Add ability to sign & verify EdDSA signatures

We're using node-jose under the hood, which does not support EdDSA. The reason for this is that node-jose supports both a node and browser environment. EdDSA is not (yet) included in webcrypto.

We like to keep all verification of tokens logic client-side for privacy reasons, so switching to another library that supports EdDSA is currently not an option.

I'm aware of this, I just wanted to keep track of the issue.

By the way, I've already reached my goal: now it is tracked and when EdDSA will get into webcrypto, I'll reopen it 👍

When EdDSA support gets added to webcrypto we'll definitely add it here too :)

Ciao, Filippo! I am Dan from Okta. I am currently working on releasing the v2 of jwt.io :) We are working on adding support for EdDSA. At this moment, support is only provided directly via Firefox and Safari for Ed25519. Chrome appears to support it after enabling a set of flags:

There appears to be no support for the Ed448 curve. Does this match your expectations of what support would be as of now, Dec 2024? :)

[Slamdunk]

Definitely yes 🙂
