WebWe can hack the Caesar cipher by using a cryptanalytic technique called brute-force. A brute-force attack tries every possible decryption key for a cipher. Nothing stops a cryptanalyst from guessing one key, decrypting the ciphertext with that key, looking at the output, and then moving on to the next key if they didn’t find the secret message.
