Protect assets critical to challenge completion

[DaQuirm]

Make resources that challenge participants should not be able to obtain in any way other than completing the challenge configurable so that they are defined upon challenge start on the server machine (that participants have no access to) or encrypt them to prevent anyone from accessing them directly. This feature will allow to use this repo and all its information for the participants' benefit.

Whoa, that was a long write indeed 😅
