The /certificates handler allows the update of SSL certificates, including reloading them, so they become active immediately.

You have to POST two files using multiple parts. The name of the parts is not relevant, nor is the order in which you sent the files.

1. The public certificate
2. The private certificate key

It is important to note that the certificates have to be valid and match each other.
