    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkCrypt2 crypt = new CkCrypt2();

    // The BCrypt cost factor (work factor) can be set to a value from 4 to 31.
    // The default value is 10.  We'll set it here explicitly to the default value
    // to make this new property known.  This line of code can be omitted
    // if the default value of 10 is desired.
    crypt.put_BCryptWorkFactor(10);

    String bcryptHash = crypt.bCryptHash("mySecretPassword");
    System.out.println("BCrypt hash = " + bcryptHash);

    // Sample output:
    // BCrypt hash = $2a$10$H5kIVktMGzAPKGKNAe9DVu0iwEqfhv/o4MMJ/Dzw/MPy1leOE9NOK

    // Note: Your output will be different because the BCryptHash method
    // automatically generates a random salt.
