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.
Can you figure out what the message says? Register for free in just one minute to play this challenge.
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.
