检查是否存在SSH密码

Before you generate an SSH key, you can check to see if you have any existing SSH keys.

Windows

1. Open Git Bash.

2. Enter ls -al ~/.ssh to see if existing SSH keys are present:

   $ ls -al ~/.ssh
   # Lists the files in your .ssh directory, if they exist

3. Check the directory listing to see if you already have a public SSH key. By default, the filenames of the public keys are one of the following:
   • id_rsa.pub
   • id_ecdsa.pub
   • id_ed25519.pub

If you don‘t have an existing public and private key pair, or don‘t wish to use any that are available to connect to GitHub, then generate a new SSH key.

If you see an existing public and private key pair listed (for example id_rsa.pub and id_rsa) that you would like to use to connect to GitHub, you can add your SSH key to the ssh-agent.

Tip: If you receive an error that ~/.ssh doesn't exist, don't worry! We'll create it when we generate a new SSH key.

Linux

1. Open Terminal.

2. Enter ls -al ~/.ssh to see if existing SSH keys are present:

   $ ls -al ~/.ssh
   # Lists the files in your .ssh directory, if they exist

3. Check the directory listing to see if you already have a public SSH key. By default, the filenames of the public keys are one of the following:

   • id_rsa.pub
   • id_ecdsa.pub
   • id_ed25519.pub

If you don‘t have an existing public and private key pair, or don‘t wish to use any that are available to connect to GitHub, then generate a new SSH key.

If you see an existing public and private key pair listed (for example id_rsa.pub and id_rsa) that you would like to use to connect to GitHub, you can add your SSH key to the ssh-agent.

生成新的SSH密钥

Windows

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"

   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]

Linux

1. 打开终端。

2. 粘贴以下文本，替换为您的GitHub电子邮件地址。

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

   使用提供的电子邮件作为标签，这将创建一个新的ssh密钥。

   > Generating public/private rsa key pair.

3. 当提示您“输入要在其中保存密钥的文件”时，请按Enter。这接受默认文件位置。

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

4. 在提示符下，键入一个安全密码。有关更多信息，请参阅“使用SSH密钥密码短语”。

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

将SSH密钥添加到ssh-agent

在将新的SSH密钥添加到ssh-agent来管理密钥之前，您应该已经检查了现有的SSH密钥并生成了一个新的SSH密钥。

1. 在后台启动ssh-agent。

   $ eval "$(ssh-agent -s)"
   > Agent pid 59566

2. 将SSH私钥添加到ssh-agent。如果您使用其他名称创建密钥，或者要添加具有其他名称的现有密钥，请使用私有密钥文件的名称替换命令中的id_rsa。

   $ ssh-add ~/.ssh/id_rsa

3. 将SSH密钥添加到您的GitHub帐户。

打开gitbash终端

clip <~/.ssh/id_rsa.pub

然后在Key里复制粘贴，就会有key值出现

最后，在git终端下就可以copy我们的git仓库代码了

#git clone git@github.com:YourGitHub/YourProject.git
git clone git@github.com:CarryGitHub/Demo1.git
