+/**
+ * BCrypt implements OpenBSD-style Blowfish password hashing using
+ * the scheme described in "A Future-Adaptable Password Scheme" by
+ * Niels Provos and David Mazieres.
+ *
+ * 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.
+ *
+ * Usage is really simple. To hash a password for the first time,
+ * call the hashpw method with a random salt, like this:
+ *
+ *
+ * String pw_hash = BCrypt.hashpw(plain_password, BCrypt.gensalt());
+ *
+ *
+ * To check whether a plaintext password matches one that has been
+ * hashed previously, use the checkpw method:
+ *
+ *
+ * if (BCrypt.checkpw(candidate_password, stored_hash))
+ * System.out.println("It matches");
+ * else
+ * System.out.println("It does not match");
+ *
+ *
+ * The gensalt() method takes an optional parameter (log_rounds)
+ * that determines the computational complexity of the hashing:
+ *
+ *
+ * String strong_salt = BCrypt.gensalt(10)
+ * String stronger_salt = BCrypt.gensalt(12)
+ *
+ *
+ * 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 30.
+ *
