Creating and Importing an SSH Key Pair

Function

This API is used to create an SSH key pair or import a public key to generate a key pair.

After a private SSH key is created, download the private key to a local directory. Then, you can use this private key to log in to the ECS. To ensure ECS security, the private key can be downloaded only once. Keep it secure.

Only the user that created the key pair can view it. If the key pair is created by an IAM user, the IAM account of the user and the other users of the same account cannot view the key pair.

URI

POST /v2.1/{project_id}/os-keypairs

Table 1 describes the parameters in the URI.

**Table 1** Parameter description
Parameter	Mandatory	Description
project_id	Yes	Specifies the project ID. For details about how to obtain the ID, see Obtaining a Project ID.

Request

Table 2 describes the request parameters.

When creating an SSH key, you only need to configure name. When importing an SSH key, you must configure public_key.

**Table 2** Request parameters
Parameter	Mandatory	Type	Description
keypair	Yes	Object	Specifies the created or imported SSH key pair. For details, see Table 3.

**Table 3** **keypair** field description
Parameter	Mandatory	Type	Description
public_key	No	String	Specifies the imported public key. It is recommended that the length of the imported public key be less than or equal to 1024 bytes. NOTE: If the length of the public key to be imported exceeds 1024 bytes, importing the public key will fail.
type	No	String	Specifies the key type. The value is ssh or x509. This parameter is supported in microversion 2.2 and later.
name	Yes	String	Specifies the key pair name. The new key pair name cannot be the same as an existing one.
user_id	No	String	Specifies the user ID of the key. This parameter is supported in microversion 2.10 and later.

Response

Table 4 describes the response parameters.

**Table 4** Response parameters
Parameter	Type	Description
keypair	Object	Specifies the SSH key pair. For details, see Table 5.

**Table 5** **keypair** field description
Parameter	Type	Description
fingerprint	String	Specifies fingerprint information about the key pair.
name	String	Specifies the key pair name.
public_key	String	Specifies information about the public key.
private_key	String	Specifies information about the private key. The information about the private key is contained in the response for creating an SSH key. The information about the private key is not contained in the response for importing an SSH key.
user_id	String	Specifies the ID of the user to which the key pair belongs.
type	String	Specifies the key type. The value is ssh or x509. This parameter is supported in microversion 2.2 and later.
