WebJun 22, 2024 · Caesars shift takes one key, which is used to shift each character in the plaintext. This single key is the weakness of the cipher: once the correct shift is figured out, the whole message is revealed. Mathematically, this type of cipher can be written as a problem in modular arithmetic, which works with values wrapped up in a specific range. WebJun 11, 2012 · One of the earliest encryption methods is the shift cipher. A cipher is a method, or algorithm, that converts plaintext to ciphertext. Caesar’s shift cipher is known as a monoalphabetic substitution shift cipher. See Figure 7-1. Figure 7- 1: Monoalphabetic Substitution Shift Cipher
