POUTF-16 Encoding in Java versus C#

Body
copied!<p>I am trying to read a String in UTF-16 encoding scheme and perform MD5 hashing on it. But strangely, Java and C# are returning different results when I try to do it. </p> <p>The following is the piece of code in <strong>Java</strong>:</p> <pre><code>public static void main(String[] args) { String str = "preparar mantecado con coca cola"; try { MessageDigest digest = MessageDigest.getInstance("MD5"); digest.update(str.getBytes("UTF-16")); byte[] hash = digest.digest(); String output = ""; for(byte b: hash){ output += Integer.toString( ( b & 0xff ) + 0x100, 16).substring( 1 ); } System.out.println(output); } catch (Exception e) { } } </code></pre> <p>The output for this is: <strong>249ece65145dca34ed310445758e5504</strong></p> <p>The following is the piece of code in <strong>C#</strong>:</p> <pre><code> public static string GetMD5Hash() { string input = "preparar mantecado con coca cola"; System.Security.Cryptography.MD5CryptoServiceProvider x = new System.Security.Cryptography.MD5CryptoServiceProvider(); byte[] bs = System.Text.Encoding.Unicode.GetBytes(input); bs = x.ComputeHash(bs); System.Text.StringBuilder s = new System.Text.StringBuilder(); foreach (byte b in bs) { s.Append(b.ToString("x2").ToLower()); } string output= s.ToString(); Console.WriteLine(output); } </code></pre> <p>The output for this is: <strong>c04d0f518ba2555977fa1ed7f93ae2b3</strong></p> <p>I am not sure, why the outputs are not the same. How do we change the above piece of code, so that both of them return the same output?</p>
