What are two functions of secret key cryptography? (Choose two.)
The correct answer is A. key selection without integer factorization D. utilization of less memory. Secret key (symmetric) cryptography uses the same key for encryption and decryption, often involves algorithms that do not rely on integer factorization, and typically consumes less memory than asymmetric methods.

Why each option
Secret key (symmetric) cryptography uses the same key for encryption and decryption, often involves algorithms that do not rely on integer factorization, and typically consumes less memory than asymmetric methods.
Secret key cryptography algorithms, like AES, do not rely on the computational difficulty of integer factorization, which is a principle behind some asymmetric algorithms like RSA.
Secret key cryptography utilizes the *same* key for both encryption and decryption, not different keys.
The utilization of large prime number iterations is characteristic of asymmetric (public-key) cryptography, particularly algorithms like RSA.
Secret key (symmetric) algorithms are generally computationally less intensive and require less memory and processing power compared to asymmetric algorithms for the same level of security.
Secret key cryptography requires the key to be known on *both* sides (sender and receiver) for encryption and decryption.
