將字符串轉換成md5加密

package com.md5;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

public class StringMD5 {
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		try {
			MessageDigest md = MessageDigest.getInstance("MD5");
			String str = "123456";
			String result = MD5(str,md);
			System.out.println("result-->"+result);
		} catch (NoSuchAlgorithmException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
	public static String MD5(String strSrc,MessageDigest  md) {
		byte[] bt = strSrc.getBytes();
		md.update(bt);
		String strDes = bytes2Hex(md.digest()); // to HexString
		return strDes;
	}
	private static String bytes2Hex(byte[] bts) {
		StringBuffer des = new StringBuffer();
		String tmp = null;
		for (int i = 0; i < bts.length; i++) {
			tmp = (Integer.toHexString(bts[i] & 0xFF));
			if (tmp.length() == 1) {
				des.append("0");
			}
			des.append(tmp);
		}
		return des.toString();
	}
}

【結果】
