About

InfraHub Toolkit puts 9 essential developer and network security tools in your Chrome toolbar — instant access, no new tab, no sign-up, no API keys, no data ever leaves your browser.

The full web app with 25+ tools is available free at https://infrahub.ninja

🛠 THE 9 TOOLS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🌐 MY PUBLIC IP INSPECTOR
Instantly see your public IPv4 and IPv6 address, ISP name, ASN number, city, country (with flag), and timezone. Auto-refreshes every time you open the extension. Essential for VPN verification, network debugging, and ISP routing checks.

🔐 PASSWORD GENERATOR
Generate cryptographically secure passwords using crypto.getRandomValues() — the browser's OS-seeded entropy source. Customize length (4–64 chars), character sets (uppercase, lowercase, digits, symbols), and see real-time entropy strength score. Passwords never touch a server.

🆔 UUID GENERATOR
Generate RFC 4122 UUID v4 (cryptographically random) and UUID v7 (millisecond-precision time-sortable, ideal for database primary keys) in batches of 6. Copy individually or copy all. Uses crypto.randomUUID() — no third-party libraries.

{ } JSON FORMATTER & MINIFIER
Paste raw API response JSON and instantly format it with 2-space indentation for readability, or minify it for transmission. Real-time syntax error detection with line/column indicators. Auto-formats on paste.

📄 BASE64 ENCODER / DECODER
Encode or decode Base64 with full UTF-8 support. Toggle between standard (RFC 4648 §4) and URL-safe (RFC 4648 §5, replaces + with - and / with _) variants. Perfect for API Authorization headers, data URIs, Kubernetes secrets, and JWT payload inspection.

🔑 JWT DECODER & INSPECTOR
Paste any JSON Web Token to instantly decode its header (algorithm, type) and payload (all claims). Shows whether the token is expired with exact time remaining or elapsed since expiry. Works entirely offline — your tokens never leave the extension.

🔍 URL SECURITY ANALYSER
Analyse any URL for 13 suspicious heuristic patterns — fully offline, zero network requests, zero API key. Detects: IP-as-hostname, high-risk TLDs (.xyz, .tk, .pw), URL shorteners, Punycode/homograph domains, brand names in subdomains (paypal.evil.com), phishing keywords (login, verify, secure), executable file extensions, double-extension tricks (.pdf.exe), and more. Each finding is colour-coded by severity with a risk score 0–100. One-click deep-scan buttons for VirusTotal (90+ AV engines), Google Safe Browsing Transparency Report, and URLhaus malware database.

# HASH GENERATOR
Generate SHA-256, SHA-512, and SHA-1 cryptographic hashes using window.crypto.subtle — the browser's native Web Crypto API, the same engine powering TLS. Hashes update in real time as you type. Supports hex output. No third-party libraries, no server calls.

⚠ UNICODE / NON-ASCII DETECTOR
Detect hidden threats in text and URLs: confusable characters (Cyrillic "а" that looks identical to Latin "a"), invisible zero-width joiners and non-joiners (ZWJ/ZWNJ), RTL override characters (used in phishing filenames), and IDN/Punycode spoofed domains. Critical for security engineers reviewing code, email headers, or suspected phishing URLs.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🛡 PRIVACY — 100% LOCAL PROCESSING
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Password, UUID, JSON, Base64, JWT, Hash, Unicode Detector → fully offline, zero network requests ever made.

My IP → fetches your public IP from api.ipify.org and ipapi.co only when you open the tab (standard public IP lookup, same as typing "what is my ip" in Google).

URL Analyser → 100% client-side heuristic analysis, no network requests. External scanner links (VirusTotal, etc.) open in a new browser tab — the extension itself makes no requests.

No accounts. No telemetry. No analytics. No ads. Your passwords, tokens, hashes, and code never leave your device.
