Frequently Asked Questions

How does this random number generator create truly random numbers?

Our generator uses JavaScript's cryptographically secure random number generation (crypto.getRandomValues) combined with advanced algorithms to ensure true randomness and uniform distribution. Each number is generated independently with proper statistical properties, making it suitable for professional applications including security and research.

Can I generate large sequences of numbers at once?

Yes, the sequence mode can generate up to 100 numbers in a single operation. For larger datasets, you can generate multiple batches while maintaining proper randomness across all generations. Each batch is independent and maintains the same high-quality statistical properties.

What's the difference between lottery and sequence generation modes?

Lottery mode always generates unique numbers within the specified range (no duplicates), perfect for draws and selections. Sequence mode can optionally allow duplicates, making it ideal for statistical sampling and testing where repeated values are acceptable. Choose based on whether uniqueness is required for your application.

Is this random number generator suitable for cryptographic applications?

While we use cryptographically secure generation methods, this tool is designed for general-purpose applications like gaming, testing, and statistical work. For high-security cryptographic keys or critical security applications, use dedicated cryptographic libraries and hardware security modules specifically designed for that purpose.
