FAQ

Security Tools: common questions

What belongs in Security Tools on Toolspire?

Security Tools is one collection on justtools.info. Open any tool and the page tells you whether the work stays on your device or a public lookup is required.

Are generated passwords stored anywhere?

No. Passwords are generated with your browser’s cryptographically secure random number generator and exist only on your screen.

What does the SSL checker send?

Only the domain name you enter, to public certificate-log and DNS services, plus an HTTPS request from your browser to the site. Nothing is stored.

Which randomness source is used?

The Web Crypto API (crypto.getRandomValues), the same source browsers use for encryption keys.
