Frequently Asked Questions

Are the security tools safe to use?

Yes, all security tools run entirely in your browser. Passwords, hashes, and UUIDs are generated locally using JavaScript and the Web Crypto API. Nothing is sent to any server.

How secure are the generated passwords?

Passwords are generated using the browser's cryptographically secure random number generator (crypto.getRandomValues), ensuring true randomness that's suitable for real-world use.

What hash algorithms are supported?

We support MD5 (using a JavaScript implementation), SHA-1, SHA-256, SHA-384, and SHA-512 (using the browser's native Web Crypto API for maximum security).
