Delphi 的编码与解码(或叫加密与解密)函数

uses EncdDecd;

const str = '万一的 Delphi 博客';

procedure TForm1.Button1Click(Sender: TObject);
var
strEncode,strDecode: string;
begin
strEncode := EncodeString(str);
strDecode := DecodeString(strEncode);
ShowMessageFmt('%s'#10#13'%s', [strEncode, strDecode]);
end;

procedure TForm1.Button2Click(Sender: TObject);
var
strEncode,strDecode: string;
begin
strEncode := EncodeBase64(BytesOf(str), Length(BytesOf(str)));
strDecode := StringOf(DecodeBase64(strEncode));
ShowMessageFmt('%s'#10#13'%s', [strEncode, strDecode]);
end;
