S3 / Client / put_bucket_encryption

put_bucket_encryption#

S3.Client.put_bucket_encryption(**kwargs)#

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

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).

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.

Parameters:

  • Bucket (string) –

    [REQUIRED]

    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.

  • ContentMD5 (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.

  • ChecksumAlgorithm (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.

  • ServerSideEncryptionConfiguration (dict) –

    [REQUIRED]

    Specifies the default server-side-encryption configuration.

    • Rules (list) – [REQUIRED]

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

      • (dict) –

        Specifies the default server-side encryption configuration.

        Note

        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.

        • ApplyServerSideEncryptionByDefault (dict) –

          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) – [REQUIRED]

            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 or aws:kms:dsse.

            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.

  • ExpectedBucketOwner (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).

Returns:

None
