MD5加密和SHA加密

     * 
     * @param 待加密字符串
     * @return 返回32位md5码
     */
    public static String md5Encode(String inStr) throws Exception {
	MessageDigest md5 = null;
	try {
	    md5 = MessageDigest.getInstance("MD5");
	} catch (Exception e) {
	    System.out.println(e.toString());
	    e.printStackTrace();
	    return "";
	}

	byte[] byteArray = inStr.getBytes("UTF-8");
	byte[] md5Bytes = md5.digest(byteArray);
	StringBuffer hexValue = new StringBuffer();

	    int val = ((int) md5Bytes[i]) & 0xff;
	    if (val < 16) {
		hexValue.append("0");
	    }
	    hexValue.append(Integer.toHexString(val));
	}
	return hexValue.toString();
    }
