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


After an SSH key pair is deleted:

  • You cannot query the SSH key pair by calling the DescribeKeyPairs operation.
  • If the SSH key pair was bound to one or more ECS instances:
    • The key pair is no longer stored in Alibaba Cloud, but the instances can still use the key pair.
    • When you call the DescribeInstances operation to query information about an instance, the SSH key pair name (KeyPairNames) is still returned, but no other information is returned.


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.
