<![CDATA[Is the state of Mastodon (and most of the fediverse?) such that user/message signing keys are still all RSA?]]>Is the state of Mastodon (and most of the fediverse?) such that user/message signing keys are still all RSA? I've seen there's been some discussion of Ed25519 support, but it seems like not much progress?

But for HTTP signatures everyone still uses RSA because dominant implementations don't support Ed25519

Also, this at Github:

"Update HTTP signatures to support IETF draft from October 2021 # 21429"

What there is would seem to be here:

"Security

Public key cryptography and supported signature schemes over HTTP and JSON-LD."

That said, I can offer no support or explanation
