I have a question that will require extensive work, and is unlikely to be solvable within the bounty period. I'd like to offer the maximum possible bounty for it, but I absolutely want that bounty going to someone.
Would it be an abuse of the system for me to note that I would offer a bounty, wait till I get a working answer, then posting and awarding the bounty? I'd alternatively do it without announcing it, taking into account the time/effort needed to answer the question.
I'd note there is a very clear, specific outcome I require - which is that those keys be detected at all, and that would be included. Also, if I get the outcome myself, whoever put in the most obvious effort, or was most useful in finding the effort should get the reputation (so there's no room for me to weasel out)
