Privacy & Security

Privacy and security tools require a higher standard of trust than most utilities — you're entering passwords, keys, hashes, and personal identifiers. NoxaKit's Privacy & Security collection is built on one principle: nothing leaves your browser. Every hash, every encryption, every password generation runs using the browser's native Web Crypto API without any server involvement.

**Who uses these tools?** Developers use AES encrypt/decrypt, RSA key pair generation, HMAC and PBKDF2 tools for local crypto operations. Security engineers use SHA-256 file hashing, bcrypt testing, and the password entropy estimator. Privacy-conscious individuals use the strong password generator, EXIF remover, and privacy blur tool. DevOps teams use the security headers checker and subnet calculator. Students and educators use the cipher tools (Caesar, Vigenère, Atbash) for cryptography coursework.

**Why the browser-only model is non-negotiable here** Server-based password tools, hash generators, and encryption utilities require you to trust that the server discards your input after processing. With NoxaKit's security tools, there is nothing to trust — the code runs locally, and you can inspect the browser's network tab to verify that no request is made.

**Common workflows** Secure password: generate a strong password → check its entropy → copy to clipboard — nothing is ever transmitted. File integrity: open SHA-256 file hasher → drop any file → copy the hash — the file bytes never leave your machine. API key hashing: open HMAC-SHA-256 → enter key and message → generate auth token — the key stays local.

**Subcategories** Password & Credentials covers password generation, entropy estimation, and pattern checking. Data Privacy Helpers includes PII redaction, EXIF removal, and privacy blur. Cryptography Utilities covers AES, RSA, SHA-256, HMAC, PBKDF2, and bcrypt. Web Security Checkers includes security headers, WCAG contrast, and HTTP header inspection. Identity & Anonymity covers browser fingerprinting info, IP checker, and user-agent parser.
