md5test.java

eclipse下使用pojo方式基于axis2的webSErvice例子

package md5.test;

import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

public class Md5Test {
	 
	public static void main(String[] args) throws NoSuchAlgorithmException 
	
    {
		String data ="message digest";
		MessageDigest digest = MessageDigest.getInstance("MD5");
        System.out.println(toHexString(digest.digest(data.getBytes())));
		
    }
	
	
    private static String toHexString(byte b[])
    {
        int pos = 0;
        char[] c = new char[b.length * 2];
        for (int i = 0; i < b.length; i++) {
            c[pos++] = toHex[ (b[i] >> 4) & 0x0F];
            c[pos++] = toHex[b[i] & 0x0f];
        }
        return new String(c);
    }
    /**

    private static final char[] toHex = {
        '0', '1', '2', '3', '4', '5', '6',
        '7', '8', '9', 'a', 'b', 'c', 'd',
        'e', 'f'};
