Security & Privacy Tools
Encryption, password, key, hash, checksum, redaction, and metadata privacy tools.
Most Used Tools
Ranked from tool metadata, popularity signals, and category relevance.
Cryptographic Hash Generator
Generate SHA-256, SHA-512, SHA-384, and SHA-1 hashes for files and text locally in your browser. Verify checksums with zero uploads, Web Crypto API support, Web Worker processing, and chunked large-file reading.
Cryptographic Secret Sharing Tool
Split a secret into secure M-of-N recovery shares with real Shamir Secret Sharing, or reconstruct it from the required threshold. Supports BIP39 seed phrases, keys, passwords, Base58/Hex/Base64 shares, QR codes, and offline recovery — entirely in your browser.
Large File Checksum Verifier
Verify file integrity by comparing local files against published MD5, SHA-1, SHA-256, SHA-384, and SHA-512 checksums. Multi-GB support with Web Worker processing, zero uploads, and automatic algorithm detection.
OpenPGP Message Encryptor
Encrypt, decrypt, sign, and verify messages using OpenPGP.js in your browser. Supports multi-recipient encryption, digital signatures, ASCII-armored output, and GnuPG-compatible keys with AES-256 and SHA-256.

Password Entropy Calculator
Check the mathematical entropy of any password or passphrase in your browser. Uses the Shannon formula L × log₂(R) to measure true password strength, detect weak patterns, estimate crack time, and compare Diceware passphrases — 100% client-side with zero uploads.
HKDF Key Derivation Tool
Derive cryptographic keys from a master secret using RFC 5869 HKDF (HMAC-based Key Derivation Function) in your browser. Supports SHA-256, SHA-384, SHA-512, configurable salt, info, and output length. Generate single or multiple derived keys instantly using the native Web Crypto API with zero server interaction.

About Security & Privacy Tools
Security & Privacy Tools consolidates the old photo/file privacy cluster with encryption, password, key, hash, checksum, redaction, and metadata workflows. If a task protects data, verifies integrity, removes sensitive metadata, or inspects hidden content, it belongs here.
This category removes the old split between privacy and security. It gives users one clear place to find EXIF cleaners, document metadata tools, file encryption, password generation, RSA keys, OpenPGP encryption, hash generation, and checksum verification.
This category currently includes 23 tools across 8 active subcategories. Add a new tool with the correct category and subcategory metadata, and this page updates automatically.
