java-http-signature is a community maintained set of utilities for making HTTP Signature requests against the Joyent Public Cloud.
This project is a fork of the code that once existed as part of the Java Manta SDK. Currently, this project interacts directly with Bouncy Castle to create HTTP Signatures. In the future, we may use a project like httpsig-java or http-signatures-java to do the signing.
Add the latest dependency to your Maven pom.xml.
For Apache HTTP Client AuthScheme support:
<dependency>
<groupId>com.joyent.http-signature</groupId>
<artifactId>apache-http-client-signature</artifactId>
<version>LATEST</version>
</dependency>For Google HTTP Client support:
<dependency>
<groupId>com.joyent.http-signature</groupId>
<artifactId>google-http-client-signature</artifactId>
<version>LATEST</version>
</dependency>For JAX-RS Client support:
<dependency>
<groupId>com.joyent.http-signature</groupId>
<artifactId>jaxrs-client-signature</artifactId>
<version>LATEST</version>
</dependency>If you prefer to build from source, you'll also need Maven, and then invoke:
# mvn packageThe Java Cryptographic Extensions Signature class is not thread safe,
but it is entirely likely that you will want to use multiple threads
to generate HTTP signatures. You can solve this problem by using the
included ThreadLocalSigner class. However, this class has the limitation
of storing one Signer class per invoking thread. Be very careful that
you properly shut down your threads and do not accidentally create a
memory leak. To nuke all of the thread references, you can call the
clearAll() method on ThreadLocalSigner.
The ThreadLocal approach is used by default in the jaxrs-client,
the google-http-client and the apache-http-client modules.
You will need to create a HttpSigner object and then use that object as part of an Interceptor to sign the request object. For example:
public static HttpRequestFactory buildRequestFactory() {
String keyPath = "/path/to/my/rsa/key";
String login = "account_name";
String fingerprint = "b2:b2:b2:b2:b2:b2:b2:b2:f7:f7:f7:f7:f7:f7:f7:f7";
HttpSignerUtils.getKeyPair(new File(keyPath).toPath());
HttpSigner signer = new HttpSigner(keyPair, login, fingerprint);
HttpExecuteInterceptor signingInterceptor = new HttpExecuteInterceptor() {
@Override
public void intercept(final HttpRequest request) throws IOException {
httpSigner.signRequest(request);
}
};
HttpRequestInitializer initializer = new HttpRequestInitializer() {
@Override
public void initialize(final HttpRequest request) throws IOException {
request.setInterceptor(signingInterceptor);
request.setParser(new JsonObjectParser(JSON_FACTORY));
}
};
HttpTransport transport = new NetHttpTransport();
return transport.createRequestFactory(initializer);
}To use the JAX-RS Client integration, instantiate a SignedRequestClientRequestFilter with
the proper credentials, then register this instance with the JAX-RS Client.
For example:
String keyPath = "/path/to/my/rsa/key";
String login = "account_name";
String fingerprint = "b2:b2:b2:b2:b2:b2:b2:b2:f7:f7:f7:f7:f7:f7:f7:f7";
final SignedRequestClientRequestFilter signedRequestClientRequestFilter = new SignedRequestClientRequestFilter(
login,
fingerprint,
keyPath
);
Response response = ClientBuilder.newClient()
.register(signedRequestClientRequestFilter)
.target(endpointBaseUrl.toURI())
.request(MediaType.APPLICATION_JSON_TYPE)
.get();Contributions welcome! Please read the CONTRIBUTING.md document for details on getting started.
