WebTypes of cryptanalysis There are three generic types of cryptanalysis, characterized by what the cryptanalyst knows: (1) ciphertext only, (2) known ciphertext/plaintext pairs, and (3) chosen plaintext or chosen ciphertext. WebClassifying encryption methods In modern cryptology, a distinction is made between symmetric and asymmetric encryption methods. This classification is based on key handling. With symmetric cryptosystems, the same key is used both for the encryption and the decryption of coded data.
