[Release] Inventory Encryption/decryption

[xHimura]

I made a partial inventory class which can encrypt/decrypt the inventory, so lets see how far you can go with it !

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Inventory.lib
{
    class inventory
    {
        public string key = "19800216";

        public string GetString(byte[] ascii)
        {
            string chr = Encoding.ASCII.GetString(ascii);

            return chr;
        }

        public byte[] GetBytes(string s)
        {
            byte[] bytes = Encoding.ASCII.GetBytes(s);

            return bytes;
        }

        public string Decrypt(string input)
        {
            int keyLen = this.key.Length;

            input = input.Split('#')[1];

            int inputLen = input.Length;

            string result = "";

            for (int i = 0; i < inputLen; i++)
            {
                result += (Convert.ToInt32(GetBytes(input[i].ToString())[0]) - Convert.ToInt32(GetBytes(this.key[i % keyLen].ToString())[0])) + "|";
            }

            string[] split = result.Split(Convert.ToChar("|"));

            result = "";

            byte[] temp = new byte[split.Length - 1];

            for (int i = 0; i < split.Length - 1; i++)
            {
                temp[i] = (Convert.ToByte(split[i]));
            }
            return GetString(temp);
        }


        public string Encrypt(string input)
        {
            int keyLen = this.key.Length;

            int inputLen = input.Length;

            string result = "";

            for (int i = 0; i < inputLen; i++)
            {
                result += (Convert.ToInt32(GetBytes(input[i].ToString())[0]) + Convert.ToInt32(GetBytes(this.key[i % keyLen].ToString())[0])) + "|";
            }

            string[] split = result.Split(Convert.ToChar("|"));

            result = "";

            byte[] temp = new byte[split.Length - 1];

            for (int i = 0; i < split.Length - 1; i++)
            {
                temp[i] = (Convert.ToByte(split[i]));
            }
            return GetString(temp);
        }
    }
}

And now lets see how long it takes you to figure out how to calculate the checksum of the inventory ;-)
