NAME

Paws::KMS::ReEncrypt - Arguments for method ReEncrypt on Paws::KMS

DESCRIPTION

This class represents the parameters used for calling the method ReEncrypt on the AWS Key Management Service service. Use the attributes of this class as arguments to method ReEncrypt.

You shouldn't make instances of this class. Each attribute should be used as a named argument in the call to ReEncrypt.

SYNOPSIS

    my $kms = Paws->service('KMS');
    # To reencrypt data
    # The following example reencrypts data with the specified CMK.
    my $ReEncryptResponse = $kms->ReEncrypt(
      'CiphertextBlob'   => '<binary data>',
      'DestinationKeyId' => '0987dcba-09fe-87dc-65ba-ab0987654321'
    );
    # Results:
    my $CiphertextBlob = $ReEncryptResponse->CiphertextBlob;
    my $KeyId          = $ReEncryptResponse->KeyId;
    my $SourceKeyId    = $ReEncryptResponse->SourceKeyId;
    # Returns a L<Paws::KMS::ReEncryptResponse> object.

Values for attributes that are native types (Int, String, Float, etc) can passed as-is (scalar values). Values for complex Types (objects) can be passed as a HashRef. The keys and values of the hashref will be used to instance the underlying object. For the AWS API documentation, see <https://docs.aws.amazon.com/goto/WebAPI/kms/ReEncrypt>

ATTRIBUTES

REQUIRED CiphertextBlob => Str

Ciphertext of the data to reencrypt.

DestinationEncryptionAlgorithm => Str

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.

Valid values are: "SYMMETRIC_DEFAULT", "RSAES_OAEP_SHA_1", "RSAES_OAEP_SHA_256"

DestinationEncryptionContext => Paws::KMS::EncryptionContextType

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 (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#encrypt_context) in the AWS Key Management Service Developer Guide.

REQUIRED DestinationKeyId => Str

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, key 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.

GrantTokens => ArrayRef[Str|Undef]

A list of grant tokens.

Use a grant token when your permission to call this operation comes from a new grant that has not yet achieved eventual consistency. For more information, see Grant token (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#grant_token) in the AWS Key Management Service Developer Guide.

SourceEncryptionAlgorithm => Str

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.

Valid values are: "SYMMETRIC_DEFAULT", "RSAES_OAEP_SHA_1", "RSAES_OAEP_SHA_256"

SourceEncryptionContext => Paws::KMS::EncryptionContextType

Specifies the encryption context to use to decrypt the ciphertext. Enter the same encryption context that was used to encrypt the ciphertext.

For more information, see Encryption Context (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#encrypt_context) in the AWS Key Management Service Developer Guide.

SourceKeyId => Str

Specifies the customer master key (CMK) that AWS KMS will use to decrypt the ciphertext before it is re-encrypted. Enter a key ID of the CMK that was used to encrypt the ciphertext.

This parameter is required only when the ciphertext was encrypted under an asymmetric CMK. If you used a symmetric CMK, AWS KMS can get the CMK from metadata that it adds to the symmetric ciphertext blob. However, it is always recommended as a best practice. This practice ensures that you use the CMK that you intend.

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.
