Then I made a test project in some other folder and added cryptolib as a dependency. After that, I added the include path so I can easily include all the headers.

While files are downloading I show an animation. When does not, I hide it. The problem is that Chrome does not know when the files are fully downloaded, that is when the iframe is completely loaded. I use the iframe property readyState to check the iframe state: var iframe = document.createElement("iframe"); iframe.style.visibility = "hidden"; // I start a progress animation window.setTimeout(showProgressAnimation, 1000); // I start the file
