Git创建一个SSH KEY

一、Generating a new SSH key

1. Open Git Bash.

2. Paste the text below, substituting in your GitHub email address.

ssh-keygen -t rsa -b 4096 -C "your_email@example.com" 

// 输入这句话，连按三个回车，直接跳过下面的步骤

This creates a new ssh key, using the provided email as a label.

Generating public/private rsa key pair.

3. When you're prompted to "Enter a file in which to save the key," press Enter. This accepts the default file location.

Enter a file in which to save the key (/c/Users/you/.ssh/id_rsa):[Press enter]

4. At the prompt, type a secure passphrase. For more information, see "Working with SSH key passphrases".

Enter passphrase (empty for no passphrase): [Type a passphrase]
Enter same passphrase again: [Type passphrase again]

二、安装完成之后，输入命令 ll ~/.ssh 查看是否安装成功，出现 id_rsa（锁） 和 id_rsa.pub（钥匙） 成功

三、出现锁🔒之后，我们输入命令cat ~/.ssh/id_rsa.pub查看内容并上传github

四、创建完成之后我们可以测试一下

如果之前已经存在，输入命令rm ~./ssh/known_hosts删除之前的连接

输入命令测试连接

ssh -T git@github.com

输入yes
