                    _members

Declaration

Swift

public static var _members: [AWSShapeMember]


                    
                    
                    ciphertextBlob

Ciphertext of the data to reencrypt.

Declaration

Swift

public let ciphertextBlob: Data


                    
                    
                    destinationEncryptionAlgorithm

Specifies the encryption algorithm that AWS KMS will use to reecrypt the data after it has decrypted it. The default value, SYMMETRIC_DEFAULT, represents the encryption algorithm used for symmetric CMKs. This parameter is required only when the destination CMK is an asymmetric CMK.

Declaration

Swift

public let destinationEncryptionAlgorithm: EncryptionAlgorithmSpec?


                    
                    
                    destinationEncryptionContext

Specifies that encryption context to use when the reencrypting the data. A destination encryption context is valid only when the destination CMK is a symmetric CMK. The standard ciphertext format for asymmetric CMKs does not include fields for metadata. An encryption context is a collection of non-secret key-value pairs that represents 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 optional when encrypting with a symmetric CMK, but it is highly recommended. For more information, see Encryption Context in the AWS Key Management Service Developer Guide.

Declaration

Swift

public let destinationEncryptionContext: [String : String]?


                    
                    
                    destinationKeyId

A unique identifier for the CMK that is used to reencrypt the data. Specify a symmetric or asymmetric CMK with a KeyUsage value of ENCRYPT_DECRYPT. To find the KeyUsage value of a CMK, use the DescribeKey operation. To specify a CMK, use its key ID, Amazon Resource Name (ARN), alias name, or alias ARN. When using an alias name, prefix it with “alias/”. To specify a CMK in a different AWS 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 CMK, use ListKeys or DescribeKey. To get the alias name and alias ARN, use ListAliases.

Declaration

Swift

public let destinationKeyId: String


                    
                    
                    grantTokens

A list of grant tokens. For more information, see Grant Tokens in the AWS Key Management Service Developer Guide.

Declaration

Swift

public let grantTokens: [String]?


                    
                    
                    sourceEncryptionAlgorithm

Specifies the encryption algorithm that AWS KMS will use to decrypt the ciphertext before it is reencrypted. The default value, SYMMETRIC_DEFAULT, represents the algorithm used for symmetric CMKs. Specify the same algorithm that was used to encrypt the ciphertext. If you specify a different algorithm, the decrypt attempt fails. This parameter is required only when the ciphertext was encrypted under an asymmetric CMK.

Declaration

Swift

public let sourceEncryptionAlgorithm: EncryptionAlgorithmSpec?


                    
                    
                    sourceEncryptionContext

Specifies the encryption context to use to decrypt the ciphertext. Enter the same encryption context that was used to encrypt the ciphertext. An encryption context is a collection of non-secret key-value pairs that represents 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 optional when encrypting with a symmetric CMK, but it is highly recommended. For more information, see Encryption Context in the AWS Key Management Service Developer Guide.

Declaration

Swift

public let sourceEncryptionContext: [String : String]?


                    
                    
                    sourceKeyId

A unique identifier for the CMK that is used to decrypt the ciphertext before it reencrypts it using the destination CMK. This parameter is required only when the ciphertext was encrypted under an asymmetric CMK. Otherwise, AWS KMS uses the metadata that it adds to the ciphertext blob to determine which CMK was used to encrypt the ciphertext. However, you can use this parameter to ensure that a particular CMK (of any kind) is used to decrypt the ciphertext before it is reencrypted. If you specify a KeyId value, the decrypt part of the ReEncrypt operation succeeds only if the specified CMK was used to encrypt the ciphertext. To specify a CMK, use its key ID, Amazon Resource Name (ARN), alias name, or alias ARN. When using an alias name, prefix it with “alias/”. 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 CMK, use ListKeys or DescribeKey. To get the alias name and alias ARN, use ListAliases.
