Weak passwords remain the leading vulnerability in cybersecurity breaches. Generating high-entropy passwords using proper cryptographic primitives protects user accounts against brute-force dictionary attacks.
Why Math.random() Is Unsafe for Security#
Standard Math.random() in JavaScript is a pseudo-random number generator (PRNG). It is not cryptographically secure and its internal seed state can be predicted by attackers.
// UNSAFE for passwords or security keys:
const unsafeRandom = Math.random();
// SECURE - Cryptographically Strong Pseudo-Random Number Generator (CSPRNG):
const array = new Uint32Array(1);
window.crypto.getRandomValues(array);
console.log(array[0]);
Cryptographic Standard
The Ilustrado Labs Password Generator exclusively uses browser-native crypto.getRandomValues() to guarantee maximum entropy and unguessable keys.
