A client at the last minute has asked if the site I have developed for them can be hosted on https instead of the current http. I have never used https for a site so have no idea what is involved or what the implications are.

The site in question is hosted on a shared hosting linux server. The site is essentially just a one page site for uploading video files coded in PHP and using a MYSQL database to store data associated with the video files uploaded.

So 2 questions really.

Is it simply a case of asking the hosting company to transfer the site from http to https

Will changing from http to https require any recoding of the site.

Sorry if dumb questions but I really have no idea.
