Question

Most ciphers need a key, like how the Caesar cipher needs a number or the Vignere cipher needs a word. But let's say you didn't have that, then what would you do? I guess an easier way to say it would be 'How do you crack a cipher without a key?" Also, please try not to copy-paste from sites, but if you do, at least cite the source. Thanks in advance

Answer 1

Explanation:

A key must be selected before using a cipher to encrypt a message. Without knowledge of the key, it should be extremely difficult, if not impossible, to decrypt the resulting ciphertext into readable plaintext..
