Struct aws_sdk_kms::client::fluent_builders::DescribeKey

pub struct DescribeKey<C = DynConnector, M = DefaultMiddleware, R = Standard> { /* private fields */ }

Fluent builder constructing a request to DescribeKey.

Provides detailed information about a KMS key. You can run DescribeKey on a customer managed key or an Amazon Web Services managed key.

This detailed information includes the key ARN, creation date (and deletion date, if applicable), the key state, and the origin and expiration date (if any) of the key material. It includes fields, like KeySpec, that help you distinguish symmetric from asymmetric KMS keys. It also provides information that is particularly important to asymmetric keys, such as the key usage (encryption or signing) and the encryption algorithms or signing algorithms that the KMS key supports. For KMS keys in custom key stores, it includes information about the custom key store, such as the key store ID and the CloudHSM cluster ID. For multi-Region keys, it displays the primary key and all related replica keys.

DescribeKey does not return the following information:

• Aliases associated with the KMS key. To get this information, use ListAliases.

• Whether automatic key rotation is enabled on the KMS key. To get this information, use GetKeyRotationStatus. Also, some key states prevent a KMS key from being automatically rotated. For details, see How Automatic Key Rotation Works in Key Management Service Developer Guide.

• Tags on the KMS key. To get this information, use ListResourceTags.

• Key policies and grants on the KMS key. To get this information, use GetKeyPolicy and ListGrants.

If you call the DescribeKey operation on a predefined Amazon Web Services alias, that is, an Amazon Web Services alias with no key ID, KMS creates an Amazon Web Services managed key. Then, it associates the alias with the new KMS key, and returns the KeyId and Arn of the new KMS key in the response.

Cross-account use: Yes. To perform this operation with a KMS key in a different Amazon Web Services account, specify the key ARN or alias ARN in the value of the KeyId parameter.

Required permissions: kms:DescribeKey (key policy)

Implementations

impl<C, M, R> DescribeKey<C, M, R> where
    C: SmithyConnector,
    M: SmithyMiddleware<C>,
    R: NewRequestPolicy, 

pub async fn send(self) -> Result<DescribeKeyOutput, SdkError<DescribeKeyError>> where
    R::Policy: SmithyRetryPolicy<DescribeKeyInputOperationOutputAlias, DescribeKeyOutput, DescribeKeyError, DescribeKeyInputOperationRetryAlias>, 

Sends the request and returns the response.

If an error occurs, an SdkError will be returned with additional details that can be matched against.

By default, any retryable failures will be retried twice. Retry behavior is configurable with the RetryConfig, which can be set when configuring the client.

pub fn key_id(self, input: impl Into<String>) -> Self

Describes the specified KMS key.

If you specify a predefined Amazon Web Services alias (an Amazon Web Services alias with no key ID), KMS associates the alias with an Amazon Web Services managed key and returns its KeyId and Arn in the response.

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.

pub fn set_key_id(self, input: Option<String>) -> Self

Describes the specified KMS key.

If you specify a predefined Amazon Web Services alias (an Amazon Web Services alias with no key ID), KMS associates the alias with an Amazon Web Services managed key and returns its KeyId and Arn in the response.

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.

pub fn grant_tokens(self, input: impl Into<String>) -> Self

Appends an item to GrantTokens.

To override the contents of this collection use set_grant_tokens.

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.

pub fn set_grant_tokens(self, input: Option<Vec<String>>) -> Self

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.
