ed25519 #71

Closed maemigh closed 3 years ago

maemigh commented 3 years ago

Is ed25519 supported?

I noticed this module is using an older version of crypto and I wasn't able to find details of when support was added.

Not sure what you mean by "and older version of crypto". we use the standard library crypto package. The TLS config if specified here: https://github.com/QubitProducts/exporter_exporter/blob/master/main.go#L246-L254, it prefers ECDHE and ECDSA, however we set min TLS to 1.2, when negotiating 1.3, those settings are ignored and the go standard library takes care of things, then I believe an Ed25519 cert would work.

Thanks for the quick response. Unless I am misunderstanding, isn’t go.mod locking the crypto version to a 2019 version?

Ed25519 has been in the standard library for a while now: https://golang.org/pkg/crypto/ed25519/ The standard library crypto/tls uses the standard library crypto packages by default. x/crypto is being pulled in via logrus (and x/crypto/ssh/terminal , for some reason). It's not used for the web service.

Great, thanks!
