# Simple Ciphers

One of the earliest encryption methods, Ciphers, were used to encrypt plaintext into something called ciphertext.\
&#x20;The simplest way to do this would be to use a **Caesar Cipher**.\
&#x20;Named after Julius Caesar, Caesar encrypted his messages with this cipher, making messages seem like gibberish to the normal eye, but very easy to decrypt.\
&#x20;Anyways, enough with the caesar cipher history lesson, let's move on to other ciphers.

A **Vigenère cipher** uses what a Caesar Cipher built a basis on, except an alphanumerical key is used.\\

* Caesar cipher only has 26 usable values, `1-26`

This makes the Vigenère cipher a lot harder to crack.\
&#x20;These further advancements lead to much stronger encryption, making messages harder to crack, due to an increase in the number of charcters used to encode / encrypt the messages.

This Vigenere cipher was also used in this [writeup from DawgCTF 2020](https://github.com/TheWinRaRs/References/blob/master/Crypto).
