🔑 JWT Generator
Generate signed JWT tokens for testing. HS256/HS384/HS512. ⚠️ For testing only — never expose real secrets in browser tools.
⚠️ Security note: Signing happens client-side in your browser. Don't paste production secrets here. Use this for development/testing only.
Note: HS384 not natively supported by Web Crypto, falls back to HS256
⚠️ 19/32 — too short for HS256 in production
