Webof cryptography. We call the act of testing all 25 options until nding the key, the method of brute force. However, even if we couldn’t use brute force the Caesar cipher is still considered to be weak. This is because each letter of the alphabet (say \a") always gets encrypted to the same letter (which depends on your shift).
