macOS 13 Ventura's Git SSH Permission denied(public key)

Host *
HostkeyAlgorithms +ssh-rsa
PubkeyAcceptedAlgorithms +ssh-rsa

If for some reason you must use RSA/SHA1 (for example, the server only accepts RSA/SHA1, and you can't change it), add this snippet to the top of the ~/.ssh/config(我的文件路径是 /private/etc/ssh/ssh_config).

It enables RSA/SHA1 in the host key and public key, which should fix this and the related "no matching host key type found" issue.
