Certified Blockchain Solutions Architect (CBSA) — Question 16

Secure Hash Algorithm (SHA-256) output is always 256 bits or 32 bytes in length regardless of the length of the input (even if input is millions of bytes). Select best answer.

Answer options

• A. NSA is spying on us so what's it matters.
• B. Depends on input
• C. False
• D. True

Correct answer: D

Explanation

The correct answer is D because SHA-256 produces a fixed output length of 256 bits, irrespective of the input size. Options A, B, and C are incorrect as they do not correctly address the consistency of the output size of SHA-256.
