/**
* <p>
* This class implements the Microsoft NTLM authentication protocol.
* </p>
* <p>
* NTLM is a Microsoft proprietary network authentication protocol used in many
* situations (e.g. by the Microsoft Proxy Server to authenticate a browser).
* </p>
* <p>
* It requires a JCE compatible MD4 hash algorithm implementation and
* a DES with no-padding ECB cipher to compute the requested value. <br>
* An open source JCE compatible library is Cryptix JCE and it is available
* <a href="http://www.cryptix.org/">here</a>. We are assuming that the JCE provider
* is correctly installed and configured. Notice that the Sun JCE implementation
* proviedes the DES cipher but doesn't provide the MD4 hashing.
* </p>
* To perform an authentication the following information are needed:
* <ul>
* <li>the host name (with its own domain);</li>
* <li>the user name (with its own domain);</li>
* <li>the user password.</li>
* </ul>
* Alternatively, the user password can be replaced with its Lan Manager and
* NT hashed versions. On a Windows system these data can be collected in the
* registry, otherwise they can be extracted from a SAMBA password file.<br>
* Notice that the host and user domain could not be the same.
* </p>
* <p>
* To start an NTLM authentication procedure (e.g. with a proxy server) build a
* request message calling {@link #formatRequest(String, String) formatRequest}
* and send it to the server.<br>
* Once the challenge packet has been correctly received extract from it the nonce
* with {@link #getNonce(byte[]) getNonce} function and use it to compute the
* reply and build the response message with
* {@link #formatResponse(String, String, String, byte[], byte[], byte[]) formatResponse}
* method and send it back to the server.<br>
* Repeat the previous steps until the server authenticates the client's identity
* or a large number of retries has been made. The check of a successful authentication
* is protocol specific (e.g. code 200 in HTTP), thus it is not performed by this component.
* </p>
* <p>
* We want to access to the page <code>http://www.server.com/page.html</code>
* through an NTLM proxy <code>proxy.domain.com</code> that accepts connection on
* port 80.<br>
* We access to proxy from host <code>HOSTDOMAIN\\HOST<code> with the user
* <code>USERDOMAIN\\user</code> (password <code>"1234567890"</code>).<br>
* As first step we open a socket connection to proxy server and set up the
* required object. Notice that we use a keep-alive connection, because NTLM
* authentication is connection based and the connection must be alive through the
* whole process.<br>
* <pre>
* Socket s = new Socket("proxy.domain.com", 80);
* s.setKeepAlive(true);
* InputStream is = s.getInputStream();
* OutputStream os = s.getOutputStream();
* BufferedReader r = new BufferedReader(new InputStreamReader(is));
* BufferedWriter w = new BufferedWriter(new OutputStreamWriter(os));
*
* String host = "HOST";
* String hostDomain = "HOSTDOMAIN";
* String user = "user";
* String userDomain = "USERDOMAIN";
* String password = "1234567890";
* </pre>
* Then, we format a request message and send it in a HTTP compliant GET message.<br>
* <pre>
* byte[] fstMsg = NTLM.formatRequest(host, hostDomain);
* byte[] fstMsg64 = Codecs.base64Encode(fstMsg);
* System.out.println("NTLM Request Packet: " + new String(fstMsg64));
*
* w.write("GET http://www.server.com/page.html HTTP/1.0\n");
* w.write("Host: www.server.com\n");
* w.write("Proxy-Connection: Keep-Alive\n");
* w.write("Proxy-Authorization: NTLM " + new String(fstMsg64) + "\n\n");
* w.flush();
* System.out.println("First Message Sent");
* </pre>
* We wait for the server response and we parse it to extract the nonce.<br>
* <pre>
* String resp = "";
* int contentLength = 0;
* while((line = r.readLine()) != null)
* if(line.length() == 0)
* break;
* if(line.startsWith("Content-Length"))
* contentLength = Integer.parseInt(line.substring(line.indexOf(":") + 1).trim());
* else if(line.startsWith("Proxy-Authenticate"))
* resp = line.substring(line.indexOf(":") + 1).trim();
* r.skip(contentLength);
* System.out.println("Second Message Received");
* System.out.println("Content Length: " + contentLength);
* System.out.println("Proxy-Authenticate: " + resp);
* resp = resp.substring(resp.indexOf(" ")).trim();
* System.out.println("NTLM Chellange Packet: " + resp);
* resp = Codecs.base64Decode(resp);
* byte[] sndMsg = resp.getBytes();
* byte[] nonce = NTLM.getNonce(sndMsg);
* </pre>
* With the nonce collected in the previous step we create a response message.<br>
* <pre>
* byte[] trdMsg = NTLM.formatResponse(host, user, userDomain,
* NTLM.computeLMPassword(password), NTLM.computeNTPassword(password),
* nonce);
* System.out.println(trdMsg.length);
* byte[] trdMsg64 = Codecs.base64Encode(trdMsg);
* System.out.println("NTLM Response Packet: " + new String(trdMsg64));
* </pre>
* We sent the message to the server.<br>
* <pre>
* w.write("GET http://www.server.com/page.html HTTP/1.0\n");
* w.write("Proxy-Connection: Keep-Alive\n");
* w.write("Host: www.server.com\n");
* w.write("Proxy-Authorization: NTLM " + new String(trdMsg64) + "\n\n");
* w.flush();
* System.out.println("Third Message Sent");
* </pre>
* Finally we wait the server reply.<br>
* <pre>
* System.out.println("Server response: " + r.readLine());
* </pre>
* If the reply is like <code>"HTTP/1.0 200 OK"</code> it has worked fine, else
* the server response is containing a new nonce.
* </p>
* <p>
* Notice that despite the computing of hashed passwords and of nonce response is
* exactly the same of the SMB authentication protocol, the message format is slightly
* different. <br>
* Therefore, the methods {@link #computeLMPassword(String) computeLMPassword},
* {@link #computeNTPassword(String) computeNTPassword} and
* {@link #computeNTLMResponse(byte[], byte[], byte[], byte[], byte[]) computeNTLMResponse}
* can be used to perform a SMB authentication too.
* </p>
* <p>
* This implementation is based on:
* <ul>
* <li>the reverse engineering of the NTLM protocol made by Ronald Tschalär
* and available <a href="http://www.innovation.ch/java/ntlm.html">here</a>;</li>
* <li>the documentation about NTLM provided with <a href="http://www.atstake.com/research/lc3/">
* L0phtCrack 1.5</a>;</li>
* <li>the "Handbook of Applied Cryptography", freely available
* <a href="http://www.cacr.math.uwaterloo.ca/hac/">here</a>;</li>
* <li>the C source code of NTLM library in the <a href="http://www.samba.org/">
* SAMBA Project</a>.</li>
* </ul>
* Nevertheless, because there isn't any official protocol specification publicly
* available there is any warranty that code works correctly and that it is
* conforming to Microsoft NTLM protocol.
* </p>
* <p>
* For implementation reasons only the public members perform argument consistency
* checks. The public members also catch and hide every exceptions that can be
* throwed (even though interfaces specify otherwise).
