Updated signature function:

function lj(a) {
    a = a.split("");
    a = mj(a, 39);
    a = a.slice(2);
    a = mj(a, 57);
    a = a.slice(2);
    a = mj(a, 23);
    a = mj(a, 35);
    a = a.slice(2);
    return a.join("")
}

function mj(a, b) {
    var c = a[0];
    a[0] = a[b % a.length];
    a[b] = c;
    return a
};
