The Vigenere cipher is a great example of a more advanced type of substitution cipher. It takes the idea of the Caesar Cipher and makes it a lot more difficult to decrypt by combining multiple Caesar Cipher substitutions and shifts into a single encrypted text. <\/p>\n\n\n\n

There are 2 ways to encrypt and decrypt a Vigenere Cipher:<\/p>\n\n\n\n

Method 1 is by using a grid<\/p>\n\n\n\n

Method 2 is by using a Caesar cipher wheel <\/p>\n\n\n\n

Below we have some resources to help tell you more about the cipher and also some encryption and decryption exercise using the Vigenere cipher with our online Caesar Cipher Wheel <\/p>\n\n\n\n
