  2. DSA

  3. HMAC

  4. RSA
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

RSA is the most widely used digital signature algorithm, providing both authentication and non-repudiation through asymmetric cryptography. DES is a symmetric encryption algorithm, not a signature algorithm. DSA (Digital Signature Algorithm) is specifically designed for digital signatures, but RSA is more common in practice. HMAC is a message authentication code using hash functions, not a digital signature algorithm. RSA is the correct answer based on widespread adoption.
