So in the example above, XYZ are added at the front of the new alphabet. Step 4 – At the end of the alphabet, take the missing letters and add them at the front. So write another alphabet underneath the original one, starting under the third letter. In the example above where the key is 3, the alphabet is moved 3 spaces. Step 3 : Count the amount of spaces to the right using the number that you chose in the previous step. this number will represent the “Key ” value that will be used to “shift” the alphabet. Steps 2 : You choose a number between 1 to 26. So this will represent your standard Alphabet. Problem is, its easy to crack!Ĭheck out the steps to create a Caesar Cipher Decoder message below:Ĭaesar Cipher decoder – Write down the Alphabet – A-Z on a sheet of paper. so you can make an encrypted message from this simple cypher. Now if the Key is 1, then A = b, C = d etc. For example, a Key of 0 means that the two red A’s are lined up together so that Z = z, and T = t etc. This means that the inner ring for the cipher text has been moved 19 places. So you have the larger plaintext ring with the 26 letters of the alphabet, and you have the inner ring which is for cipher text. In this illustration we can see the Caesar Cipher Decoder. The Caesar Cipher Decoder Caesar Cipher Decoder You can watch this video below, or further down I walk you through the video steps. So Lets have a look at the Caesar Cipher. I addition, we will look at the reasons why the Caesar Cipher is so easily cracked! In doing so, you will be able to apply the cipher to encrypt a plaintext message, and decrypt a ciphertext message. In this post we will be helping you to get familiar with the Caesar Cipher, a simple method of encryption.
