Upgrade openssl encryption to a more secure algorithm

For the original poster (OP) to fill in:

Introduction

The title of the blueprint and a short description of what the feature is.
OpenSSL has deemed RC4 as an insecure algorithm for encryption, it would be nice to have players/servers upgraded to a more secure algorithm like AES256-GCM

User Story

The user story that generated this feature request

Players connect to the CMS and authenticate via https using whatever protocol your webserver has configured. For Cloud that’s TLS 1.2/1.3

RC4 is used to authenticate command messages sent over XMR. These command messages don’t include secrets.

We are looking at replacements for XMR, likely based around websockets, but don’t have anything to announce in that regard currently
