public static String fromBytesToHex(byte[] result){    StringBuilder builder =new StringBuilder();    for (inti = 0;i < result.length;i++) {        if(Integer.toHexString(0xFF &result[i]).length()==1){            builder.append("0").append(Integer.toHexString(0xFF &result[i]));        }else{            builder.append(Integer.toHexString(0xFF &result[i]));        }    }    return builder.toString();}
