🔐 Security & Cybersecurity Tools
12 free tools for password security, text encryption, file hashing, and cybersecurity inspection. All cryptographic operations use the browser's native Web Crypto API.
🔐 Security Tools
Generate and evaluate passwords and PINs using cryptographically secure randomness. Understand entropy, detect breach patterns, and produce memorable passphrases — all locally in your browser.
Password GeneratorCryptographically secure passwords via
crypto.getRandomValues() with rejection sampling. Full charset control, exclusions, bulk output, session history.Web Crypto API
Passphrase GeneratorMemorable multi-word passphrases from a curated wordlist. Choose word count, separator, case style, and optional number/symbol append.Web Crypto API
Password Strength CheckerMulti-factor analysis: Shannon entropy, keyboard walk detection, leet-speak, date patterns, and crack time estimates at four attack speeds.RegExp engine
Password Entropy CalculatorCalculate precise Shannon entropy (H = L × log₂N) with full formula display, charset breakdown, and comparison against common password types.Math API
PIN GeneratorCrypto-random PINs in numeric, alphanumeric, hex, and grouped formats. Checks against 200 most-common PINs with configurable constraints.Web Crypto API
Breach Pattern CheckerLocally detect 15+ breach-risk patterns including keyboard walks, leet substitutions, date patterns, and dictionary words. Zero API calls.RegExp engine
🛡 Cybersecurity Tools
Encrypt data, generate cryptographic hashes, inspect browser fingerprints, and analyse HTTP headers. All heavy lifting is done by the browser's built-in Web Crypto and Canvas APIs.
AES Text EncryptorAES-256-GCM encryption with PBKDF2-SHA256 key derivation (310,000 iterations). Authenticated encryption — tampering detected on decryption.Web Crypto API
SHA Hash GeneratorSHA-1/256/384/512 hashing via
crypto.subtle.digest(). Includes HMAC-SHA256/384/512 signing and hash comparison tab.Web Crypto API
File Hash GeneratorHash any file with SHA-256/512/384/1. Verify integrity by pasting an expected checksum — instant match or mismatch detection per file.Web Crypto API
Browser Fingerprint CheckerRead 30+ fingerprinting signals including canvas pixel hash, WebGL renderer, screen resolution, timezone, and CPU cores. Uniqueness estimate.navigator API
HTTP Headers Parser & ExplainerPaste raw HTTP response headers and get plain-English explanations, security score, missing-header warnings, and cookie attribute flags.Client-side only
IP Address Privacy CheckerFetch your public IP from ipify.org and analyse what it exposes — geolocation precision, ISP, IPv4/IPv6 structure, and privacy risk.ipify.org API
