Question 1

What is HMAC-SHA512 seed generation?

Accepted Answer

HMAC-SHA512 is a military-grade cryptographic hash function that combines multiple entropy sources (system randomness, user bio-entropy, timestamps, and optional server seeds) to produce a highly secure 64-character hexadecimal seed. This method is widely used in provably fair gaming systems.

Question 2

Why use QR code output instead of clipboard copy?

Accepted Answer

Clipboard-hijacking malware can silently replace copied text with attacker-controlled values. By scanning a QR code with your phone, you completely bypass the computer clipboard, eliminating this attack vector.

Question 3

What is bio-entropy and why does it matter?

Accepted Answer

Bio-entropy refers to randomness derived from human physical actions, such as random keyboard input. Unlike machine-generated pseudo-random numbers, bio-entropy introduces true physical chaos that is impossible for software to predict or reproduce.
