How Long Does It Take To Play? There is no set length of time that this game will take, and it will vary from child to child. Hint: If your child (or you!) get stuck with working out this code, get them to search for the term ‘Caesar Cipher’ on your favourite search engine, or visit the Wikipedia page about Caesar Ciphers. If you wish, once your child has decoded the question and worked out the answer, they can recode it, and post it as a comment on this post, and I will tell them if it is right or not.

So, here is the coded question, and all the information needed to decode it so you can answer it (you can download a PDF print out of this question from here): If you child enjoys this game, then there are links provided at the end of this post which will help you find other similar activities. That’s OK, but the critical thing is that you let them work it out for themselves by whatever means they can (and this can include looking things up on the internet to help them solve it!). Some kids will get the answer quickly, some will need a little help. The best way to play this game is to give your child this information, and then challenge them to answer the question. In this post, I provide a coded question that you can give to a child, along with enough information to allow them to decode it so that they can answer it (but only just enough information). However, codes are also a great introduction to many other things, including history, mathematics and the computer encryption that much of the modern world runs on. Once you learn how to build an encoder and decoder in a cipher as simple as this one, you'll be able to progress to more difficult ciphers and encryption schemes.The ability to communicate in a way that no one else can understand is something that kids always find fascinating, and this is why playing around with codes is a great way to entertain a child. This is just one of the many ways you can build a Caesar cipher in Python. This method takes the first argument as the plain alphabet and the second argument as the cipher. To do this, I used the str.maketrans() method. This is where the script might start looking a little more intimidating and complex. Next, I created a variable to tell Python how to transpose the message. I added this in to allow for flexibility if I wanted to shift the message by anything other than 13 characters. This means we can execute the function without even giving it the offset and it will, by default, use ROT13. By default, it will shift by 13 characters. This variable tells the function how many characters the message must be shifted. This is the plaintext message that you want to encode. The function requires two variables to work. The first line of code defines the function. Next, I wanted to create a function that would allow me to encode a message. I created a list in a variable called chars and added an uppercase alphabet and a lowercase alphabet. The first thing I did was create a variable that housed all of the possible alphabetic characters (upper and lower case). I created my script in Python 3.8 using P圜harm 2020.1 (Community Edition). There are many ways to write a Caesar cipher script in Python this tutorial goes over a script I wrote that works for me. Now that we have some basic knowledge of Caesar ciphers, let's get started on creating our encoder and decoder in Python! I've opted for Python 3.8 in this tutorial. There's no practical security use for Caesar ciphers they do not provide confidentiality or integrity of messages. Shifting the alphabet by 13 using a Caesar shift is also referred to as ROT13. For example, a Caesar cipher that shifts the alphabet by 13 means that A becomes N, B becomes O, C becomes P, and etc. A Caesar cipher is a method for encoding a message where letters of the alphabet are shifted, thus obfuscating the original message.
