Obtaining Bucket Encryption Configuration

Functions

OBS uses the GET method to obtain the encryption configuration of a specified bucket.

To perform this operation, you must have the GetEncryptionConfiguration permission. By default, only the bucket owner can delete the tags of a bucket. The bucket owner can allow other users to perform this operation by setting a bucket policy or granting them the permission.

For more information about permission control, see the permission control in the OBS Permission Configuration Guide.

Response Elements

This response contains the following elements to detail bucket encryption configuration:

**Table 1** Configuration elements of bucket encryption
Parameter	Type	Description
ServerSideEncryptionConfiguration	Container	Definition: Root element of the default bucket encryption configuration. ServerSideEncryptionConfiguration is the parent node of Rule. Range: None
Rule	Container	Definition: Child element of the default bucket encryption configuration. Rule is the parent node of ApplyServerSideEncryptionByDefault. Range: For details, see Rule parameters.

**Table 2** Rule parameter description
Parameter	Type	Description
ApplyServerSideEncryptionByDefault	Container	Definition: The child element of the default bucket encryption configuration. Range: For details, see Table 3.

**Table 3** ApplyServerSideEncryptionByDefault parameters
Parameter	Type	Description
SSEAlgorithm	String	Definition: Server-side encryption algorithm used for the default encryption configuration of a bucket. Range: kms: SSE-KMS encryption and the AES256 algorithm are used. AES256: SSE-OBS encryption and the AES256 algorithm are used.
KMSMasterKeyID	String	Definition: KMS master key ID used in SSE-KMS encryption. Range: regionID:domainID:key/key_id key_id In the preceding formats: regionID indicates the ID of the region where the key belongs. You can obtain the ID from Regions and Endpoints. domainID indicates the ID of the account to which the key belongs. For details, see Obtaining Account, IAM User, Project, User Group, Region, and Agency Information. key_id indicates the ID of the key created in DEW. For details about how to obtain the key ID, see Viewing a CMK.
ProjectID	String	Definition: ID of the project where the KMS master key belongs when SSE-KMS is used. Range: Project ID that matches KMSMasterKeyID, that is, the ID of the project to which the master key with the specified KMSMasterKeyID belongs
