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.
It uses a key to create a grid of letters that is then used to encode 2 letters at a time. It is a simple form of 16-bit encryption.
