/**
* 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 (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.
*
