Method Detail

ciphertextBlob

public final SdkBytes ciphertextBlob()

Ciphertext to be decrypted. The blob includes metadata.

Returns:

Ciphertext to be decrypted. The blob includes metadata.

hasEncryptionContext

public final boolean hasEncryptionContext()

Returns true if the EncryptionContext property was specified by the sender (it may be empty), or false if the sender did not specify the value (it will be empty). For responses returned by the SDK, the sender is the AWS service.

encryptionContext

public final Map<String,String> encryptionContext()

Specifies the encryption context to use when decrypting the data. An encryption context is valid only for cryptographic operations with a symmetric CMK. The standard asymmetric encryption algorithms that AWS KMS uses do not support an encryption context.

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.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

You can use hasEncryptionContext() to see if a value was sent in this field.

Returns:

Specifies the encryption context to use when decrypting the data. An encryption context is valid only for cryptographic operations with a symmetric CMK. The standard asymmetric encryption algorithms that AWS KMS uses do not support an encryption context.

hasGrantTokens

public final boolean hasGrantTokens()

Returns true if the GrantTokens property was specified by the sender (it may be empty), or false if the sender did not specify the value (it will be empty). For responses returned by the SDK, the sender is the AWS service.

grantTokens

public final List<String> grantTokens()

A list of grant tokens.

For more information, see Grant Tokens in the AWS Key Management Service Developer Guide.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

You can use hasGrantTokens() to see if a value was sent in this field.

Returns:

A list of grant tokens.

For more information, see Grant Tokens in the AWS Key Management Service Developer Guide.

keyId

public final String keyId()

Specifies the customer master key (CMK) that AWS KMS uses to decrypt the ciphertext. 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.

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.

Returns:

Specifies the customer master key (CMK) that AWS KMS uses to decrypt the ciphertext. 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.

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.

encryptionAlgorithm

public final EncryptionAlgorithmSpec encryptionAlgorithm()

Specifies the encryption algorithm that will be used to decrypt the ciphertext. Specify the same algorithm that was used to encrypt the data. If you specify a different algorithm, the Decrypt operation fails.

This parameter is required only when the ciphertext was encrypted under an asymmetric CMK. The default value, SYMMETRIC_DEFAULT, represents the only supported algorithm that is valid for symmetric CMKs.

If the service returns an enum value that is not available in the current SDK version, encryptionAlgorithm will return EncryptionAlgorithmSpec.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from encryptionAlgorithmAsString().

Returns:

Specifies the encryption algorithm that will be used to decrypt the ciphertext. Specify the same algorithm that was used to encrypt the data. If you specify a different algorithm, the Decrypt operation fails.

This parameter is required only when the ciphertext was encrypted under an asymmetric CMK. The default value, SYMMETRIC_DEFAULT, represents the only supported algorithm that is valid for symmetric CMKs.

encryptionAlgorithmAsString

public final String encryptionAlgorithmAsString()

Specifies the encryption algorithm that will be used to decrypt the ciphertext. Specify the same algorithm that was used to encrypt the data. If you specify a different algorithm, the Decrypt operation fails.

This parameter is required only when the ciphertext was encrypted under an asymmetric CMK. The default value, SYMMETRIC_DEFAULT, represents the only supported algorithm that is valid for symmetric CMKs.

Description copied from interface: ToCopyableBuilder

Take this object and create a builder that contains all of the current property values of this object.

Specified by:

toBuilder in interface ToCopyableBuilder<DecryptRequest.Builder,DecryptRequest>

Specified by:

equalsBySdkFields

public final boolean equalsBySdkFields(Object obj)

Description copied from interface: SdkPojo

Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

Description copied from class: SdkRequest

Used to retrieve the value of a field from any class that extends SdkRequest. The field name specified should match the member name from the corresponding service-2.json model specified in the codegen-resources folder for a given service. The class specifies what class to cast the returned value to. If the returned value is also a modeled class, the SdkRequest.getValueForField(String, Class) method will again be available.
