Cryptographically Secure Random Hex
This generator uses crypto.getRandomValues(), your operating system's cryptographically secure random source — far stronger than Math.random(). Each byte becomes two hex characters, so 16 bytes yields a 32-character string. It's ideal for API tokens, session IDs, nonces, and encryption keys. The value is generated on your device and never transmitted.
