Creates an SSH key pair. The system stores the public key and returns the unencrypted private key. The private key is encoded with PEM in the PKCS#8 format. You must properly store the private key and ensure its confidentiality.
Operation description
In addition to calling the CreateKeyPair operation to create a key pair, you can use a third-party tool to create a key pair and then call the ImportKeyPair operation to upload the key pair to an Alibaba Cloud region.
Up to 500 key pairs can be created in each region. For more information, see the "SSH key pair limits" section in Limits .
