Free Security Tools - Run Locally in Your Browser

Security tools have a basic trust problem: if you generate a password on a site that logs everything you type, you have not generated a secure password. Our security tools run entirely in your browser. Nothing is sent to any server, nothing is logged, and you can confirm this by disconnecting from the internet after the page loads. The tool still works because the cryptographic primitives (Web Crypto API, JavaScript random sources) are built into your browser itself.

Indian users face specific password and identity threats: the "name@123" pattern is one of the most common weak password formats in India and gets cracked in seconds during credential-stuffing attacks against banking portals, EPFO, income tax e-filing, and DigiLocker accounts. A strong password generator and a hash verifier are basic defences worth using before anything sensitive.

When to use which tool

• Password generator: creating a fresh strong password for net banking, UPI app passcodes, EPFO portal, e-filing portal, or any account that holds money or KYC data
• Hash generator: verifying that a downloaded file (Aadhaar PDF, software installer, ISO image) has not been tampered with by comparing its SHA-256 against the publisher's checksum
• File integrity checks: confirming that a file you sent over WhatsApp or email arrived intact, by comparing hashes on both ends
• Hash comparisons in dev work: deduplicating files, verifying API request signatures, generating commit-style fingerprints

What makes a strong password in 2026

Length matters more than complexity. A 16-character random password takes longer to brute-force than a 10-character password with every special character available. Avoid patterns based on your name, date of birth, mobile number, or city. Avoid reusing passwords across banking, email, and government portals. A password manager that generates and stores per-site random passwords is the practical answer; the password generator below produces strings suitable for that workflow.
