put-bucket-encryption

Description

This implementation of the PUT operation uses the encryption subresource to set the default encryption state of an existing bucket.

This implementation of the PUT operation sets default encryption for a bucket using server-side encryption with Amazon S3-managed keys SSE-S3 or AWS KMS customer master keys (CMKs) (SSE-KMS). For information about the Amazon S3 default encryption feature, see Amazon S3 Default Bucket Encryption .

Warning

This operation requires AWS Signature Version 4. For more information, see Authenticating Requests (AWS Signature Version 4) .

To use this operation, you must have permissions 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 Simple Storage Service Developer Guide.

Synopsis

  put-bucket-encryption
--bucket <value>
[--content-md5 <value>]
--server-side-encryption-configuration <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options

--bucket (string)

Specifies default encryption for a bucket using server-side encryption with Amazon S3-managed keys (SSE-S3) or customer master keys stored in AWS KMS (SSE-KMS). For information about the Amazon S3 default encryption feature, see Amazon S3 Default Bucket Encryption in the Amazon Simple Storage Service Developer Guide .

--content-md5 (string)

The base64-encoded 128-bit MD5 digest of the server-side encryption configuration. This parameter is auto-populated when using the command from the CLI.

--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)

AWS Key Management Service (KMS) customer master 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 or the Amazon Resource Name (ARN) of the CMK. However, if you are using encryption with cross-account operations, you must use a fully qualified CMK ARN. For more information, see Using encryption for cross-account operations .

For example:

• Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

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

Warning

Amazon S3 only supports symmetric CMKs and not asymmetric CMKs. For more information, see Using Symmetric and Asymmetric Keys in the AWS Key Management Service Developer Guide .

JSON Syntax:

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

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples

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.

Output

None
