Generate a JSON Web Token (JWT) online by defining custom header values, payload claims, and signing algorithms.
This JWT Generator runs completely in your browser and does not transmit secrets or private keys. It is commonly used to create JWTs for testing authentication, authorization, and API security workflows.
100% Client-Side Execution. No Data Sent to Server Secure
Generate a signed JWT using custom headers and claims for testing authentication and authorization flows.
Decode a JSON Web Token to instantly view its header and payload. No secret or private key is required.
Validate a JWT by verifying its signature and checking registered claims such as expiration and not-before.
All processing happens locally using the browser’s WebCrypto API. Your tokens and keys are never sent to any server, making this tool safe for debugging production JWTs.
A JSON Web Token (JWT) is a compact, URL-safe means of representing claims to be transferred between two parties. It consists of three parts: Header, Payload (claims), and Signature.
JWTs are widely used for API authentication, single sign-on (SSO), and securely transmitting information between client and server. Learn more at JWT.io and Auth0's JWT guide. You can also follow this tutorial to implement the JWT based auth mechanism in spring boot.
JWT generation is the process of creating a token by defining its header, payload, and cryptographic signature. Generated tokens are commonly used for testing secured APIs and identity flows.
A JWT is generated by encoding the header and payload, then signing them using a cryptographic algorithm such as HMAC or RSA.
Generated tokens can be inspected using a JWT decoder and validated using a JWT validator.
JWT generation is secure when keys are handled responsibly. This tool performs token generation entirely in the browser and does not transmit sensitive data externally.
Use secure cryptographic algorithms and protect private keys generated using RSA or ECC.
A JWT generator creates signed JSON Web Tokens using custom claims and cryptographic signing algorithms.
Common algorithms include HMAC, RSA, and ECC-based signing methods.
Yes. JWT generators are commonly used to test authentication and authorization flows.
It is safe when generation occurs locally. This tool runs entirely in the browser and does not send data to any server.
