  * BCrypt implements OpenBSD-style Blowfish password hashing using the scheme
  * described in "A Future-Adaptable Password Scheme" by Niels Provos and David

- * <p>
+ * <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>
+ * <p/>
  * Usage is really simple. To hash a password for the first time, call the
  * hashpw method with a random salt, like this:
- * <p>
+ * <p/>
  * <code>
  * String pw_hash = BCrypt.hashpw(plain_password, BCrypt.gensalt()); <br />
  * </code>
- * <p>
+ * <p/>
  * To check whether a plaintext password matches one that has been hashed
  * previously, use the checkpw method:
- * <p>
+ * <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>
+ * <p/>
  * The gensalt() method takes an optional parameter (log_rounds) that determines
  * the computational complexity of the hashing:
- * <p>
+ * <p/>
  * <code>
  * String strong_salt = BCrypt.gensalt(10)<br />
  * String stronger_salt = BCrypt.gensalt(12)<br />
  * </code>
- * <p>
+ * <p/>
  * The amount of work increases exponentially (2**log_rounds), so each increment
