|
||||
* 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>
|
||||
* System.out.println("It matches");<br>
|
||||
* else<br>
|
||||
* 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 30.
