Is this file secure?
Yes, absolutely. It’s completely harmless. It’s just a script to do AES encryption in the browser.
Why on every site?
Why this file is necessary?
The security system relies on AES encryption in the client browser to work. I don’t know how it works exactly, but the file is necessary.
infinityfree.net is not hosted on a free hosting account. The site gets way too much traffic for that.
Any way to remove it?
No. Doing so would make your website inaccessible.
Is it related to ?i=1
The only problem I ever had while obtaining SSL is this file!
More or less. The security system prevents all automated access to websites, including Let’s Encrypt HTTP challenges. The aes.js file is more of a symptom than a cause.
Is it possible to remove it?
Google Cloud Platform, mostly.
