Multiple passwords in one ZIP file?

[neao2009]

I have read that article Multiple passwords in one ZIP file, but I still can not set multiple password to a compressed file, how to write.

FZip.KeepZipOpen := True;
FZip.ZipName := ExtractFilePath(ParamStr(0)) + 'Zip.gip';
FZip.RootDir := ExtractFilePath(ParamStr(0)) + 'Zip';
FZip.FilesList.Add('1.txt');
FZip.Password := '123';
FZip.Zip;
FZip.FilesList.Add('2.txt');
FZip.Password := '456';
FZip.Zip;
