Method Detail

keyId

public final String keyId()

Identifies an asymmetric KMS key. KMS uses the private key in the asymmetric KMS key to sign the message. The KeyUsage type of the KMS key must be SIGN_VERIFY. To find the KeyUsage of a 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:

• 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.

message

public final SdkBytes message()

Specifies the message or message digest to sign. Messages can be 0-4096 bytes. To sign a larger message, provide the message digest.

If you provide a message, KMS generates a hash digest of the message and then signs it.

Returns:

Specifies the message or message digest to sign. Messages can be 0-4096 bytes. To sign a larger message, provide the message digest.

If you provide a message, KMS generates a hash digest of the message and then signs it.

messageType

public final MessageType messageType()

Tells KMS whether the value of the Message parameter is a message or message digest. The default value, RAW, indicates a message. To indicate a message digest, enter DIGEST.

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

Returns:

Tells KMS whether the value of the Message parameter is a message or message digest. The default value, RAW, indicates a message. To indicate a message digest, enter DIGEST.

MessageType

messageTypeAsString

public final String messageTypeAsString()

Tells KMS whether the value of the Message parameter is a message or message digest. The default value, RAW, indicates a message. To indicate a message digest, enter DIGEST.

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

Returns:

Tells KMS whether the value of the Message parameter is a message or message digest. The default value, RAW, indicates a message. To indicate a message digest, enter DIGEST.

MessageType

hasGrantTokens

public final boolean hasGrantTokens()

For responses, this returns true if the service returned a value for the GrantTokens property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

grantTokens

public final List<String> grantTokens()

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 and Using a grant token in the Key Management Service Developer Guide.

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

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasGrantTokens() method.

Returns:

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 and Using a grant token in the Key Management Service Developer Guide.

signingAlgorithm

public final SigningAlgorithmSpec signingAlgorithm()

Specifies the signing algorithm to use when signing the message.

Choose an algorithm that is compatible with the type and size of the specified asymmetric KMS key.

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

Returns:

Specifies the signing algorithm to use when signing the message.

Choose an algorithm that is compatible with the type and size of the specified asymmetric KMS key.

See Also:

SigningAlgorithmSpec

signingAlgorithmAsString

public final String signingAlgorithmAsString()

Specifies the signing algorithm to use when signing the message.

Choose an algorithm that is compatible with the type and size of the specified asymmetric KMS key.

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

Returns:

Specifies the signing algorithm to use when signing the message.

Choose an algorithm that is compatible with the type and size of the specified asymmetric KMS key.

toBuilder

public SignRequest.Builder toBuilder()

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<SignRequest.Builder,SignRequest>

Specified by:

toBuilder in class KmsRequest

Returns:

a builder for type T

builder

public static SignRequest.Builder builder()

serializableBuilderClass

public static Class<? extends SignRequest.Builder> serializableBuilderClass()

hashCode

public final int hashCode()

Overrides:

hashCode in class AwsRequest

equals

public final boolean equals(Object obj)

Overrides:

equals in class AwsRequest

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.

Specified by:

equalsBySdkFields in interface SdkPojo

Parameters:

obj - the object to be compared with

Returns:

true if the other object equals to this object by sdk fields, false otherwise.

toString

public final String toString()

Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.

Overrides:

toString in class Object

getValueForField

public final <T> Optional<T> getValueForField(String fieldName,
                                              Class<T> clazz)

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.

Overrides:

getValueForField in class SdkRequest

Parameters:

fieldName - The name of the member to be retrieved.

clazz - The class to cast the returned object to.

Returns:

Optional containing the casted return value

sdkFields

public final List<SdkField<?>> sdkFields()

Specified by:

sdkFields in interface SdkPojo

Returns:

List of SdkField in this POJO. May be empty list but should never be null.
