Certified Ethical Hacker (CEH v10) — Question 5

Which of the following Secure Hashing Algorithm (SHA) produces a 160-bit digest from a message with a maximum length of (264-1) bits and resembles the MD5 algorithm?

Answer options

• A. SHA-2
• B. SHA-3
• C. SHA-1
• D. SHA-0

Correct answer: C

Explanation

SHA-1 is the correct answer because it produces a 160-bit hash and is indeed similar in structure to MD5. SHA-2 and SHA-3 create longer hashes, while SHA-0 is an outdated version that has been largely replaced by SHA-1 due to security vulnerabilities.
