Q&A for How to Write in Code

Yes. Atbash is a mono-alphabetic substitution cipher originally used to encode the Hebrew alphabet.

Yes, you can do whatever you please. Just remember how to decode it, or you're just left with some wacky thing.

You can use Morse code in communicating with someone who knows it or has a key to decipher it. But be careful: people who you do not want to understand the message may also know Morse code.

You can align every letter in the alphabet to another letter in the alphabet to create your own code.

There are an infinite number of codes, as there are an infinite number of possible combinations you can make.

Technically, you could read it however you want if you try hard enough, but using a mirror is the easiest way.

No, it should not be hard to make a code and decode it, as long as you know how to decode the message.

You can put as many letters as you want in a row in a block cipher method, as long as that number is smaller than the number of characters in your message.

Yes, pigpen is an example of a mono-alphabetic substitution cipher.

Simple ones, like writing backward, reversing the alphabet and using the numbers instead of letters.

Well, you can use the hex code and turn it to a colour, for example, a52a2a becomes brown.

Yes, but if you are writing to friends in this code and someone sees it, there is a higher chance of them knowing what you are saying because they might have studied those languages.

Number 3 is in Egyptian hieroglyphs so you cannot use your own drawings but, number 4 allows you to use your own drawings to represent a letter.
