Best way to distribute a PSK when all communication is compromised?
Before you see this as a “duplicate,” this question is similar, but the circumstances of mine are very different. My scenario is purely hypothetical, but could definitely apply to people in real life.
I want to distribute a non-official pre-shared key to a “friend,” but all communications are monitored by the government, and sharing this key would get flagged. The government decrypts all traffic, and has a hold on all third parties (such as encrypted email,) so these aren’t options.
I don’t have physical access to the person I want to share the key with.
We can communicate through email and SMS, as well as mobile calls, but again, all services are controlled by the government.
What would be the best way to give my “friend" the PSK remotely, without the overarching government knowing?
My only idea currently is disguising and steganography, but those have their downsides.
