Choose two
  • A The REST API request contains a base64-encoded signature of the message content and headers.
  • B The REST API request message body is encoded as a SHA384 hash and then signed with the API Key ID.
  • C The Cisco Intersight Web service verifies the signature of incoming request with the RSA public key for the API Key ID.
  • D The incoming REST API request is challenged by the Cisco Intersight Web service with a request for the RSA private key.
  • E The message body is encoded as a SHA256 hash if the message body is not empty and then signed with the API Key ID.
Explanation

Cisco Intersight API-key authentication uses an HTTP signature that covers request headers and body and is Base64-encoded for transmission. The service verifies an incoming request by locating the public key associated with the specified API key ID; the client retains its private key.
