+	 * BCrypt implements OpenBSD-style Blowfish password hashing using

+	 * Niels Provos and David Mazieres.
+	 * <p>
+	 * This password hashing system tries to thwart off-line password
+	 * cracking using a computationally-intensive hashing algorithm,
+	 * based on Bruce Schneier's Blowfish cipher. The work factor of
+	 * the algorithm is parameterised, so it can be increased as
+	 * computers get faster.
+	 * <p>
+	 * Usage is really simple. To hash a password for the first time,
+	 * call the hashpw method with a random salt, like this:
+	 * <p>
+	 * <code>
+	 * String pw_hash = BCrypt.hashpw(plain_password, BCrypt.gensalt()); <br />
+	 * </code>
+	 * <p>
+	 * To check whether a plaintext password matches one that has been
+	 * hashed previously, use the checkpw method:
+	 * <p>
+	 * <code>
+	 * if (BCrypt.checkpw(candidate_password, stored_hash))<br />
+	 * &nbsp;&nbsp;&nbsp;&nbsp;System.out.println("It matches");<br />
+	 * else<br />
+	 * &nbsp;&nbsp;&nbsp;&nbsp;System.out.println("It does not match");<br />
+	 * </code>
+	 * <p>
+	 * The gensalt() method takes an optional parameter (log_rounds)
+	 * that determines the computational complexity of the hashing:
+	 * <p>
+	 * <code>
+	 * String strong_salt = BCrypt.gensalt(10)<br />
+	 * String stronger_salt = BCrypt.gensalt(12)<br />
+	 * </code>
+	 * <p>
+	 * The amount of work increases exponentially (2**log_rounds), so 
+	 * each increment is twice as much work. The default log_rounds is
+	 * 10, and the valid range is 4 to 31.
