le.com 算法很简单tkey，网站里搞的挺复杂，精简出来就这么点

    time = new Date().valueOf() /1e3;
    var Key = {
        getMmsKey: function(e) {
            var t = 185025305
              , r = 8
              , n = e;
            n = this['rotateRight'](n, r);
            var o = n ^ t;
            return o
        },
        rotateRight: function(e, t) {
            for (var r, n = 0; t > n; n++)
                r = 1 & e,
                e >>= 1,
                r <<= 31,
                e += r;
            return e
        },

    };
    console.log(Key.getMmsKey(time));

php算法

function getMmsKey($e) {
    $t = 185025305;
    $r = 8;
    $n = $e;
    $n = rotateRight($n, $r);
    $o = $n^$t;
    return $o;
}
function rotateRight($e, $t) {
    for ($r, $n = 0; $t>$n; $n++) {
        $r = 1 & $e;
        $e >>= 1;
        $r <<= 31;
        $e += $r;
    }
    return $e;
