在本指南中，我们将看到在 Windows 11 或 Windows 10 中生成SSH 密钥的简单方法^{(SSH key)}。SSH或Secure Shell是一种加密网络协议，可在不安全的网络上建立安全隧道，以便您的数据可以在服务器之间传输以及加密形式的客户端。

例如，假设我有一个家庭网络并且它不安全。在这种情况下，如果我必须将数据从源传输到目的地，那么网络犯罪分子可能会使用中间人 (MITM)^{(Man in the middle (MITM))}方法对其进行攻击。但是，如果我使用SSH协议来执行相同的任务，那么使用加密技术的通信将保持安全。

^(Generate)在Windows 11/10生成SSH密钥

为了在Windows 11/10SSH密钥，您需要首先确保您已在设备上安装了 OpenSSH 客户端功能^{(installed the OpenSSH Client feature)}。Open SSH支持所有SSH协议版本并提供安全的隧道功能。它会加密您的所有流量并避免被劫持的风险。

因此，打开 Windows 设置并导航到Apps > Apps和功能。在右窗格中，单击可选功能^{(Optional features)}链接。

视窗 11

视窗 10

现在，检查OpenSSH 客户端^{(OpenSSH Client)(OpenSSH Client)}是否在列表中可用。

如果列表中不可用，请单击“添加功能”^{(Add a feature)}按钮。从列表中选择OpenSSH 客户端^{(OpenSSH Client)}，然后安装它。

正确安装后，重新启动计算机以确保。

在下一步中，打开 Command Prompt。打开后，键入以下命令行并按Enter。

ssh-keygen

这时候系统会要求你保存默认位置。您可以通过按Enter 键^(Enter)来执行此操作。您也可以根据需要更改路径。但是，默认情况下，它以以下形式提供位置：

C:\users\<yourusername>\.ssh\id_rsa

之后，系统会要求您设置密码（密码）。输入密码时，您将看不到任何内容，但会记录在那里。接下来^(Next)，输入相同的密码进行确认。

如果需要，您可以继续操作而无需设置密码。为此，只需按 Enter^(Enter)键，否则，在此处输入密码。

当您按下Enter键时，您的密钥和SHA256的指纹将出现。默认算法是 RSA 2048。

公钥将保存到id_rsa.pub文件中。默认情况下，它位于以下形式：

C:\users\<yourusername>\.ssh\id_rsa.pub

出于显而易见的原因，我们建议您不要共享私有SSH密钥(id_rsa) 。

我希望本指南有助于为您的系统生成 SSH 密钥。^{(I hope this guide would be helpful to generate SSH keys for your system.)}

How to generate an SSH key in Windows 11/10

Іn this guide, we will see an easу method to generаte an SSH key in Windows 11 or Windows 10. SSH or Secure Shell is a cryptographic network protocol that makes a secure tunnel over the unsecured network so that your data can be transferred between the server and the clients in an encrypted form.

For example, suppose I have a home network and it’s not secured. In this case, If I have to transfer data from a source to a destination, then it can be attacked by cybercriminals using the Man in the middle (MITM) approach. However, if I use the SSH protocol to perform the same task, then the communication would remain secured using cryptographic technology.

Generate an SSH key in Windows 11/10

In order to generate the SSH key in Windows 11/10, you need to first ensure that you have installed the OpenSSH Client feature on your device. OpenSSH supports all SSH protocol versions and provides secure tunneling capabilities. It encrypts all your traffic and avoids the risks of hijacking.

So, open the Windows Settings and navigate to Apps > Apps & features. In the right pane, click on the Optional features link.

Windows 11

Windows 10

Now, check whether the OpenSSH Client is available on the list.

If it is not available on the list then click on the Add a feature button. Select OpenSSH Client from the list and then install it.

After proper installation, restart your computer to be sure.

In the next step, open Command Prompt. Once it opens, type the following command line and hit Enter.

ssh-keygen

At this time, the system will ask you to save the default location. You can do it by pressing the Enter key.You can also change the path as per your requirement. However, by default, it offers the location in the following form:

C:\users\<yourusername>\.ssh\id_rsa

After that, the system asks you to set a password (passphrase). While typing the password, you will not see anything but it gets recorded there. Next, enter the same password to confirm it.

If you want, you can continue without setting a password. To do so, just hit Enter key otherwise, type the passphrase there.

As you press the Enter key, the fingerprint for your key and SHA256 will appear. The default algorithm is RSA 2048.

The public key will be saved to the id_rsa.pub file. By default, it is located in the following form:

C:\users\<yourusername>\.ssh\id_rsa.pub

We recommend you not share the private SSH key (id_rsa) for obvious reasons.

I hope this guide would be helpful to generate SSH keys for your system.
