Switch to ed25519 as default key type #48
Description
Activity
This has been released in v1.400.
Some top open source contributors or cryptography experts use (
ecdsa-sha2-nistp256) instead:- Filippo Valsorda (@FiloSottile): public keys, history
- Russ Cox (@rsc): public keys, history
- Jon Geater (@JAG-UK): public keys
Relevant papers:
I use
ecdsa-sha2-nistp256because it's what's supported by my YubiKey which I use throughyubikey-agent.If I used a local key it would probably be an
ed25519, although the difference is not likely to ever matter.I have p256 for very similar reasons to @FiloSottile - in other contexts (esp. web3 type engagements) I've been happily using 25519 for years. No issues with this change.
ed25519is the algorithm that GitHub recommends: https://docs.github.com/en/authentication/connecting-to-github-with-ssh/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent
