Anonymous43 are you referring to SSL (a protocol for secure HTTP connections) or SSH (a protocol for secure shell connection)?
If you are referring to a web command line client, most likely it's not the solution to the problem you are facing because if your host doesn't let you establish an SSH connection, very likely they won't offer the PHP modules are resources required to establish command line from the web either (too low execution time, or blocked exec functions).
If you really need a web command line access and the host doesn't prevent it, you could install this as a separate application. I'm sure there are plenty of packages for that. It doesn't need to be a Flarum extension.
