------解决方案--------------------
搜索 70-66-A4-0F-42-77-69-CC-43-34-7A-A9-6B-72-93-1A
可知这个是 123456 的 MD5，而不是 111111 的 MD5
有人说转成 unicode 编码再 MD5 就可以得到
但遗憾的是 无论是转成 ucs-2be、ucs-2le、ucs-4le、ucs-4be 在php 中都不能 MD5 成

------解决方案--------------------

能凑活用：
PHP code

$str = md5("111111");
echo $str . "
";
#96e79218965eb72c92a549dd5a330112

function encode($str) {
    $newstr = null;
    for ($i = 0; $i < strlen($str); $i++) {
        $new = substr($str, $i, 1);
        if ($i == strlen($str) - 1) {
            $newstr .= (++ $new);
            break;
        }
        if ($new == 9)
            $newstr .= "*-";
        else
            $newstr .= (++ $new) . "-";

    }
    return $newstr;
}
echo encode($str) . "
";
#*-7-f-8-*-3-2-9-*-7-6-f-c-8-3-d-*-3-b-6-5-*-e-e-6-b-4-4-1-2-2-3

function decode($str) {
    $new="";
    $arrStr = explode("-", $str);
    foreach ($arrStr as $k => $value) {
        $val = ord($value);
        $tmp = chr(--$val);
        if($tmp === ")")
            $tmp = 9;
        $new.=$tmp;
    }
    return $new;
}
echo decode(encode($str))."
";
