This cipher is very easy to learn and simple to encode or decode.
|

It just shifts the letters a certain number of spaces, i.e. for a shift of 3 a=d & x=a

#Vigenere Cipher
|
||||
This cipher is more complicated than a simple Caesar cipher.
|
||||
It uses an array of Caesar ciphers and cycles between them based on a key.
|
||||
This makes it more secure, but if you are not carful in your message or have a short key it will still output recognizable paterns that can be easily broken.

#Playfair Cipher
|
||||
This cipher is a little more complex.
|
||||
