console.log(permut(rns())); will generate your key and output to console

kran.js

function convert(integer) {
    var str = Number(integer).toString(16);
    return str.length == 1 ? "0" + str : str;
};
function rnd(max, min){
    const mini=min?min:0;
    return Math.round((Math.random()+mini)*max);
}
function rns(){
    var perm = [];
    for(let y=0;y<4;y++){
        var arr = [];
        for(let x = 0; x<2; x++){
            arr.push(convert(rnd(0xff, 0x00)));
        }
        perm.push([arr]);
    }
    return perm;
}

function permut(r){
    var s = "";
    for(let x of r){
        s+=x.join("") + "-";
    }
    s=s.split(",").join("");
    return s.substring(0, s.length - 1);;
