| <h1>Hadoop Auth, Java HTTP SPNEGO</h1> |
| <p>Hadoop Auth is a Java library consisting of a client and a server components to enable Kerberos SPNEGO authentication for HTTP.</p> |
| <p>Hadoop Auth also supports additional authentication mechanisms on the client and the server side via 2 simple interfaces.</p> |
| <p>Additionally, it provides a partially implemented derivative of the Kerberos SPNEGO authentication to allow a “mixed” form of authentication where Kerberos SPNEGO is used by non-browsers while an alternate form of authentication (to be implemented by the user) is used for browsers.</p> |

| <h2><a name="License"></a>License</h2> |
| <p>Hadoop Auth is distributed under <a class="externalLink" href="http://www.apache.org/licenses/">Apache License 2.0</a>.</p></div> |
| <div class="section"> |
| <h2><a name="How_Does_Auth_Works.3F"></a>How Does Auth Works?</h2> |
| <p>Hadoop Auth enforces authentication on protected resources, once authentiation has been established it sets a signed HTTP Cookie that contains an authentication token with the user name, user principal, authentication type and expiration time.</p> |
| <p>Subsequent HTTP client requests presenting the signed HTTP Cookie have access to the protected resources until the HTTP Cookie expires.</p> |
| <p>The secret used to sign the HTTP Cookie has multiple implementations that provide different behaviors, including a hardcoded secret string, a rolling randomly generated secret, and a rolling randomly generated secret synchronized between multiple servers using ZooKeeper.</p></div> |
