BCrypt Hash a Password

See more Encryption Examples

Example to BCrypt hash a password.

Note: This example requires Chilkat v9.5.0.65 or greater.

Pascal (Lazarus/Delphi)

program ChilkatDemo;

// Demonstrates using the Chilkat Pascal wrapper via the C bridge DLL.
// Builds as a console application under Lazarus (FPC) or Delphi.

{$ENDIF}
{$APPTYPE CONSOLE}

  Chilkat.Crypt2;

procedure RunDemo;
var
  crypt: TCrypt2;
  bcryptHash: string;

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

  crypt := TCrypt2.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.
  crypt.BCryptWorkFactor := 10;

  bcryptHash := crypt.BCryptHash('mySecretPassword');
  WriteLn('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.
