Many people use JWS "JWT" to replace server side session management. They don't use JWE's and they'll only ever use one signing algorithm at a time. If you're one of these people (you probably are), you are the target audience for this repo.
Although this isn't endorsed by @FiloSottile (Filippo Valsorda), it's influenced by his twitter thread of valid JWS complaints: https://twitter.com/FiloSottile/status/1288964453065797632
This repo contains a simple Ed25519 wrapper module for golang that you could use to replace JWT signing.
