The CLUSCTL_RESOURCE_ADD_CRYPTO_CHECKPOINT resource control code associates a cryptographic key checkpoint, as specified in section 220.127.116.11.1.1, with the designated resource.
The client MUST provide the location of the cryptographic keys, as specified in section 18.104.22.168.1.1, in the buffer that is designated by lpInBuffer.
After successful completion of the method, the server SHOULD NOT write any data to the buffer that is designated by lpOutBuffer.
The server MUST restore the cryptographic key on the node hosting the resource prior to bringing the resource online. The server MAY choose to detect changes in the checkpointed data and take another checkpoint of the data associated with the resource.
