    This API is used to create an OpenSSH RSA key pair, which you can use to log in to a Linux instance.

    • The name of the key pair must be unique.
    • You can save the private key to a file and use it as an authentication method for SSH.
    • Tencent Cloud does not save users' private keys. Be sure to save it yourself.
