1. API Description

Domain name for API request: cvm.intl.tencentcloudapi.com.

This API is used to associate key pairs with instances.

• If the public key of a key pair is written to the SSH configuration of the instance, users will be able to log in to the instance with the private key of the key pair.
• If the instance is already associated with a key, the old key will become invalid.
  If you currently use a password to log in, you will no longer be able to do so after you associate the instance with a key.
• Batch operations are supported. The maximum number of instances in each request is 100. If any instance in the request cannot be associated with a key, you will get an error code.

A maximum of 10 requests can be initiated per second for this API.
