Certified Blockchain Solutions Architect (CBSA) — Question 14

SHA-1 is the most commonly used SHA algorithm, and produces a ______-byte hash value(size).

Answer options

• A. 256
• B. 128
• C. 32
• D. 20

Correct answer: D

Explanation

The correct answer is D, as SHA-1 produces a 20-byte hash value. The other options are incorrect because SHA-256 generates a 32-byte hash, SHA-128 does not exist, and 32 bytes does not match the output of SHA-1.
