Generate random numbers in any range using the browser's crypto source, with no-repeat and sort options.

Up to 10,000.
Numbers come from your browser's cryptographic random source with rejection sampling, so every value in the range is equally likely.
About Random Number Generator
Set a min, max, and count and get uniformly distributed integers from your browser's cryptographic random source. Rejection sampling removes the subtle bias naive modulo tricks introduce, a no-repeats toggle draws without replacement (great for raffles), and a sort toggle orders the output.
Common uses
- Draw raffle or giveaway winners fairly
- Pick random samples for testing or review
- Generate lottery-style unique number sets
Example
Input
Min 1, max 90, count 5, no repeats

7, 23, 41, 58, 86
