Struct ServerSideEncryptionByDefault

Source 
#[non_exhaustive]
pub struct ServerSideEncryptionByDefault {
    pub sse_algorithm: ServerSideEncryption,
    pub kms_master_key_id: Option<String>,
}
Expand description

Describes 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. For more information, see PutBucketEncryption.

  • General purpose buckets - If you don't specify a customer managed key at configuration, Amazon S3 automatically creates an Amazon Web Services KMS key (aws/s3) in your Amazon Web Services account the first time that you add an object encrypted with SSE-KMS to a bucket. By default, Amazon S3 uses this KMS key for SSE-KMS.

  • Directory buckets - 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.

  • Directory buckets - For directory buckets, there are only two supported options for server-side encryption: SSE-S3 and SSE-KMS.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§sse_algorithm: ServerSideEncryption

Server-side encryption algorithm to use for the default encryption.

For directory buckets, there are only two supported values for server-side encryption: AES256 and aws:kms.

§kms_master_key_id: Option<String>

Amazon Web Services Key Management Service (KMS) customer managed key ID to use for the default encryption.

  • 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.

  • 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.

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.
