创建公私钥对连接远程仓库

参考

https://gitee.com/help/articles/4181#article-header0

步骤

ssh-keygen -t rsa -C "[e-mail]" 在本地生成 rsa 公私钥。直接回车。名称必须是默认的id_rsa。

将公钥保存到码云

ssh -T [e-mail] 测试连接生成 known_hosts 文件，测试连接的时候要输入 yes 不能直接回车

ssh-keygen生成公私钥

1@DESKTOP-3H9092J MINGW64 /e/mozq/00store/01
$ ssh-keygen -t rsa -C "[e-mail]"
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/1/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/1/.ssh/id_rsa.
Your public key has been saved in /c/Users/1/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:3n4Ctfa9e59mAKmFxxY+4z+3i7Y73vrB46iAO9wL5q0 [e-mail]
The key's randomart image is:
+---[RSA 3072]----+
|                 |
|           .     |
|          + o    |
|         ..@     |
|        S.*.+    |
|       .ooo. ..  |
|      .+o+.....+ |
|      oo+oo o=*+=|
|       Eooo++B&@=|
+----[SHA256]-----+

测试连接生成know_hosts文件

1@DESKTOP-3H9092J MINGW64 /e/mozq/00store/01
$ ssh -T [e-mail]

Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

注意

私钥名称必须为默认的id_rsa，并且放在用户目录的.ssh文件夹下。

C:Users1.ssh>tree /f
卷 Windows 的文件夹 PATH 列表
卷序列号为 AE9A-3125
C:.
│  id_rsa
│  id_rsa.pub
│  known_hosts

同时连接多个库，这些库默认都是读取id_rsa文件，可以建立文件夹，用哪个库把哪个库的rsa文件粘贴出来。比如我要用学成的公私钥，我就把他粘贴出来放到 .ssh文件夹中。

C:Users1.ssh>tree /f
卷 Windows 的文件夹 PATH 列表
卷序列号为 AE9A-3125
C:.
│  id_rsa
│  id_rsa.pub
│  known_hosts
│
├─sand
│      id_rsa
│      id_rsa.pub
│      known_hosts
│
├─store_sand
│      id_rsa
│      id_rsa.pub
│      known_hosts
│
└─xc
        id_rsa
        id_rsa.pub
        known_hosts
