github 报错提示 ERROR: You're using an RSA key with SHA-1，RSA不能用，需要升级

ERROR: You're using an RSA key with SHA-1, which is no longer allowed. Please use a newer client or a different key type.
Please see https://github.blog/2021-09-01-improving-git-protocol-security-github/ for more information.

解决办法：

# 生成新秘钥，如果报错 unknown key type ed25519，使用这个：ssh-keygen -t ecdsa -b 521 -C "your_email@example"，一路回车（第一个回车是生成秘钥的名字，不给就默认，后两个是密码，可以不要）
$ ssh-keygen -t ed25519 -C "your_email@example"

# 启动 ssh 代理，根据环境，使用不同的命令
$ eval "$(ssh-agent -s)"

# 将秘钥添加到代理中，如果还有其他以前秘钥，也要添加进去
$ ssh-add id_ed25519

# 查看秘钥，并复制粘贴到GitHub
$ cat ~/.ssh/id_ed25519.pub

# 测试，最好是拉取一个项目看看，可不可以访问
$ ssh -T git@github
