You can call this operation to delete one or more SSH key pairs.


After you delete an SSH key pair, take note of the following items:

  • You cannot query the SSH key pair by calling the DescribeKeyPairs operation.
  • If an ECS instance has been bound with this SSH key pair,
    • Alibaba Cloud no longer stores the SSH key pair for you, but the instance can use the SSH key pair normally.
    • When you call the DescribeInstances operation to query instance information, the SSH key pair name (KeyPairNames) is still returned, but without other information.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
