Java MD5 Performance Test

gistfile1.java

import java.io.UnsupportedEncodingException;
import java.security.*;

public class md5 {

	public static void main(String[] args) throws UnsupportedEncodingException, NoSuchAlgorithmException{

		for(int a = 0; a < 10; a++){

			long creationDate = System.currentTimeMillis();


			for(int i = 0; i< 100000; i++){


				byte[] bytesOfMessage = ("This is Dart!" + i).getBytes("UTF-8");

				MessageDigest md = MessageDigest.getInstance("MD5");
				byte[] thedigest = md.digest(bytesOfMessage);
				StringBuffer sb = new StringBuffer();
                                // can be removed
		                for (int ii = 0; ii< thedigest.length; ++ii) {
		                   sb.append(Integer.toHexString((thedigest[ii] & 0xFF) | 0x100).substring(1,3));
		                }
				//System.out.println(sb.toString());
			}

			System.out.println(System.currentTimeMillis() - creationDate);
			
		}
	}
}

This happened to pop up through Google, so just a small warning: this spends more time in toHexString than in digest.
