Caesar cipher is not very secure encryption key, even if one does not now the number of shifts being used. Since there are only 25 shifts when using the 26 methods, it is not so hard to use all the shifts and decrypt a message. What is the name of the method consisting of trying all possible encryption keys. A. Brute Fore Attack B. Decoding C. Substitution D. Decryption

The method consisting of trying all possible encryption keys is known as a brute force attack. In this approach, an attacker systematically checks all possible keys until the correct one is found, hence breaking the encryption. While it can be effective, it's often time-consuming and impractical for more complex encryption methods. In the case of the Caesar cipher, the limited number of possible shifts makes it particularly vulnerable to this type of attack. With just 25 possible shifts, an attacker can quickly decipher even encrypted messages, showcasing the importance of using more sophisticated encryption techniques for sensitive information.
