+/**
+ * BCrypt implements OpenBSD-style Blowfish password hashing using the scheme described in "A Future-Adaptable Password
+ * Scheme" by 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 (logRounds) 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**logRounds), so each increment is twice as much work. The default
+ * logRounds is 10, and the valid range is 4 to 31.
+ *
+ * @version 0.2
