AWS CLI version 2, the latest major version of AWS CLI, is now stable and recommended for general use. To view this page for the AWS CLI version 2, click here. For more information see the AWS CLI version 2 installation instructions and migration guide.
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). For information about the bucket default encryption feature, see Amazon S3 Bucket Default Encryption in the Amazon S3 User Guide .
To use this operation, you must have permission to perform the s3:GetEncryptionConfiguration
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 .
The following operations are related to GetBucketEncryption
:

--bucket
(string)
The name of the bucket from which the server-side encryption configuration is retrieved.
--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 code403 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.
--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.
--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.
--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.
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"
}
}
]
}
}
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
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 -> (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 toaws:kms
oraws: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 totrue
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 .
