How to learn cryptography the easy way with free online games

Ever wanted to crack mysterious codes like Alan Turing or send secret messages like Julius Caesar? If so, cryptography could be your next passion!

Discover more about cryptography and how to learn this fascinating skill.

Cryptography is a captivating and mysterious practice that’s helped shape events throughout history. And in today’s digital age, it’s still just as important!

By learning cryptography, you’ll discover how to create and break codes, explore tools and concepts to help crack passwords, find flaws in encrypted information, and see how information travels across the Internet.

Read on to discover how you can start learning cryptography at your own pace with CyberStart.

How to learn cryptography for free with CyberStart

You may be learning cryptography from scratch or perhaps you already have some understanding of the subject and want to deepen your knowledge further.

With CyberStart, you can try cryptography for yourself with hands-on, code-cracking challenges, or delve deeper into the theory to learn more about different methods of encryption and decryption.

Create your free CyberStart account to access fun cryptography challenges plus write-ups and video tutorials.

Learn real cryptography methods with CyberStart’s gamified challenges

It’s time to crack some codes! CyberStart has lots of gamified cryptography challenges for you to solve.

Let’s take a look at a challenge you can play right now!

Intern base L01 C02 - Mixed up Messages

“Mixed up Messages” is the perfect challenge to start on your cryptography learning adventure!

You don’t need any cryptography knowledge to solve this challenge, just an observational eye.

Too easy?

Let’s try a slightly more difficult challenge using a Caeser cipher. The Caesar cipher is one of the oldest forms of cipher and was named after the famous Roman general Julius Caesar, who used cryptography to send military messages.

HQ base L01 C07 - Secret Caesar

In this challenge, you’re investigating a suspicious cyber criminal gang’s documents, which may contain some secret information.

The brief tells us that we should try to use a Caesar cipher to crack the reference numbers. We are looking for a decrypted reference number containing the word BAR.

Don’t worry if you’ve never heard of a Caesar cipher before. The challenge brief tells us that in this type of cipher, the letters are shifted along by a certain offset, e.g. if the letter is A and the offset is two it will become C.

In this challenge, the offset is the order quantity.

Now you know what a Caesar cipher is, see if you can use it to decrypt the secret messages and find the flag.

There are plenty more fun cryptography challenges in CyberStart, but perhaps you also want to explore the theory of cryptography too.

Here’s how…

Strengthen your cryptography knowledge with CyberStart’s Field Manual

The Field Manual is created by cyber security experts and works hand-in-hand with CyberStart’s challenges to give you a better understanding of the techniques you learn in-game.
