Question

How to make an Encode function based on this Decode function?
I got the source code for the Decode function on the internet but I need the Encode function.

All my attempts to make it failed and the original coder isn’t available at the moment.

The (original) code:

byte Decode(byte EncodedByte)
{
    EncodedByte ^= (byte)194;
    EncodedByte = (byte)((EncodedByte << 4) | (EncodedByte >> 4));
    return EncodedByte;
}

Answer 1

byte Encode(byte EncodedByte) 
{ 
    EncodedByte = (byte)((EncodedByte << 4) | (EncodedByte >> 4)); 
    EncodedByte ^= (byte)194; 
    return EncodedByte; 
}
