100% Fair & Truly Random
We use cryptographically secure random number generation to guarantee every selection is completely fair and unpredictable.
How Our Randomness Works
Unlike simple random functions, we use the Web Crypto API's crypto.getRandomValues() method, which provides cryptographically strong random values. This is the same technology used by banks and security systems.
Cryptographically Secure PRNG
Our tools use CSPRNG (Cryptographically Secure Pseudo-Random Number Generator) which is designed to be unpredictable even if previous outputs are known. This ensures no one can predict or manipulate the results.
100% Local Processing
All randomization happens directly in your browser. No data is sent to any server, making it impossible for anyone (including us) to influence the outcome.
Equal Probability
Every entry in your list has exactly the same mathematical probability of being selected. We use uniform distribution algorithms to guarantee fairness.
Zero Manipulation
Since everything runs locally and uses cryptographic randomness, there is no way for anyone to rig or influence the results. What you see is what you get.
Technical Details
For developers and technically curious users, here's exactly how we generate random selections:
// Using crypto.getRandomValues() for secure randomness
function secureRandom(max: number): number {
const randomValues = new Uint32Array(1);
crypto.getRandomValues(randomValues);
return randomValues[0] % max;
}
// Select a random item from an array
const randomIndex = secureRandom(items.length);
const winner = items[randomIndex];This code uses the browser's built-in cryptographic random number generator, which sources entropy from hardware-level unpredictable events.
