JS加密解密

调用方法示例：

<!DOCTYPE html>
<html>

    <head>
        <meta charset="UTF-8">
        <title></title>
    </head>

    <body>
        <p id="a"></p>
        <p id="b"></p>
        <p id="c"></p>
    </body>
    <script type="text/javascript" src="js/keybase.js" ></script>
    <script>
        let a = '汪政..222RRRp767868^*%^*&%&344h哈哈';
        let b = udp.d(ud(a)); // 需要加密的内容
        let c = udp.p(up(b)); // 需要解密的内容
        window.document.getElementById('a').innerHTML = "加密前的内容是：" + a;
        window.document.getElementById('b').innerHTML = "加密后的内容是：" + b;
        window.document.getElementById('c').innerHTML = "解密后的内容是：" + c;
    </script>

</html>
