Security Tools & Calculators
Free, practical tools to stay safe online — check and generate strong passwords, estimate breach cost, spot phishing links, verify file integrity, and learn what network ports do. Everything runs privately in your browser.
Password Strength Checker
See how strong a password really is — its entropy, a Very Weak to Very Strong rating, and how long it would take to crack. Runs entirely in your browser; nothing is sent to a server
Secure Password Generator
Generate long, random passwords with a cryptographically-secure generator. Choose the length and character types and copy the result — created locally, never transmitted or stored
Data Breach Cost Calculator
Project what a breach could cost from records exposed, cost per record, and aggravating factors like regulation or poor response — a planning estimate built on industry-average figures
Phishing URL Checker
Paste a suspicious link to flag phishing warning signs — raw IP addresses, look-alike tricks, suspicious TLDs, and credential keywords. The link is analyzed in your browser, never visited
File Hash Generator
Compute the SHA-256, SHA-1, or SHA-512 checksum of any text or file to verify integrity and detect tampering — hashed in your browser via Web Crypto, with nothing uploaded
Port Scanner Simulator
Look up what runs on a TCP/UDP port and the risk of exposing it — SSH, HTTP, HTTPS, RDP, SMB and more. An educational reference that performs no real scanning and connects to no host
