Feature request: -j flag for encoding using the output of decode -j

[nnsee]

decode allows supplying the -j (--json) flag to output JSON in the following format:

{
  "header": {
    "typ": "JWT",
    "alg": "HS256"
  },
  "payload": {
    "exp": 1835241013,
    "iat": 1635240113,
    "sub": "2e5c4600-9fb6-47b4-aff7-f490d23c6074",
    "email": "[email protected]"
  }
}

I propose adding a -j (--json) flag to encode as well which accepts JSON in the same format. That means, options such as typ, alg etc. should be inferred from the header object, as well as payload and so on.

Ideally, this should enable the following workflow:

echo $JWT | jwt decode -j - | modify-token | jwt encode -j -S secret-key -

... where modify-token can be replaced with whatever utility that modifies the JSON.

@neonSea This is a pretty neat idea, however I'll need to think about this a bit more. The problem here is that a flag of -j or --json would conflict with the name and idea of the last argument, which allows the payload to be a json string.
