git生成/添加SSH公钥生成/添加SSH公钥你可以按如下命令来生成 sshkey:ssh-keygen -t ed25519 -C "xxxxx@xxxxx.com" # Generating public/private ed25519 key pair...注意：这里的 xxxxx@xxxxx.com 只是生成的 sshkey 的名称，并不约束或要求具体命名为某个邮箱。现网的大部分教程均讲解的使用邮箱生成，其一开始的初衷仅仅是为了便于辨识所以使用了邮箱。按照提示完成三次回车，即可生成 ssh key。通过查看 ~/.ssh/id_ed25519.pub 文件内容，获取到你的 public keycat ~/.ssh/id_ed25519.pub # ssh-ed25519 AAAAB3NzaC1yc2EAAAADAQABAAABAQC6eNtGpNGwstc....这样就大功告成啦~
