Method Detail

build

public JwtProvider build()

Description copied from interface: Builder

Build the instance from this builder.

Specified by:

Returns:

instance of the built type

propagate

public JwtProvider.Builder propagate(boolean propagate)

Whether to propagate identity.

Parameters:

propagate - whether to propagate identity (true) or not (false)

Returns:

updated builder instance

authenticate

public JwtProvider.Builder authenticate(boolean authenticate)

Whether to authenticate requests.

Parameters:

authenticate - whether to authenticate (true) or not (false)

Returns:

updated builder instance

allowImpersonation

public JwtProvider.Builder allowImpersonation(boolean allowImpersonation)

Whether to allow impersonation by explicitly overriding username from outbound requests using JwtProvider.EP_PROPERTY_OUTBOUND_USER property. By default this is not allowed and identity can only be propagated.

Parameters:

allowImpersonation - set to true to allow impersonation

Returns:

updated builder instance

allowUnsigned

public JwtProvider.Builder allowUnsigned(boolean allowUnsigned)

Configure support for unsigned JWT. If this is set to true any JWT that has algorithm set to none and no kid defined will be accepted. Note that this has serious security impact - if JWT can be sent from a third party, this allows the third party to send ANY JWT and it would be accpted as valid.

Parameters:

allowUnsigned - to allow unsigned (insecure) JWT

Returns:

updated builder insdtance

verifySignature

public JwtProvider.Builder verifySignature(boolean shouldValidate)

Configure whether to verify signatures. Signatures verification is enabled by default. You can configure the provider not to verify signatures.

Make sure your service is properly secured on network level and only accessible from a secure endpoint that provides the JWTs when signature verification is disabled. If signature verification is disabled, this service will accept ANY JWT

Parameters:

shouldValidate - set to false to disable validation of JWT signatures

Returns:

updated builder instance

subjectType

public JwtProvider.Builder subjectType(SubjectType subjectType)

Principal type this provider extracts (and also propagates).

Parameters:

subjectType - type of principal

Returns:

updated builder instance

atnTokenHandler

public JwtProvider.Builder atnTokenHandler(TokenHandler tokenHandler)

Token handler to extract username from request.

Parameters:

tokenHandler - token handler instance

Returns:

updated builder instance

optional

public JwtProvider.Builder optional(boolean optional)

Whether authentication is required. By default, request will fail if the username cannot be extracted. If set to false, request will process and this provider will abstain.

Parameters:

optional - whether authentication is optional (true) or required (false)

Returns:

updated builder instance

outboundConfig

public JwtProvider.Builder outboundConfig(OutboundConfig config)

Configuration of outbound rules.

Parameters:

config - outbound configuration, each target may contain custom object JwtProvider.JwtOutboundTarget to add our configuration.

Returns:

updated builder instance

signJwk

public JwtProvider.Builder signJwk(Resource signJwkResource)

JWK resource used to sign JWTs created by us.

Parameters:

signJwkResource - resource pointing to a JSON with keys

Returns:

updated builder instance

verifyJwk

public JwtProvider.Builder verifyJwk(Resource verifyJwkResource)

JWK resource used to verify JWTs created by other parties.

Parameters:

verifyJwkResource - resource pointing to a JSON with keys

Returns:

updated builder instance

issuer

Issuer used to create new JWTs.

Parameters:

issuer - issuer to add to the issuer claim

Returns:
