When explaining a Hash Generator in a public forum, use a known test string or a small synthetic file. State the exact bytes or text encoding, selected algorithm, and resulting digest so others can reproduce it. Do not use passwords, API keys, or real private documents as examples; hashing them does not make disclosure safe. If comparing two outputs, show the full digests and explain whether the input, algorithm, or encoding differed. A reproducible harmless example teaches more than a redacted secret.
