put-bucket-encryption

Description

Note

This operation is not supported by directory buckets.

This action uses the encryption subresource to configure default encryption and Amazon S3 Bucket Keys for an existing bucket.

By default, all buckets have a default encryption configuration that uses server-side encryption with Amazon S3 managed keys (SSE-S3). 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 . 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 does not validate the KMS key ID provided in PutBucketEncryption requests.

Warning

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

To use this operation, you must have permission to perform the s3:PutEncryptionConfiguration action. 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 Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide .

Options

--bucket (string)

Specifies default encryption for a bucket using server-side encryption with different key options. By default, all buckets have a default encryption configuration that uses server-side encryption with Amazon S3 managed keys (SSE-S3). You can optionally configure default encryption for a bucket by using server-side encryption with an Amazon Web Services KMS key (SSE-KMS) or a customer-provided key (SSE-C). For information about the bucket default encryption feature, see Amazon S3 Bucket Default Encryption 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.

--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.

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.

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.

KMSMasterKeyID -> (string)

Amazon Web Services Key Management Service (KMS) customer Amazon Web Services KMS key ID to use for the default encryption. 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 use a key ID, you can run into a LogDestination undeliverable error when creating a VPC flow log.

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 .

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. By default, S3 Bucket Key is not enabled.

For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide .

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).

--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.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

  • 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 configure server-side encryption for a bucket

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

aws s3api put-bucket-encryption \
    --bucket my-bucket \
    --server-side-encryption-configuration '{"Rules": [{"ApplyServerSideEncryptionByDefault": {"SSEAlgorithm": "AES256"}}]}'

This command produces no output.
