一个js加密

var indexess = "xno:L9y☆,$GM➨zhOR?b]⋌sX㏑✂&꒰F2a❅j(4=✎☒/q_㏕kD70㏒EAU8◄Iw3☧☩✩ઈ♆Nt➢%K;e6☓B☁lv❆P@CYuV♘|~r♗p^c.i℉g1f!QH✪S5dJ℃mWTZ[㏎-";

function jiemi(enced) {
    return enced.split('').map(
        function (ele) {
            var index = indexess.indexOf(ele);
            return index == -1 ? ele : table[index]
        }
    ).join('')
}
//反推加密函数
function jiami(enc) {
    return enc.split('').map(
        function (ele) {
            var index = table.indexOf(ele);
            return index == -1 ? ele : indexess[index]
        }
    ).join('')
}
var enced = jiami("console.log('hello');") //xC☆TCb_LbCRc'!_bbC')☁
var deced = jiemi(enced); //"console.log('hello');"
console.log(enced);
console.log(deced);
new Function(deced)(); //exec code

出来的效果倒是挺唬人的hhhc
