Frequently Asked Questions
Explore comprehensive answers, technical specifications, and security guidance for auditing and safeguarding your documents.
Are these security tools safe to use?
Yes, absolutely. All tools on this page operate entirely client-side. This means your data is processed within your own browser and is never sent to our servers or any third parties.
Can I use these tools offline?
Once the page is loaded, the tools can function without an active internet connection since all logic is handled locally by JavaScript.
Is the Password Generator truly random?
Yes, our password generator uses cryptographic-grade random number generation (Web Crypto API) to ensure your passwords are mathematically secure and unpredictable.
