| jacanosalado 05. Jan, 00:19 | Yayyy, I nailed it, spent two nights on this one. It was hard and fun on equal terms. keygen: static void Main(string[] args) { var name = "jacanosalado"; var reverseNameInHex = string.Join(string.Empty, name.Reverse().Select(c => string.Format("{0:X2}", Convert.ToInt32(c)))); var serial = Convert.ToBase64String(ASCIIEncoding.ASCII.GetBytes(reverseNameInHex)); Console.WriteLine("name: {0}", name); Console.WriteLine("serial: {0}", serial); } name: jacanosalado serial: NkY2NDYxNkM2MTczNkY2RTYxNjM2MTZB Hope I had some time to write a nice tutorial. This crackme really deserves it :D |
