  • Method Details

    • keyId

      GenerateDataKeyRequest.Builder keyId(String keyId)

      Specifies the symmetric encryption KMS key that encrypts the data key. You cannot specify an asymmetric KMS key or a KMS key in a custom key store. To get the type and origin of your KMS key, use the DescribeKey operation.

      To specify a KMS key, use its key ID, key ARN, alias name, or alias ARN. When using an alias name, prefix it with "alias/". To specify a KMS key in a different Amazon Web Services account, you must use the key ARN or alias ARN.

      For example:

      • Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

      • Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

      • Alias name: alias/ExampleAlias

      • Alias ARN: arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias

      To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey. To get the alias name and alias ARN, use ListAliases.

      Parameters:
      keyId - Specifies the symmetric encryption KMS key that encrypts the data key. You cannot specify an asymmetric KMS key or a KMS key in a custom key store. To get the type and origin of your KMS key, use the DescribeKey operation.

      To specify a KMS key, use its key ID, key ARN, alias name, or alias ARN. When using an alias name, prefix it with "alias/". To specify a KMS key in a different Amazon Web Services account, you must use the key ARN or alias ARN.

      For example:

      • Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

      • Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

      • Alias name: alias/ExampleAlias

      • Alias ARN: arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias

      To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey. To get the alias name and alias ARN, use ListAliases.

      Returns:
      Returns a reference to this object so that method calls can be chained together.

    • encryptionContext

      GenerateDataKeyRequest.Builder encryptionContext(Map<String,String> encryptionContext)

      Specifies the encryption context that will be used when encrypting the data key.

      Do not include confidential or sensitive information in this field. This field may be displayed in plaintext in CloudTrail logs and other output.

      An encryption context is a collection of non-secret key-value pairs that represent additional authenticated data. When you use an encryption context to encrypt data, you must specify the same (an exact case-sensitive match) encryption context to decrypt the data. An encryption context is supported only on operations with symmetric encryption KMS keys. On operations with symmetric encryption KMS keys, an encryption context is optional, but it is strongly recommended.

      For more information, see Encryption context in the Key Management Service Developer Guide.

      Parameters:
      encryptionContext - Specifies the encryption context that will be used when encrypting the data key.

    • recipient

      GenerateDataKeyRequest.Builder recipient(RecipientInfo recipient)

      A signed attestation document from an Amazon Web Services Nitro enclave and the encryption algorithm to use with the enclave's public key. The only valid encryption algorithm is RSAES_OAEP_SHA_256.

      This parameter only supports attestation documents for Amazon Web Services Nitro Enclaves. To include this parameter, use the Amazon Web Services Nitro Enclaves SDK or any Amazon Web Services SDK.

      When you use this parameter, instead of returning the plaintext data key, KMS encrypts the plaintext data key under the public key in the attestation document, and returns the resulting ciphertext in the CiphertextForRecipient field in the response. This ciphertext can be decrypted only with the private key in the enclave. The CiphertextBlob field in the response contains a copy of the data key encrypted under the KMS key specified by the KeyId parameter. The Plaintext field in the response is null or empty.

      For information about the interaction between KMS and Amazon Web Services Nitro Enclaves, see How Amazon Web Services Nitro Enclaves uses KMS in the Key Management Service Developer Guide.

      Parameters:
      recipient - A signed attestation document from an Amazon Web Services Nitro enclave and the encryption algorithm to use with the enclave's public key. The only valid encryption algorithm is RSAES_OAEP_SHA_256.

      This parameter only supports attestation documents for Amazon Web Services Nitro Enclaves. To include this parameter, use the Amazon Web Services Nitro Enclaves SDK or any Amazon Web Services SDK.

    • recipient

      default GenerateDataKeyRequest.Builder recipient(Consumer<RecipientInfo.Builder> recipient)

      This is a convenience method that creates an instance of the RecipientInfo.Builder avoiding the need to create one manually via RecipientInfo.builder().

      When the Consumer completes, SdkBuilder.build() is called immediately and its result is passed to recipient(RecipientInfo).

      Parameters:
      recipient - a consumer that will call methods on RecipientInfo.Builder
      Returns:
      Returns a reference to this object so that method calls can be chained together.
