Generate OpenPGP keys (RSA or modern ECC) entirely in your browser. Add multiple user IDs, choose expiry, protect with a strong passphrase, and download public/private keys plus a revocation certificate.
Generate bcrypt hashes of passwords instantly in your browser. Choose salt rounds, copy the hash, and verify plaintext against hashed values. 100% secure, no data sent to server.
Inspect, decode, and validate JWT (JSON Web Token) strings instantly. Supports HS256 signature verification, live token decoding, and token generation — all in your browser.
Generate cryptographic hash digests using MD5, SHA-1, SHA-256, SHA-512, SHA3-256, SHA3-512, and RIPEMD160. Includes HMAC support with secret key. Everything runs securely in your browser.
Analyze the strength of a password based on length, complexity, and character variety. Includes real-time feedback and tips to improve security.
Create or inspect BIP39 passphrases entirely in your browser. Includes entropy/strength meter, Unicode NFKD normalization, RNG choices (WebCrypto or dice/coin), clipboard auto-clear, panic wipe, custom wordlists, and optional mnemonic → seed derivation (PBKDF2-HMAC-SHA512). Offline by default for privacy and speed. Use at your own risk; prefer air-gapped devices for real funds.
Encrypt or decrypt text and files locally using AES-256-CBC with PBKDF2 (SHA-256) key derivation and HMAC-SHA256 integrity (encrypt-then-MAC). Per-message salt & IV, configurable iterations, JSON envelope export, and OpenSSL legacy (Salted__) compatibility. Zero data upload, no recovery if the password is lost.
Tired of bloated tool websites with 10 ads per click? This platform is built for speed, simplicity, and reliability. Whether you're debugging JSON or testing colors, we’ve got your back.
