JWT Signer
Enter Payload and secret to generate a signed JWT for easy test token creation. Supports HMAC (HS*), RSA (RS* / PS*), ECDSA (ES*); asymmetric algorithms allow one-click test key pair generation. All computation in-browser; keys are never uploaded.
For Testing Only
Do not enter production private keys here. Generated tokens can be verified with JWT Decoder or used with keys from JWK Generator.
How to Choose an Algorithm
For the difference between symmetric (HS*) and asymmetric (RS*/PS*/ES*) algorithms and their use cases, see JWT / JOSE documentation · Signature Algorithms.
