crypt := CkCrypt2_Create();

// 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.
CkCrypt2_putBCryptWorkFactor(crypt,10);

bcryptHash := CkCrypt2__bCryptHash(crypt,'mySecretPassword');
Memo1.Lines.Add('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.
