常见问题
Is this truly random?+
Yes. The generator uses the Web Crypto API (window.crypto.getRandomValues) for cryptographically secure pseudo-random number generation. This is the same source of randomness used for encryption keys and is considered unpredictable.
Can I use this for lottery or raffle drawings?+
The randomness quality is suitable for fair drawings. However, for official lotteries or legally binding random selections, you may need a certified random number generator with auditable records.
