Access Delphi Prism Class Library from Delphi XE

I need to access in Delphi XE the method "Auth" from this Delphi Prism class library:

    namespace ClassLibrary1;

    interface

    uses
      System,
      System.IO,
      System.Security.Cryptography,
      System.Runtime.InteropServices,
      System.Text;

    type
      ConsoleApp = public class
      private
        class method hashMe(input: string): string;
        class method Encrypt(clearText: string; Password: string; Salt: array of byte; iteration: Integer): string;
        class method Encrypt(clearData: array of byte; Key: array of byte; IV: array of byte): array of byte;
        class method Encrypt(clearData: array of byte; Password: string; Salt: array of byte; iteration: integer): array of byte;
        class method Decrypt(cipherText: string; Password: string; Salt: array of byte; iterations: Integer): string;
        class method Decrypt(cipherData: array of byte; Password: string; Salt: array of byte; iterations: integer): array of byte;
        class method Decrypt(cipherData: array of byte; Key: array of byte; IV: array of byte): array of byte;
      protected
      public
        [UnmanagedExport('Auth')]
        class method Auth(userName: String; userPassword: String): String;
      end;

    implementation
[...]

This is very easy with CrossTalk, but CrossTalk is very expensive and this code is for a pet project. Any easy way to do this?

TIA

function Auth(userName: PAnsiChar; userPassword: PAnsiChar): PAnsiChar; stdcall; external 'ClassLibrary1.dll'

But returning a PAnsiChar is not really a good idea in unmanaged/win32 code. Who is going to free the string?
