So… Anons… Here is an interesting problem.
I need to be able to drop a private key to someone who is probably behind compromised communications. Exactly why they are in this predicament is a bit of a mystery to me, but as I can't yet fly to the other side of the world and start punching people in the face…
I expect that someone is able to read all messages I send to this person and that my own account on that platform is monitored as well. We have been communicating using metaphor and other such things for some time, but things have reached a degree of spoopiness that I need to be able to be blunt and direct… If overt… Without completely tipping my hand to observers.
There may be no way around it, and I just have to bite a bullet…
There are a limited range of personal comms that have been made outside the platform in question to draw from for a pass-phrase… But those will evaporate under a dictionary attack and I will need at least part of that validation chain to erase after it has been used.
I can link to external image hosts and there seems to be minimal restriction on their web activity (but this can't be confirmed).
