by being sent back to the reservation. People are nasty.

If it's a cryptogram, a simple substitution cipher, you can look for patterns of letters and which letters are most common. Cryptograms in puzzle magazines usually have the letters arranged in words, making them easier to decode.

If they are truly random letters then there is nothing there to decode.

When a string is encoded it is following rules and you have to know the rules for decoding it. The whole purpose of encoding a string is to prevent someone like you from decoding it.

Before you focus on deciphering something, you should focus on encoding a string. How would you choose to do it?

If you are asking about this subject, what do you already know? Do you understand a simply Caesar cipher? That's where each letter is encoded to be the letter 2, 3 or maybe 4 ahead of it. WIth 2:

A-->C
B-->D
...
Y-->A
Z-->B

As you can see, it wraps around at the end.

If you are not already familiar with encoding and decoding such a message, then you need to start from the beginning. Go to the library and ask the librarian to help you find a book.

By the way, when you have a very short ciphertext there usually isn't much to go on regarding trying to find a pattern. If the text is a puzzle that is MEANT to be solved by a non-expert then brute force is usually used -- going through the most common simple codes.

If your code was ALL random letters, then obviously it couldn't be deciphered. However, if a random letter was inserted after every two (or three, or...) letters, then the code could be deciphered, by filtering out every third (or fourth, or...) letter. Hope I helped.
