Where is kryptkey? I don't see it on F-droid.
I do see KryptEy, which sounds like what you're talking about. What's important to mention is that it's a proof-of-concept app that hasn't been updated in two years. It may still function fine and be secure, but I wouldn't necessarily assume that, especially when we are talking about high stakes like avoiding government intrusion into chats. Has anyone ever checked or audited it?
Can you at least start letting in trans US refugees before they all get genocided? Because it's already started.
