That's because it is impossible to break the code when we do not know what is supposed to be there.
If I create some kind of code (like I did when I was young, so that I could write things without my brother understanding what it was
) you will
have a hard time breaking it because it will be to write in my own language (unless you know Portuguese and you try to see if you can make any sense
of it in Portuguese) and are not expecting it.
Also, a code that is made in a way in which the symbols change with the position on the word or sentence makes it almost impossible to break. If the
code changes in each message it makes it even more difficult. A code in which each character represents a word in a specific position in a list that
only the person that made the message or to which the message is intended is impossible to break if you don't have the list (that was what happened
in World War II, the US could only understand the Japanese messages after a fisherman found the code book from a Japanese admiral that was killed in
an aeroplane crash in the ocean, I think near the Philippines).
So an unbreakable code is not that difficult to create, it just takes a little work.
PS: if it does make sense then it's also impossible to break.
PPS: the German code used during World War II was discovered because they made a mistake and repeated one of the sequences instead of changing it from
the one used on the previous message.
PPPS: my brother never succeeded in breaking my code.
