Details
JSON Web Token (JWT) is an open standard defined in RFC 7519 for a compact and self-contained way for securely transmitting information between parties using a JSON object.
Information in JWTs can be verified and trusted because it is digitally signed using a secret (with the HMAC algorithm) or a public/private key pair using RSA or ECDSA.
This tool will generate a random secret key for you to use in your JWTs for HMAC signing and verification using your browser's crypto module. The secret key will be generated with the length you specify in bits.
The secret won't be transmitted anywhere. You should copy it and store it securely in a vault or your application's secrets storage.
