In the simplest case this is just the user id like in the example above, but you can include other user information such as a username, user roles, permissions, etc. The payload is where you record any information that identifies the user. import jwtdecode from jwt-decode var token eyJ0eXAiO./// jwt token var decoded jwtdecode(token). You can use anything that can be serialized to a JSON dictionary as a payload. This is the information that you want stored in the token. The jwt.encode() function has three arguments of which the most important is the first, containing the token payload. '_jJKavmWrM6d_io5M5PBiK9AKMf_OcK4xpc17kvwI' > token = jwt.encode(, secret_key, algorithm='HS256')
> secret_key = "a random, long, sequence of characters that only the server knows" Encode or Decode JWTs Paste a JWT and decode its header, payload, and signature, or provide header, payload, and signature information to generate a JWT. After you verify that the user has provided the correct username and password, you can generate a token for the user: > import jwt Now let's say you want to create a token that gives a user with id 123 access to your application. decrypt and verify: after pasting in the encrypted JWT, if you are using an RSA algorithm, paste in your PEM-formatted (PKCS8) private key. The payload is encrypted, so it cannot be decoded without the private key. The header will be decoded and displayed in the appropriate box. Create a virtual environment, and install pyjwt in it: (venv) $ pip install pyjwt decode: paste in the encrypted JWT in the box on the left-hand side.
