How Our Random Number Generator Works
Our random number generator employs sophisticated algorithms to produce high-quality pseudo-random numbers. Here's what makes our generator reliable:
π Cryptographic Quality
We use the browser's built-in cryptographically secure random number generator (crypto.getRandomValues()) when available, ensuring high-quality randomness suitable for most applications.
β‘ Client-Side Processing
All number generation happens in your browser, ensuring privacy and eliminating server dependencies. Your generated numbers are never transmitted or stored on our servers.
π― Uniform Distribution
Our algorithms ensure that all numbers within your specified range have an equal probability of being selected, providing truly unbiased results.
π No Patterns
Advanced seeding techniques prevent predictable patterns, making each generation session independent and unpredictable.
Frequently Asked Questions
Is this random number generator truly random?
Our generator uses pseudo-random algorithms that produce statistically random results suitable for most applications. While not truly random in the mathematical sense, the results are unpredictable and uniformly distributed.
Can I use this for cryptographic purposes?
While we use cryptographically secure methods when available, we recommend using dedicated cryptographic libraries for security-critical applications. Please review our disclaimer for more information.
Are my generated numbers stored anywhere?
No, all number generation happens locally in your browser. We do not store, transmit, or have access to the numbers you generate.
What's the maximum range I can use?
You can generate numbers within the range of -999,999,999 to 999,999,999, and generate up to 1,000 numbers at once.
Can I generate numbers without duplicates?
Yes! Simply uncheck the "Allow Duplicates" option, and our generator will ensure all numbers in your set are unique.
