git ssh秘钥

[chenlong-io]

使用ssh-keygen命令生成 ssh 秘钥：

➜  ~ ssh-keygen

Generating public/private rsa key pair.
Enter file in which to save the key (/Users/aa/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/aa/.ssh/id_rsa.
Your public key has been saved in /Users/aa/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:vJ43VKHgqjiQVorBY4tZL6f2wXX6V8l6F/DjN8iLJ8o aa@AAdeMacBook-Pro
The key's randomart image is:
+---[RSA 3072]----+

查看刚才生成的秘钥：

➜  ~ ls ~/.ssh
id_rsa      id_rsa.pub  known_hosts

• id_rsa: 密钥文件
• is_rsa.pub: 公钥文件

一般 ssh 需要公钥，查看公钥：

➜  ~ cat ~/.ssh/id_rsa.pub

以 github 为例，进入用户-> settings -> SSH and GPG keys，新建一个 ssh key，将刚才的 ssh 公钥复制进去即可
