The purpose of tlsredirect.xyz is to allow people using FBI on the ds to scan qr codes from github and other https/hsts/tls sites. Currently FBI doesn't support tls1.3/hsts so github is completely broken.
How It Works
TLSRedirect works by taking in the link provided downloading the file and then reserving it simple as that.
Simply drop whatever direct download link you want into it and it will reserve it to you.
This will serve you the FBI.cia file from github just redirected through my server.
Or you can use the sites built in QR Code generator to create a scannable link to the file.
