Caesar cipher can be broken easily using a known plaintext attack.
True
False
If you could encrypt a message of your choosing using the Caesar cipher, you would notice the 3 character shift easily. ***Edit: In a known plain text attack you have to have at least some of the plaintext and its corresponding cipertext. In a Caesar cipher you don't know the plain text, but you can easily brute force your way there by trying the limited combinations available. If anyone else agrees, change this to false. Edit: I agree!!! Edit: I'm not an author, but if you have a plaintext and a corresponding ciphertext - you can easly break every cipher. Caesar cipher is based on characters transposition. In my opinion correct answer is true (but I have to read this question 3 times before I checked an answer).
The answer has to be true - Caesar cipher shifts characters, if you have the plaintext and the cipher text not only do you know what the message is but now you can use it to determine how a Caesar cipher works thus you can work out how the algorithm works (Breaking it).
