Hex Encode/Decode String In C#

The same code is posted all over the news groups and Internet, but here it is, easy as a snippet for myself and for you to use.

I don’t even get credit for this as what I have pretty much matches up to what other people have already posted.

This is much easier in Python.

Encode a byte array

public static string HexEncode(byte[] data)
    return BitConverter.ToString(data).Replace("-", string.Empty);

Decode a hex necoded string

public static byte[] HexDecode(string hexEncoded)
    int numChars = hexEncoded.Length;
    byte[] retVal = new byte[numChars / 2];
    for (int i = 0; i < numChars; i += 2)
        retVal[i / 2] = Convert.ToByte(hexEncoded.Substring(i, 2), 16);
    return retVal;
