UTF-16 Encoding in Java versus C# -

i trying read string in utf-16 encoding scheme , perform md5 hashing on it. strangely, java , c# returning different results when try it.

the following piece of code in java:

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) {      } } 

the output is: 249ece65145dca34ed310445758e5504

the following piece of code in c#:

   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);         } 

the output is: c04d0f518ba2555977fa1ed7f93ae2b3

i not sure, why outputs not same. how change above piece of code, both of them return same output?

utf-16 != utf-16.

in java, getbytes("utf-16") returns big-endian representation optional byte-ordering mark. c#'s system.text.encoding.unicode.getbytes returns little-endian representation. can't check code here, think you'll need specify conversion precisely.

try getbytes("utf-16le") in java version.
