CompTIA Security+ (SY0-501) — Question 192

A company is planning to encrypt the files in several sensitive directories of a file server with a symmetric key. Which of the following could be used?

Answer options

• A. RSA
• B. TwoFish
• C. Diffie-Helman
• D. NTLMv2
• E. RIPEMD

Correct answer: B

Explanation

TwoFish is a symmetric key encryption algorithm, making it suitable for encrypting files. In contrast, RSA is an asymmetric algorithm, Diffie-Hellman is primarily used for key exchange, NTLMv2 is a authentication protocol, and RIPEMD is a hash function, none of which are appropriate for encrypting files directly.
