ciphertextForRecipient

The plaintext shared secret encrypted with the public key from the attestation document. This ciphertext can be decrypted only by using a private key from the attested environment.

This field is included in the response only when the Recipient parameter in the request includes a valid attestation document from an Amazon Web Services Nitro enclave or NitroTPM. For information about the interaction between KMS and Amazon Web Services Nitro Enclaves or Amazon Web Services NitroTPM, see Cryptographic attestation support in KMS in the Key Management Service Developer Guide.
