There are no readymade tools for this. You could try throwing it at chatgpt and see if it works, but its very likely to make mistakes. best bet is to do it by hand

amm the function is this one 
g = Math.round(1E11 * Math.random()) + "";
f = function() {
    for (var v = [], w = 0; 64 > w;)
        v[w] = 0 | 4294967296 * Math.sin(++w % Math.PI);
    return function(y) {
        var z, D, E, H = [z = 1732584193, D = 4023233417, ~z, ~D]
            , F = []
            , x = unescape(encodeURI(y)) + "\u0080"
            , u = x.length;
        y = --u / 4 + 2 | 15;
        for (F[--y] = 8 * u; ~u;)
            F[u >> 2] |= x.charCodeAt(u) << 8 * u--;

nope

also I can already tell its not the same unescape(encodeURI(y)) + "\u0080" does not "translate" into Encoding.UTF8.GetString(Encoding.UTF8.GetBytes(y)) + "\u0080";

you shouldn't be creating a new instance of Random inside the method it's seeded with system time by default, so if you call it fast enough it will generate duplicates ah, news to me
