put-bucket-encryption¶

Description¶

This operation configures default encryption and Amazon S3 Bucket Keys for an existing bucket.

Note

Directory buckets - For directory buckets, you must make requests for this API operation to the Regional endpoint. These endpoints support path-style requests in the format ``https://s3express-control.*region_code* .amazonaws.com/bucket-name `` . Virtual-hosted-style requests aren’t supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide .

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

Note

General purpose buckets
- You can optionally configure default encryption for a bucket by using server-side encryption with Key Management Service (KMS) keys (SSE-KMS) or dual-layer server-side encryption with Amazon Web Services KMS keys (DSSE-KMS). If you specify default encryption by using SSE-KMS, you can also configure Amazon S3 Bucket Keys . For information about the bucket default encryption feature, see Amazon S3 Bucket Default Encryption in the Amazon S3 User Guide .
- If you use PutBucketEncryption to set your default bucket encryption to SSE-KMS, you should verify that your KMS key ID is correct. Amazon S3 doesn’t validate the KMS key ID provided in PutBucketEncryption requests.
Directory buckets - You can optionally configure default encryption for a bucket by using server-side encryption with Key Management Service (KMS) keys (SSE-KMS).
- We recommend that the bucket’s default encryption uses the desired encryption configuration and you don’t override the bucket default encryption in your CreateSession requests or PUT object requests. Then, new objects are automatically encrypted with the desired encryption settings. For more information about the encryption overriding behaviors in directory buckets, see Specifying server-side encryption with KMS for new object uploads .
- Your SSE-KMS configuration can only support 1 customer managed key per directory bucket for the lifetime of the bucket. The Amazon Web Services managed key (aws/s3 ) isn’t supported.
- 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.
- 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.
- For directory buckets, if you use PutBucketEncryption to set your default bucket encryption to SSE-KMS, Amazon S3 validates the KMS key ID provided in PutBucketEncryption requests.

Warning

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, this action requires Amazon Web Services Signature Version 4. For more information, see Authenticating Requests (Amazon Web Services Signature Version 4) .

Permissions

General purpose bucket permissions - The s3:PutEncryptionConfiguration 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 in the Amazon S3 User Guide .
Directory bucket permissions - To grant access to this API operation, you must have the s3express:PutEncryptionConfiguration 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 . To set a directory bucket default encryption with SSE-KMS, you must also have the kms:GenerateDataKey and the kms:Decrypt permissions in IAM identity-based policies and KMS key policies for the target KMS key.

HTTP Host header syntax

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

Options¶

--bucket (string)

Specifies default encryption for a bucket using server-side encryption with different key options.

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

--content-md5 (string)

The base64-encoded 128-bit MD5 digest of the server-side encryption configuration.

For requests made using the Amazon Web Services Command Line Interface (CLI) or Amazon Web Services SDKs, this field is calculated automatically.

Note
This functionality is not supported for directory buckets.

--checksum-algorithm (string)

Indicates the algorithm used to create the checksum for the object when you use the SDK. This header will not provide any additional functionality if you don’t use the SDK. When you send this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request . For more information, see Checking object integrity in the Amazon S3 User Guide .

If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

Note
For directory buckets, when you use Amazon Web Services SDKs, CRC32 is the default checksum algorithm that’s used for performance.

Possible values:

CRC32

CRC32C

SHA1

SHA256

--server-side-encryption-configuration (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.

JSON Syntax:

{
  "Rules": [
    {
      "ApplyServerSideEncryptionByDefault": {
        "SSEAlgorithm": "AES256"|"aws:kms"|"aws:kms:dsse",
        "KMSMasterKeyID": "string"
      },
      "BucketKeyEnabled": true|false
    }
    ...
  ]
}

--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 | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

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
yaml
yaml-stream

--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.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

base64
raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

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 configure server-side encryption for a bucket

The following put-bucket-encryption example sets AES256 encryption as the default for the specified bucket.
