title: Password encryption in Delphi
body: <p>I need to store database passwords in a config file. For obvious reasons, I want to encrypt them (preferably with AES). Does anyone know a Delphi implementation that is easy to introduce into an existing project with > 10,000 lines of historically grown (URGH!) source code?</p>
  
  <p>Clarification: Easy means adding the unit to the project, adding max. 5 lines of code where the config file is read and be done with it. Should not take more than 15 minutes.</p>
  
  <p>Another clarification: The password is needed in order to create a connection to the db, not to support a user management scheme for the application. So using hashes does not help. The db engine checks if the password is valid, not the app.</p>
