What term describes the science, art, and practice of breaking codes and ciphers?

• A. Cryptanalysis
• B. Encryption
• C. Hashing
• D. Key Length

Answer: (A)

Cryptanalysis is the science, art, and practice of breaking codes and ciphers. It focuses on uncovering hidden information without the key by exploiting weaknesses in cryptographic systems, from historic ciphers to modern algorithms. This differs from encryption, which is the process of turning plaintext into ciphertext to protect confidentiality; hashing, which creates a fixed, typically irreversible value for integrity purposes; and key length, which is a parameter that influences security but is not the act of breaking a cipher. So the term that best fits breaking codes and ciphers is cryptanalysis.
