[.NET]KeyGenMe/UnpackMe

Rate this question

Question

cawk

Difficulty : 4/10
Language : .NET
Platform : windows
OS Version : tested on win 10
Packer / Protector : 2 public protectors and a smaller protector coded by me to help stop public tools working 100% 

Description :

Little keygenme or unpackme I put together uses 2 public protectors but on one of them I added my own method to it to stop public tools working 100% meaning you might need to do some manual work 

Aims:

1) Get a valid key 
2) Unpack it fully
3) Make a keygen

Keygen:

Spoiler

        private static void Main(string[] args)
        {
            string name = RandomString(14);
            StringBuilder nameStr = new StringBuilder(name)
            {
                [3] = 'R',
                [13] = '$'
            };

            string key = RandomString(14);
            StringBuilder keyStr = new StringBuilder(key)
            {
                [3] = 'a',
                [5] = 'c',
                [11] = '2'
            };

            Console.WriteLine(nameStr);
            Console.WriteLine(keyStr);
            Console.Read();
        }

        private static string RandomString(int length)
        {
            const string chars = "ABCDEFGHJKLMNPQRSTUVWXYZ0123456789";
            return new string(Enumerable.Repeat(chars, length)
                .Select(s => s[Random.Next(s.Length)]).ToArray());
        }
