Small checks.
Safer digital lives.
Spot suspicious links, test password strength, and verify file fingerprints — privately, right in your browser.
Choose a security tool
Real checks, simple explanations, no sign-up.
Your security, made easier.
A thoughtful toolkit for everyday digital decisions — with nothing complicated to set up.
Choose your check
Open any tool and enter a sample link, password, or local file.
Understand the result
Clear explanations show what was checked and what a result does not prove.
Keep control
Sensitive input stays in your browser; you decide what to share.
No logins, no file uploads, and no server-side password checks. Only checklist progress and language preference are saved in this browser.
Check a suspicious link
Before opening a website, look for common warning signs. This check works entirely in your browser and never visits the link.
Paste a website address
Example: https://example.orgReady when you are
Enter a link to see a risk estimate and clear reasons behind it.
The result is a simple heuristic based on how the URL looks. A link with no warnings can still be dangerous. Never enter passwords on sites you do not trust.
Build stronger passwords
Explore how length, variety, and predictable patterns affect password strength. For classroom demos, use invented passwords, not your actual secrets.
Try a sample password

Type an invented password to get immediate, local feedback.
This tool does not check leaked-password databases. Choose long, unique passwords and turn on multi-factor authentication wherever possible.
Verify a file fingerprint
Calculate a file's SHA-256 hash in your browser. Compare the result with a trusted hash to detect accidental or unwanted changes.
Choose a file
Your file stays on this deviceNo fingerprint yet
Select a file, then calculate its SHA-256 hash.
Compare only against a fingerprint from a trusted source. SHA-256 cannot tell whether a file contains malware.
