I’m using Signal, but after I found out that it’s not as privacy-friendly as it claims, I’m uneasy about sharing my address there. I trust the person who asked for my address, but not the service. What’s a safe way to share? I was thinking of something like a self-destructing pastebin, but surely you have better ideas.
I guess you can use wormhole to transport the data to your peer, and if you’re extra paranoid encrypt it asymmetrically with something like age.
Then again you can just encrypt it with age and send it over Signal. There should be no risk involved in sharing public keys even if you don’t trust their servers.
