WebCryptanalysis: Cryptanalysis is the process of breaking codes to decipher the information encoded. Cryptography: Cryptography is the science of encoding messages. This is the most secure method to transmit a message over insecure channels. Cryptology is as old as writing itself but only emerged as a scientific field in the 19th century. WebCryptanalysis of classical ciphers. Classical ciphers are commonly quite easy to break. Many of the classical ciphers can be broken even if the attacker only knows sufficient ciphertext and hence they are susceptible to a ciphertext-only attack. Some classical ciphers (e.g., the Caesar cipher) have a small key space.
