+# SipHash
+
+[![Build Status](https://travis-ci.org/zackehh/siphash-java.svg?branch=master)](https://travis-ci.org/zackehh/siphash-java) [![Coverage Status](https://coveralls.io/repos/zackehh/siphash-java/badge.svg?branch=master&service=github)](https://coveralls.io/github/zackehh/siphash-java?branch=master)
+
+A Java implementation of the SipHash cryptographic hash family. Supports any variation, although defaults to the widely used SipHash-2-4. Can be used with either full input, or used as a streaming digest.
+
+This library was heavily influenced by [veorq's C implementation](https://github.com/veorq/siphash) and [Forward C&C's reference implementation](http://www.forward.com.au/pfod/SipHashJavaLibrary/) - I just decided it was time a Java implementation of SipHash made it onto Maven :).
+
+## Setup
+
+`siphash` is available on Maven central, via Sonatype OSS:
+
+```
+<dependency>
+    <groupId>com.zackehh</groupId>
+    <artifactId>siphash</artifactId>
+    <version>1.0.0</version>
+</dependency>
+```
+
+## Usage
+
+There are two ways of using SipHash (see below). Both return a `SipHashResult` which can be used to retrieve the result in various forms. All constructors can take arguments to specify the compression rounds. For further usage, please visit the [documentation](http://www.javadoc.io/doc/com.zackehh/siphash).
+
+#### Full Input Hash
+
+The first is to simple create a `SipHash` instance and use it to repeatedly hash using the same key.
+
+The internal state is immutable, so you can hash many inputs without having to recreate a new `SipHash` instance (unless you want a new key).
+
+```java
+SipHash hasher = new SipHash("0123456789ABCDEF".getBytes());
+
+SipHashResult result = hasher.hash("my-input".getBytes());
+
+System.out.println(result.get());                             // 182795880124085484 <-- this can overflow
+System.out.println(result.getHex());                          //  "2896be26d3374ec"
+System.out.println(result.getHex(true));                      // "02896be26d3374ec"
+System.out.println(result.getHex(SipHashCase.UPPER));         //  "2896BE26D3374EC"
+System.out.println(result.getHex(true, SipHashCase.UPPER));   // "02896BE26D3374EC"
+```
+
+#### Streaming Hash
+
+The second is to use the library as a streaming hash, meaning you can apply chunks of bytes to the hash as they become available.
+
+Using this method you must create a new digest every time you want to hash a different input as the internal state is mutable.
+
+```java
+SipHashDigest digest = new SipHashDigest("0123456789ABCDEF".getBytes());
+
+digest.update("chu".getBytes());
+digest.update("nked".getBytes());
+digest.update(" string".getBytes());
+
+SipHashResult result = digest.finish();
+
+System.out.println(result.get());                             // 3502906798476177428 <-- this can overflow
+System.out.println(result.getHex());                          //  "309cd32c8c793014"
+System.out.println(result.getHex(true));                      //  "309cd32c8c793014"
+System.out.println(result.getHex(SipHashCase.UPPER));         //  "309CD32C8C793014"
+System.out.println(result.getHex(true, SipHashCase.UPPER));   //  "309CD32C8C793014"
+```
+
+## Contributing
+
+If you wish to contribute (awesome!), please file an issue first! All PRs should pass `mvn clean verify` and maintain 100% test coverage.
+
+## Testing
+
+Tests are run using `mvn`. I aim to maintain 100% coverage where possible (both line and branch).
+
+Tests can be run as follows:
+
+```bash
+$ mvn clean verify
+```
