Frequently Asked Questions

What does RNG stand for?

RNG stands for Random Number Generator, a system that produces unpredictable numerical sequences for various applications including gaming, cryptography, and statistical analysis.

What is the difference between true RNG and pseudo-RNG?

True RNG uses physical phenomena for randomness while pseudo-RNG uses mathematical algorithms. Our tool offers both JavaScript Math.random (pseudo-RNG) and cryptographically secure options.

When should I use cryptographically secure RNG?

Use cryptographically secure RNG for passwords, security tokens, encryption keys, or any application where predictability could pose security risks.

How many random numbers can I generate at once?

You can generate up to 100 random numbers in a single operation. For larger datasets, you can run multiple generations and combine the results.

What's the difference between standard and cryptographic RNG modes?

Standard mode uses JavaScript's Math.random() which is fast and suitable for games and general use. Cryptographic mode uses crypto.getRandomValues() which is slower but provides cryptographically secure randomness for security applications.
