Built for development workflows
Generate test tokens for local APIs, fixtures, and debugging without sending claims or signing secrets to a server.
JWT Generator
Create HS256, HS384, or HS512 JSON Web Tokens locally from JSON claims and a shared secret.
JWT generator
Create HMAC-signed tokens for development and testing.
Payload claims
HS algorithms use the same secret to sign and verify. Do not paste production secrets into shared devices.
HMAC scope
This tool intentionally supports symmetric HS algorithms. Public/private RSA and elliptic-curve key workflows are not mixed into the simpler shared-secret interface.
