Mac 如何生成ssh public key

生成ssh public key

1.打开终端

输入ssh -v

• 出现以下内容，表示ssh文件存在

xxx@XXdeMacBook-Pro ~ % ssh -v
usage: ssh [-46AaCfGgKkMNnqsTtVvXxYy] [-B bind_interface]
           [-b bind_address] [-c cipher_spec] [-D [bind_address:]port]
           [-E log_file] [-e escape_char] [-F configfile] [-I pkcs11]
           [-i identity_file] [-J [user@]host[:port]] [-L address]
           [-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port]
           [-Q query_option] [-R address] [-S ctl_path] [-W host:port]
           [-w local_tun[:remote_tun]] destination [command]

2. 生成ssh key

ssh-keygen

• 出现以下代码

Generating public/private rsa key pair.
Enter file in which to save the key (/Users/yinqiangqiang/.ssh/id_rsa): 
/Users/yinqiangqiang/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /Users/yinqiangqiang/.ssh/id_rsa.
Your public key has been saved in /Users/yinqiangqiang/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:8QPUtJr5g4NCKiwJXHkYQ7V27NjZmMQF9Md0N/2edKs yinqiangqiang@yinqianangdeMBP
The key's randomart image is:
+---[RSA 2048]----+
|  .+...oo+.. . o.|
|    = +.o +.. . o|
|   + + =o..o    .|
|. . o * =B.    .o|
|..  .. *S.o   ..+|
|o. o   . o .   o.|
|+.. . . o o   .  |
|..   .   . . E   |
|                 |
+----[SHA256]-----+

• ssh public key生成成功

3.打开id_rsa.pub查看key

• 终端数据命令
  open ~/.ssh
• 找到id_rsa.pub文件，打开就能查看到ssh public key内容了。

了解项目代码，开权限时候用到了，记录一下。
