WebIn the shifted alphabet cipher or any simple randomized cipher, the same letter in the cipher replaces each of the same ones in your message (e.g. 'A' replaces all 'D's in the plaintext, etc.). The weakness is that English uses certain letters more than any other letter in the alphabet. 'E' is the most common, etc. WebThe Vigenère cipher works by using a keyword to select a series of different monoalphabetic ciphers. The keyword is used to select the cipher alphabet for each letter in the message. The Vigenère cipher is an example of a polyalphabetic cipher, as it uses multiple cipher alphabets to encrypt the message.
