+ * 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. + * + * @author Damien Miller + * @version 0.2 + */ +public class BCrypt { + // BCrypt parameters + private static final int
