Caesar Ciphers
Caesar ciphers are one of the earliest known and simplest ciphers we use in Cosykiller.
They are very common and it is probably one of the first ciphers you will have come in contact with as it’s often used in education to teach problem solving.
It is a type of letter substitution cipher in which each letter in the message is ‘shifted’ a certain number of places down the alphabet. For example, if you used A+1 then the letter A would be replaced by the letter B, and the letter B would become C, and so on.
Caesar ciphers are so easy, we often use them in conjunction with other ciphers just to make them more complex to solve.
Of course, what makes them even more tricky is when we use a language with shared lettering e.g. Egyptian Hieroglyphs where F and S share a symbol for instance (That’s a hint).
