Introduction to the use of SSH KEY

The main purpose of SSH Key in public cloud networks is to provide users with a secure and convenient way to access cloud servers. Unlike traditional password login methods, SSH keys use a pair of keys (public key and private key) for identity authentication, which greatly enhances security. Users upload the public key to the cloud server and save the private key locally. Each time you log in, the private key is matched with the public key for verification, without the need to enter a password, thus avoiding the risk of password leakage. In public cloud environments, SSH Key is often used for automated scripts, batch management of cloud servers, and remote access and management of instances to ensure encryption and security of communications. Therefore, SSH Key can improve security and reduce operational complexity, and is a common authentication method in cloud environments.

Create an SSH Key

After logging in to the raksmart system, select the menu My Services → Public Cloud → SSH Public Key from the left column, and you will see the interface for creating an SSH public key, as shown below.

如果您想创建新的SSH 公钥，请点击按钮“添加”，如下创建公钥的对话框会被打开。填写公钥名称， 比如“my-ssh-key”，把您的公钥字符串通过拷贝/粘贴的方式到如下对话框里的相应部分，并点击按钮“保存”， 以便保存该SSH公钥。

SH KEY 的删除

对于已经有的SSH公钥，如果您希望删除它，你可以点击每个SSH公钥后边的按钮“删除”，然后点击按钮“OK”，该SSH公钥将会被删除。

SSH KEY 的应用

在购买服务中心购买新主机（购买服务->公有云->公有云）时，您会看到一个关于新主机的配置页面。其中有登录方式（密码和公钥）的选项。如下图所示：

如果希望使用公钥登录，请选择选项“公钥”， 然后从SSH公钥下拉选项里，选择您创建的公钥，比如“my-ssh-key”。 这样您在购买该主机后，就可以通过SSH 公钥的方式登录该主机。
