How to come up with a new cipher?

Alfabet Morse’a, GA-DE-RY-PO-LU-KI, Caesar Cipher ... we all know them and are happy to use them. Gladly, that is, often. Today, however, we will come up with a cipher, which no one but us can read. Or maybe, together with your host you will come up with a different one, which only you will use?

There are plenty of possibilities, and you are only limited by your imagination!

The "Ravens" team. What sound do these birds make? Kraa! Let's take this as a starting point.

There are plenty of possibilities, and you are only limited by your imagination!

Substitute “Ravens”. What sound do these birds make? Kraa! Let's take this as a starting point.

KRAA!

Hmmm… What can be done about it? Let's put a letter anywhere in the word!

Kraah!Kraaa!Krraa!Krcaa!Kreaa!Krraa!Krzaa!

Do you know what I encrypted above? if not, remove the keyword from the entire message “Kraa!”

Kraah!Kraaa!Krraa!Krcaa!Kreaa!Krraa!KrWithaa!

So this cipher will have the following rules.

  • The key word is KRAA!

  • To encrypt the message with it, put any letter in the key word.

  • If the letter is already in the keyword- repeat it.

  • Ustalmy, that the end of the letter is one exclamation point, end of a word- two, a sentences- three exclamation marks.

  • To further confuse people who will want to read the cipher, try to put the letters like this, to create an already existing word, e.g.. Crab! Krata! Koraa! Kuraa! (the hidden letters are B in turn, T, O, U)

“Collection tomorrow, Fr. 17:00” so it might look like this:

Krzaa!Crab!Kiraa!Chora!Krraa!Kkraa!Kraaa!!Kraaj!Kuraa!

Krata!Krraa!Koraa!!Koraa!!17:00!!!

KrWithaa!Kraab!Kiraa!Kohraa!Krraa!Kkraa!Kraaa!!Kraaj!Kuraa!

Krata!Krraa!KOraa!!KOraa!!17:00!!!

Easy, truth?

Let's think of something else! Maybe let's take the easy way. Enter the word editor WORD (or the like) and rename the font from the default (e.g.. Times New Roman) on “Symbol”.

A

Now just write your message and change the font to “Symbol” i…

Collection tomorrow, Fr. 17:00

It turns to

Collection tomorrow, Fr. 17:00

As you can see, there are many possibilities and enough, that you move your head, and your host will be able to keep their secrets out of sight of other people. Just don't reveal your code key to any unwanted party!
