I guess the real question here is how to convert ed25519 to x25519 (aka curve25519). It looks like [such a thing is possible](https://libsodium.gitbook.io/doc/advanced/ed25519-curve25519). EDIT: some more on this topic: https://crypto.stackexchange.com/questions/13077/can-curve25519-keys-be-used-with-ed25519-keys

BTW, I figured out that I did not need this personally... I developed a handshake mechanism by which two users with signing keys agree on which encryption keys they would...

Never mind, I'm reopening this. I think the process of doing something along the lines of a "crypto box" as described in libsodium is still useful considering that x25519 is...

I tried writing an implementation that I think solves the issue. I'll be interested if you think it does also. It's inspired by how I *believe* libsodium's sealed boxes work:...

I appreciate the idea behind this but I have to say I'm not wild about it going into Racket *proper*. A couple of reasons: 1. JSON is currently the world's...
