// Returns a random byte string that is cryptographically secure. You must use the
// NumberOfBytes parameter to specify the length of the random byte string. There
// is no default value for string length. By default, the random byte string is
// generated in KMS. To generate the byte string in the CloudHSM cluster associated
// with an CloudHSM key store, use the CustomKeyStoreId parameter. GenerateRandom
// also supports Amazon Web Services Nitro Enclaves (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/nitro-enclave.html)
// , which provide an isolated compute environment in Amazon EC2. To call
// GenerateRandom for a Nitro enclave, use the Amazon Web Services Nitro Enclaves
// SDK (https://docs.aws.amazon.com/enclaves/latest/user/developing-applications.html#sdk)
// or any Amazon Web Services SDK. Use the Recipient parameter to provide the
// attestation document for the enclave. Instead of plaintext bytes, the response
// includes the plaintext bytes encrypted under the public key from the attestation
// document ( CiphertextForRecipient ).For information about the interaction
// between KMS and Amazon Web Services Nitro Enclaves, see How Amazon Web Services
// Nitro Enclaves uses KMS (https://docs.aws.amazon.com/kms/latest/developerguide/services-nitro-enclaves.html)
// in the Key Management Service Developer Guide. For more information about
// entropy and random number generation, see Key Management Service Cryptographic
// Details (https://docs.aws.amazon.com/kms/latest/cryptographic-details/) .

NumberOfBytes *int32
// A signed attestation document (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/nitro-enclave-how.html#term-attestdoc)

// Web Services Nitro Enclaves SDK (https://docs.aws.amazon.com/enclaves/latest/user/developing-applications.html#sdk)

// returning plaintext bytes, KMS encrypts the plaintext bytes under the public key

// CiphertextForRecipient field in the response. This ciphertext can be decrypted
// only with the private key in the enclave. The Plaintext field in the response
