WebFeb 25, 2024 · For example, the text “hello world” with the key “go” will be encoded as follows: Original text: Key: Encrypted text: To decipher this message you just need to have the secret key and do the reverse decipherment, using a subtraction. Although this encryption is much more secure than Caesar’s encryption, it can still be easily broken. WebYou need a cipher, specifically a Vigenere Cipher.
