  # ...
  firewalls:
    main:
      hallo_verden_jwt:
        provider: 'user_provider'
        failure_handler: ~
        token:
          key_set: 'my_key_set'
          jws_loader: 'hallo_verden_default'
          claim_checker: 'hallo_verden_default'
          mandatory_claims: []
          user_identifier_claim: 'sub'
          token_extractor: 'hallo_verden.token_extractor.bearer'

Key set (key_set)

You need to provide a key set.

See PHP JWT Framework for how to provide a key set.

JWS Loader (jws_loader)

There is a default JWS loader provided (hallo_verden_default), this loader is using the jws_compact serializer and supports RS256 and HS256 signature algorithms.

See PHP JWT Framework for how to create your own loader.

Claim checker (claim_cheker)

There is a default claim checker provided (hallo_verden_default), this checker checks the exp, iat and nbf claims.

See PHP JWT Framework for how to create your own checker.

Mandatory claims (mandatory_claims)

Here you specify the claims that need to be mandatory in your JWT. The user_identifier_claim is automatically added as a mandatory claim.

User identifier claim (user_identifier_claim)

This claim is sent to the user provider for retrieving the user.

Token extractor (token_extractor)

The default extractor hallo_verden.token_extractor.bearer get the bearer token from the authorization header. You can create your own extractor by implementing the TokenExtractorInterface and set the service id to this option.

Failure handler (failure_handler)

By default, the following response is sent on failure:

{
  "error": "INVALID_TOKEN"
}

You can modify this by creating a service implementing the AuthenticationFailureHandlerInterface and set the service id to this option.
