WebHow to attack the encryption with Ciphertext-Only-Attack These are the steps: Break a huge corpus in the target language into parts with almost the same size as the original plaintext should be. Encode these parts into Base64. Calculate the frequency table for each of 4 n, 4 n + 1, 4 n + 2, 4 n + 3 positions using the encoded corpus. WebThere are five general types of cryptanalytic attacks:- 1. Ciphertext-only attack: In this type of attack, the cryptanalyst has a series of cipher texts encrypted using the same encryption algorithm. Then, the cryptanalyst deduces the plain text of each of the cipher texts or identifies the key used to encrypt the cipher text 2.
