How to Generate Securely
The best approach uses a cryptographically random source. Our tool uses crypto.getRandomValues() from the Web Crypto API the same API used by browsers for TLS key generation.
// Browser JavaScript (same as our tool)
const array = new Uint8Array(32);
crypto.getRandomValues(array);
const key = Array.from(array)
.map(b => b.toString(16).padStart(2, '0'))
.join('');
