在Java中将MD5转换为String

    String password = "123456";    MessageDigest md = MessageDigest.getInstance("MD5");    md.update(password.getBytes());    byte byteData[] = md.digest();    StringBuffer sb = new StringBuffer();    for (int i = 0; i < byteData.length; i++)        sb.append(Integer.toString((byteData[i] & 0xff) + 0x100, 16).substring(1));    System.out.println("Digest(in hex format):: " + sb.toString());
