JWT Verify (HS256) Verify a JWT's HMAC-SHA256 signature using your secret — locally, so the secret never leaves your browser. JWT Builder (HS256) Create and sign a JWT with HMAC-SHA256 — handy for generating test tokens. Signing happens locally. Hash (SHA) Compute SHA-1/256/384/512 hashes using the Web Crypto API, entirely on your device. Base64 Encode/Decode Encode/decode Base64 with full UTF-8 support (works correctly with any language). Password / Token Generate strong passwords and secret tokens (API keys, NEWS_INGEST_TOKEN, etc.) using secure crypto — nothing leaves your browser.
