get-bucket-encryption

Description

Returns the default encryption configuration for an Amazon S3 bucket. By default, all buckets have a default encryption configuration that uses server-side encryption with Amazon S3 managed keys (SSE-S3).

Note

Permissions

  • General purpose bucket permissions - The s3:GetEncryptionConfiguration permission is required in a policy. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Operations and Managing Access Permissions to Your Amazon S3 Resources .

  • Directory bucket permissions - To grant access to this API operation, you must have the s3express:GetEncryptionConfiguration permission in an IAM identity-based policy instead of a bucket policy. Cross-account access to this API operation isn't supported. This operation can only be performed by the Amazon Web Services account that owns the resource. For more information about directory bucket policies and permissions, see Amazon Web Services Identity and Access Management (IAM) for S3 Express One Zone in the Amazon S3 User Guide .

    HTTP Host header syntax

Directory buckets - The HTTP Host header syntax is s3express-control.*region* .amazonaws.com .

Options

--bucket (string)

The name of the bucket from which the server-side encryption configuration is retrieved.

Directory buckets - When you use this operation with a directory bucket, you must use path-style requests in the format https://s3express-control.*region_code* .amazonaws.com/*bucket-name* `` . Virtual-hosted-style requests aren't supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must also follow the format `` *bucket_base_name* --*az_id* --x-s3 (for example, `` DOC-EXAMPLE-BUCKET --usw2-az1 --x-s3`` ). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide

--expected-bucket-owner (string)

The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

Note

For directory buckets, this header is not supported in this API operation. If you specify this header, the request fails with the HTTP status code 501 Not Implemented .

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To retrieve the server-side encryption configuration for a bucket

The following get-bucket-encryption example retrieves the server-side encryption configuration for the bucket my-bucket.

aws s3api get-bucket-encryption \
    --bucket my-bucket

Output:

{
    "ServerSideEncryptionConfiguration": {
        "Rules": [
            {
                "ApplyServerSideEncryptionByDefault": {
                    "SSEAlgorithm": "AES256"
                }
            }
        ]
    }
}

Output

ServerSideEncryptionConfiguration -> (structure)

Specifies the default server-side-encryption configuration.

Rules -> (list)

Container for information about a particular server-side encryption configuration rule.

(structure)

Specifies the default server-side encryption configuration.

Note

  • General purpose buckets - If you're specifying a customer managed KMS key, we recommend using a fully qualified KMS key ARN. If you use a KMS key alias instead, then KMS resolves the key within the requester’s account. This behavior can result in data that's encrypted with a KMS key that belongs to the requester, and not the bucket owner.
  • Directory buckets - When you specify an KMS customer managed key for encryption in your directory bucket, only use the key ID or key ARN. The key alias format of the KMS key isn't supported.

ApplyServerSideEncryptionByDefault -> (structure)

Specifies the default server-side encryption to apply to new objects in the bucket. If a PUT Object request doesn't specify any server-side encryption, this default encryption will be applied.

SSEAlgorithm -> (string)

Server-side encryption algorithm to use for the default encryption.

Note

For directory buckets, there are only two supported values for server-side encryption: AES256 and aws:kms .

KMSMasterKeyID -> (string)

Amazon Web Services Key Management Service (KMS) customer managed key ID to use for the default encryption.

Note

  • General purpose buckets - This parameter is allowed if and only if SSEAlgorithm is set to aws:kms or aws:kms:dsse .
  • Directory buckets - This parameter is allowed if and only if SSEAlgorithm is set to aws:kms .

You can specify the key ID, key alias, or the Amazon Resource Name (ARN) of the KMS key.

  • Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab
  • Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab
  • Key Alias: alias/alias-name

If you are using encryption with cross-account or Amazon Web Services service operations, you must use a fully qualified KMS key ARN. For more information, see Using encryption for cross-account operations .

Note

  • General purpose buckets - If you're specifying a customer managed KMS key, we recommend using a fully qualified KMS key ARN. If you use a KMS key alias instead, then KMS resolves the key within the requester’s account. This behavior can result in data that's encrypted with a KMS key that belongs to the requester, and not the bucket owner. Also, if you use a key ID, you can run into a LogDestination undeliverable error when creating a VPC flow log.
  • Directory buckets - When you specify an KMS customer managed key for encryption in your directory bucket, only use the key ID or key ARN. The key alias format of the KMS key isn't supported.

Warning

Amazon S3 only supports symmetric encryption KMS keys. For more information, see Asymmetric keys in Amazon Web Services KMS in the Amazon Web Services Key Management Service Developer Guide .

BucketKeyEnabled -> (boolean)

Specifies whether Amazon S3 should use an S3 Bucket Key with server-side encryption using KMS (SSE-KMS) for new objects in the bucket. Existing objects are not affected. Setting the BucketKeyEnabled element to true causes Amazon S3 to use an S3 Bucket Key.

Note

  • General purpose buckets - By default, S3 Bucket Key is not enabled. For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide .
  • Directory buckets - S3 Bucket Keys are always enabled for GET and PUT operations in a directory bucket and can’t be disabled. S3 Bucket Keys aren't supported, when you copy SSE-KMS encrypted objects from general purpose buckets to directory buckets, from directory buckets to general purpose buckets, or between directory buckets, through CopyObject , UploadPartCopy , the Copy operation in Batch Operations , or the import jobs . In this case, Amazon S3 makes a call to KMS every time a copy request is made for a KMS-encrypted object.
