JarCastingOAuth2 Server Library
OAuth2 Java Server Library is a backbone of OAuth2 provider which will provide basic OAuth2 support.
Please note: We take oauth2-server's security and our users' trust very seriously. If you believe you have found a security issue in oauth2-server library, please responsibly disclose by contacting us at [email protected].
Build Status
Supported Flows
- Client authorization with authorization_code
- 2-legged oauth2 authorization with JWT
Example config servlet for usage of the OAuth2 server library
OAuth2SupportServlet
class OAuth2SupportServlet extends OAuth2Servlet {
private final OAuth2Config config;
public OAuth2SupportServlet(OAuth2Config config) {
this.config = config;
}
public getConfig() {
return config;
}
}
// usage
ServletContext servletContext = servletContextEvent.getServletContext();
servletContext.addServlet("oauth2",
new OAuth2SupportServlet(OAuth2Config.newConfig()
.tokens(tokens)
.jwtKeyStore(jwtKeyStore)
.keyStore(keyStore)
.identityFinder(identityFinder)
.resourceOwnerIdentityFinder(resourceOwnerIdentityFinder)
.clientAuthorizationRepository(clientAuthorizationRepository)
.clientFinder(clientFinder)
.loginPageUrl("/ServiceLogin?continue=")
.build())
.addMapping("/o/oauth2/v1/*");
The responding interfaces are responsible for:
-
IdentityFinder - Used to find the identity of the client that is requesting authorization.
-
ClientAuthorizationRepository - Used to generate and persist auth codes for authorized clients and to use them later in the Access token request step.
-
Tokens - Used to generate Access and Refresh tokens and persist them for later use when a protected resource is requested.
-
JwtKeyStore - Used to find the Key blocks for verifying JWT authorizations
-
KeyStore - Used to find the keys used for signing and verifying of the signatures of the id_tokens.
-
ResourceOwnerIdentityFinder - Used during the authorization of the request to find the identity.
-
ClientFinder - Used to persist and find OAuth Clients
Endpoints in the OAuth2Servlet
For example if you bind your OAuth2Servlet to /o/oauth2/v1/*
-
/o/oauth2/v1/auth- Used for Authorization codes -
/o/oauth2/v1/token- Used for Access and Refresh tokens -
/o/oauth2/v1/revoke- Used to revoke Access/Refresh tokens -
/o/oauth2/v1/tokenInfoUsed to receive an id_token for the given Access token -
/o/oauth2/v1/userInfoUsed to receive a UserInfo for the given Access token -
/o/oauth2/v1/certsUsed to receive the used certificates
id_token
Our library supports the OpenID id_token (http://openid.net/specs/openid-connect-core-1_0.html) which could be obtained on the tokenInfo endpoint. Note that for optimisation purposes to lower round trips an id_token is also returned with the refresh token response and jwt token response. The id_token uses a custom header CID (Certificate ID) that can be used to recognise which certificate was used to sign the token.
ToDo
- dependency clean up
