` public static void main(String[] args) {

    var str = "/somefolder/protected.html/KgKLp/1715158623";

    MD5 md5 = MD5.create();
    var digest = md5.digestHex(str);

    var url = "/somefolder/protected.html/" + digest + "/1715158623";

    System.out.printf(url); ///somefolder/protected.html/ffa42944fd9de29db2e4458d509873d2/1715158623

}`
