Gistもあるな

https://github.blog/2023-03-23-we-updated-our-rsa-ssh-host-key/ に従うけどgistも一緒に

$ ssh-keygen -R github.com
$ ssh-keygen -R gist.github.com
$ curl -sL https:// api.github.com/meta | jq -r '.ssh_keys | .[]' | sed -e 's/^/github.com /' >> ~/.ssh/known_hosts
$ curl -sL https:// api.github.com/meta | jq -r '.ssh_keys | .[]' | sed -e 's/^/gist.github.com /' >> ~/.ssh/known_hosts

3種類の公開鍵をもらえたっぽい

$ curl -sL https:// api.github.com/meta | jq -r '.ssh_keys | .[]' | cut -f1 -d\

The GitHub Blog · We updated our RSA SSH host keyAt approximately 05:00 UTC on March 24, out of an abundance of caution, we replaced our RSA SSH host key used to secure Git operations for GitHub.com.

known_hostsの公開鍵の指紋は下記で確認できるっぽい

$ grep 'github.com ssh-rsa' .ssh/known_hosts | ssh-keygen -l -f -
