You're assuming that the result of MD5sum is the Base64 result - it
looks more like hex to me. Indeed, if you try the following program
which converts your base64 to hex, you'll see a familiar sequence...
using System;
public class Test
{
static void Main()
{
byte[] md5 = Convert.FromBase64String
("w3onGb2DunZrKdj4PO5iWA==");
Console.WriteLine (BitConverter.ToString(md5));
}
}
