Class JwkTokenStore

java.lang.Object

org.springframework.security.oauth2.provider.token.store.jwk.JwkTokenStore

All Implemented Interfaces:

TokenStore

public final class JwkTokenStore
extends Object
implements TokenStore

A TokenStore implementation that provides support for verifying the JSON Web Signature (JWS) for a JSON Web Token (JWT) using a JSON Web Key (JWK).

This TokenStore implementation is exclusively meant to be used by a Resource Server as it's sole responsibility is to decode a JWT and verify it's signature (JWS) using the corresponding JWK.

NOTE: There are a few operations defined by TokenStore that are not applicable for a Resource Server. In these cases, the method implementation will explicitly throw a JwkException reporting "This operation is not supported".

The unsupported operations are as follows:

• storeAccessToken(OAuth2AccessToken, OAuth2Authentication)
• removeAccessToken(OAuth2AccessToken)
• storeRefreshToken(OAuth2RefreshToken, OAuth2Authentication)
• readRefreshToken(String)
• readAuthenticationForRefreshToken(OAuth2RefreshToken)
• removeRefreshToken(OAuth2RefreshToken)
• removeAccessTokenUsingRefreshToken(OAuth2RefreshToken)
• getAccessToken(OAuth2Authentication)
• findTokensByClientIdAndUserName(String, String)
• findTokensByClientId(String)

This implementation delegates to an internal instance of a JwtTokenStore which uses a specialized extension of JwtAccessTokenConverter. This specialized JwtAccessTokenConverter is capable of fetching (and caching) the JWK Set (a set of JWKs) from the URL supplied to the constructor of this implementation.

The JwtAccessTokenConverter will verify the JWS in the following step sequence:

1. Extract the "kid" parameter from the JWT header.
2. Find the matching JWK with the corresponding "kid" attribute.
3. Obtain the SignatureVerifier associated with the JWK and verify the signature.

NOTE: The algorithms currently supported by this implementation are: RS256, RS384 and RS512.
