Security by Architecture

Zero Knowledge

Because we use the crypto.getRandomValues() API, the randomness is generated inside your browser's own memory space. The result never touches our servers.

True Randomness

Unlike Math.random(), our tools use hardware-seeded entropy pools, making them suitable for generating sensitive keys and passwords.

Frequently asked questions

Are these tools really free?

Yes. Every tool is free to use with no limits. We support the site through non-intrusive advertising.

Are the generated passwords secure?

Yes. Passwords are generated using cryptographically secure random values from your browser. They are never sent to any server or stored anywhere.

Do I need to create an account?

No. There is no sign-up, login, or registration. Just open a tool and start using it.

Do these tools work on mobile?

Yes. Every tool is fully responsive and works on phones, tablets, and desktops.

Is the randomness truly random?

Our tools use the browser's built-in cryptographic random number generator (crypto.getRandomValues), which provides cryptographically secure pseudo-random numbers suitable for security-sensitive applications.
