Integer Generator
Generate secure random integers within a specified range.
What is a cryptographically secure random number?
A cryptographically secure random number is generated using algorithms that produce unpredictable values suitable for security applications. Unlike Math.random(), secure generators use entropy sources like hardware noise. This generator uses the Web Crypto API for true randomness.
How do I generate random numbers for a lottery or raffle?
Set the minimum to 1 and maximum to your total entries, then generate one integer for each winner needed. For fair results, ensure no duplicate numbers are selected. This generator produces independent random values within your specified range.
Are the generated numbers truly random?
Yes, this generator uses cryptographically secure random number generation via the Web Crypto API. The numbers are as random as computer-generated numbers can be, suitable for security applications, games, simulations, and statistical sampling.
What's the difference between random and pseudo-random numbers?
Pseudo-random numbers (like Math.random()) follow deterministic algorithms that can be predicted if you know the seed. True/cryptographic random numbers use physical entropy sources and are unpredictable. This generator uses cryptographic randomness for maximum unpredictability.
