EvOlUtIoN Posted March 28, 2014 Share Posted March 28, 2014 Good idea to remove the EP and to break some of the PE in order to avoid debug Serial is easy to find and generate. Thanks Link to comment Share on other sites More sharing options...
kao Posted March 28, 2014 Share Posted March 28, 2014 (edited) Such a nice protection - and then you ruin it by calculating correct serial.. Keygen attached, relevant source code: private void button1_Click(object sender, EventArgs e){ // get username byte[] username = Encoding.ASCII.GetBytes(textBox1.Text); // calc CRC part 1 byte[] part1 = BitConverter.GetBytes(Crc32.CRC32Bytes(username)); // calc CRC part 2 Array.Resize(ref username, 4); byte[] part2 = BitConverter.GetBytes(Crc32.CRC32Bytes(username)); // show the serial string serial = ""; foreach (byte b in part1) { serial += String.Format("{0:X2}", ; } foreach (byte b in part2) { serial += String.Format("{0:X2}", ; } textBox2.Text = serial;}EDIT:removed garbage linekg_woot332.zip Edited March 28, 2014 by kao Link to comment Share on other sites More sharing options...

SmilingWolf Posted March 28, 2014 Share Posted March 28, 2014 I had fun unpacking it, a bit less keygenning it... but a KeygenMe is a KeygenMe, so here is my solution. Thanks for the challenge Keygen-STC.7z 3 Link to comment Share on other sites More sharing options...

WormFC Posted March 30, 2014 Share Posted March 30, 2014 I liked this but than I saw the generation algorithm which was simply too easy.Anyways thanks for the challenge, always appreciated.As usual nice solution guys.(Don't think there is a point in showing mine.. same thing in different language).
