[C#]ASCIIM

This is the class.

Code:

public class ASCIIM
    {
        public byte[] Bytes;
        public byte[] Keys;
        public int KeyLength
        {
            get { return Keys.Length - 2; }
        }

        public void GetBytes(string String)
        {
            byte[] bytes = new byte[String.Length];
            bytes = Encoding.ASCII.GetBytes(String);

            for (int i = 0; i < bytes.Length; i++)
            {
                for (int u = 0; u < Keys.Length; u++)
                {
                    if (u < KeyLength)
                    {
                        int key = (int)Keys[u] ^ (int)Keys[u + 1] + ((int)Keys[u + 1] ^ (int)Keys[u]);
                        bytes[i] += (byte)key;
                    }
                    else
                        u = Keys.Length + 1;
                }
            }

            Bytes = bytes;
        }
        public string Decode()
        {
            byte[] bytes = Bytes;
            for (int i = 0; i < Bytes.Length; i++)
            {
                for (int u = 0; u < Keys.Length; u++)
                {
                    if (u < KeyLength)
                    {
                        int key = (int)Keys[u] ^ (int)Keys[u + 1] + ((int)Keys[u + 1] ^ (int)Keys[u]);
                        bytes[i] -= (byte)key;
                    }
                    else
                        u = Keys.Length + 1;
                }
            }

            return Encoding.ASCII.GetString(Bytes);
        }
        public string GetString()
        {
            string retstring = "";
            for (int i = 0; i < Bytes.Length; i++)
            {
                retstring += Bytes[i] + " ";
            }

            return retstring;
        }
    }

All it does is changing the bytes. If the keys are invalid or not entered at decoding, then you will get a wrong value back. It can be very useful. I was just playing around with it for fun and thought I would try see if it works and it did. It took maybe 5-10minutes.

Example:

Code:

ASCIIM ascii = new ASCIIM();
            ascii.Keys = new byte[]
            {
                1, 2, 1, 2, 1, 2
            };
            ascii.GetBytes("Hello World!");
            Console.WriteLine(ascii.GetString());//Writing our bytes.
Console.WriteLine(Encoding.ASCII.GetString(ascii.Bytes));//Writing decoding bytes without keys.
            Console.WriteLine(ascii.Decode());//Decoding and writing the decoded bytes.

Output:

Code:

92 121 128 128 131 52 107 131 134 128 20 53
\y???4k???x5
Hello World!

Oh and I'm unbanned :bandit:

This actually comes in handy you know? I want to make a name spoofed in my proxy, but i didn't know how to convert an string to byte[]. Thank you :)

@OELABOELA:

No offense but you could always do
for(i=0; i<strlen(myString); ++i) { myArray[i]=(BYTE)myString[i]; }

Code:

Encoding.ASCII.GetBytes(str());

Which does the same thing afaik.

Why would it be faster?

Encoding.ASCII.GetBytes();

This is marginally slower (you wouldnt even notice) than the other method, but its safer. So you should be using this method, the method in the original post is going to be much slower for seemingly little gain of anything.....

Well the one in OP is not efficient really, but I improved it and made something else from it, but that's most likely why I was about to share it. Peoples can either improve it or don't :)
