Jersey-based HMAC authentication for the client and server.

This library makes it easy to add HMAC authentication to REST API's that are implemented using the Jersey library. Note that this also works for Jersey-based frameworks, like Dropwizard.

HMAC authentication provides a way for you to ensure the integrity and authenticity of API requests. You grant API access to permitted callers by giving each one an API key and a secret key that they use when generating requests. You can use this library to add support for HMAC authentication on the client and server.

Getting Started

Server Side (Jersey 2.x / org.glassfish.jersey packages)

If your application uses Jersey 2.x, add this Maven dependency:

<dependency>
    <groupId>com.bazaarvoice.auth</groupId>
    <artifactId>jersey-hmac-auth-server2</artifactId>
    <version>${version}</version>
</dependency>

Modify your Jersey resource methods to include a principal annotated with @HmacAuth. For example:

@Path("/pizza")
@Produces(MediaType.TEXT_PLAIN)
public class PizzaResource {
    @GET
    public String get(@HmacAuth Principal principal) {
        // This gets control only if the request is authenticated. 
        // The principal identifies the API caller (and can be of any type you want).
    }
}

Implement an authenticator to authenticate requests:

public class MyAuthenticator extends AbstractCachingAuthenticator<Principal> {
    // some code is intentionally missing 
    
    @Override
    protected Principal loadPrincipal(Credentials credentials) {
        // return the principal identified by the credentials from the API request
    } 

    @Override
    protected String getSecretKeyFromPrincipal(Principal principal) {
        // return the secret key for the given principal
    }
}

Register the authenticator with Jersey.

public class PizzaApplication<P> extends ResourceConfig {
    public PizzaApplication() {
        // register the Feature that will tell Jersey to process the @HmacAuth annotations
        // specify your principal type here
        register(new HmacAuthFeature<String>());

        // tell Jersey about your custom Authenticator
        register(new AbstractBinder() {
            protected void configure() {
                // The P parameter is to trick HK2 into injecting the Authenticator where it is needed.
                bind(PizzaAuthenticator.class).to(new TypeLiteral<Authenticator<P>>() {});
            }
        });

        // register your resources
        register(PizzaResource2.class);
    }
}

See the jersey-hmac-auth-sample2 project for a complete working example.

Server Side (Jersey 1.x / com.sun.jersey packages)

Add this maven dependency:

<dependency>
    <groupId>com.macasaet.auth</groupId>
    <artifactId>jersey-hmac-auth-server</artifactId>
    <version>${version}</version>
</dependency>

Modify your Jersey resource methods to include a principal annotated with @HmacAuth. For example:

@Path("/pizza")
@Produces(MediaType.TEXT_PLAIN)
public class PizzaResource {
    @GET
    public String get(@HmacAuth Principal principal) {
        // This gets control only if the request is authenticated. 
        // The principal identifies the API caller (and can be of any type you want).
    }
}

Implement an authenticator to authenticate requests:

public class MyAuthenticator extends AbstractCachingAuthenticator<Principal> {
    // some code is intentionally missing 
    
    @Override
    protected Principal loadPrincipal(Credentials credentials) {
        // return the principal identified by the credentials from the API request
    } 

    @Override
    protected String getSecretKeyFromPrincipal(Principal principal) {
        // return the secret key for the given principal
    }
}

Register the authenticator with Jersey. For example, using Dropwizard:

environment.addProvider(new HmacAuthProvider(new DefaultRequestHandler(new MyAuthenticator())));

Client Side (Jersey 1.x only)

On the client side, e.g. in an SDK library that interfaces with the API, the client must build requests following the authentication contract that jersey-hmac-auth implements. You can do this in any language. However, the jersey-hmac-auth library provides support in Java for client libraries that use the Jersey Client for making HTTP requests.

Add this maven dependency:

<dependency>
    <groupId>com.macasaet.auth</groupId>
    <artifactId>jersey-hmac-auth-client</artifactId>
    <version>${version}</version>
</dependency>

Add this filter to your Jersey client (assuming you have already have a Jersey client instance):

client.addFilter(new HmacClientFilter(yourApiKey, yourSecretKey, client.getMessageBodyWorkers()));
