Free Random Number Generator – True Cryptographic Random Numbers
The NexVaani Random Number Generator produces cryptographically random integers and decimals within any user-defined range. Ideal for contest giveaways, statistical sampling, tabletop dice rolling, and raffle drawings.
The NexVaani Random Number Generator generates random numbers using the browser-native crypto.getRandomValues() API for maximum entropy.

기술 아키텍처 및 실행 방식
Cryptographic Uniform Distribution
Numbers are generated by drawing random 32-bit unsigned integers from crypto.getRandomValues() and scaling via rejection sampling to eliminate modulo bias across [Min, Max].
Random_Int = Min + Math.floor((Crypto_Bytes / 0xFFFFFFFF) * (Max - Min + 1))기술적 제한 및 운영상의 제약
- Maximum sequence size per batch is 1,000 numbers.
주요 사양 및 기능
- Cryptographic Randomness – Uses W3C Web Crypto API for true entropy
- Custom Min/Max Range – Generate numbers between any two values (e.g. 1 to 100)
- Allow or Disallow Duplicates – Toggle unique number sequences
- Sorting Options – Sort output ascending, descending, or keep random order
자주 묻는 질문과 답변
Is this random number generator fair for giveaways and raffles?
Yes! It uses hardware-seeded cryptographic randomness (crypto.getRandomValues) rather than predictable pseudo-random algorithms.
Are my files uploaded, analyzed, or stored on NexVaani servers?
Where supported, tool inputs and files are processed locally inside your web browser using WebAssembly and HTML5 Canvas. Your files are not uploaded to NexVaani file-processing servers.
