What's in this suite
These tools handle your most sensitive material — identity scans, passwords, encrypted PDFs. Everything runs locally so the data is not just trustless-in-theory, it's trustless-in-fact: there is literally no server endpoint that could log your inputs even if we wanted to.
Common workflows
Common pairings: Aadhaar Masker + JPG to PDF for KYC uploads with masked first 8 digits. Password Generator + Protect PDF for sharing a confidential document with a unique password each time. Unlock PDF + Edit PDF when you need to mark up a password-protected contract you have legitimate access to.
Frequently asked
Quick answers about the privacy & security suite.
How private are the security tools really?
Fully private. The Aadhaar Masker, Password Generator, PDF Protect, and PDF Unlock all run client-side — there's no network round-trip with your input. You can verify with a network tab open: nothing is sent.
Are generated passwords secure?
Yes. The Password Generator uses `crypto.getRandomValues()`, the same cryptographically-secure source Node.js, OpenSSL, and modern browsers use for keys. There is no seed predictability and no fallback to `Math.random`.
Can I unlock a PDF I forgot the password to?
Only if you know or can guess the password — the Unlock PDF tool requires the existing password. It's not a brute-force tool, and we don't host one (that would be irresponsible). For your own forgotten passwords, try common patterns first, then a password manager search.
Is masked Aadhaar valid for KYC in India?
Yes. UIDAI explicitly endorses the masked format (first 8 digits hidden, last 4 visible). Most KYC processes — telecom, banking, mutual funds, rentals — accept it as the recommended way to share an Aadhaar copy.
