设置桶的加密配置
功能介绍
OBS使用PUT操作为桶创建或更新默认服务端加密配置信息。
设置桶加密配置后,在该桶中上传对象时,会采用桶的默认加密配置对数据进行加密。目前支持配置的服务端加密方式有:KMS托管密钥的服务端加密(SSE-KMS)、OBS托管密钥的服务端加密(SSE-OBS)。有关服务端加密方式的更多信息请参考服务端加密章节。
要使用此操作,您必须具有执行PutEncryptionConfiguration操作的权限。桶拥有者默认具有此权限,并且可以将此权限授予其他人。
有关权限控制的更多信息请参考《对象存储服务权限配置指南》的OBS权限控制概述章节。

请求消息参数
该请求消息中不使用消息参数。
请求消息头
该请求使用公共消息头,具体参见表3。
请求消息元素
在此请求中,需要在请求的消息体中配置桶的加密配置。桶加密的配置信息以XML格式上传。具体的配置元素如表1。
消息头名称 |
描述 |
是否必选 |
---|---|---|
ServerSideEncryptionConfiguration |
桶的默认加密配置的根元素。 类型:Container 父元素:无 子元素:Rule |
是 |
Rule |
桶的默认加密配置的子元素。 类型:Container 父元素:ServerSideEncryptionConfiguration 子元素:ApplyServerSideEncryptionByDefault |
是 |
ApplyServerSideEncryptionByDefault |
桶的默认加密配置的子元素。 类型:Container 父元素:Rule 子元素:SSEAlgorithm,KMSMasterKeyID |
是 |
SSEAlgorithm |
桶的默认加密配置要使用的服务端加密算法。 类型:String 有效值:
父元素:ApplyServerSideEncryptionByDefault |
是 |
KMSDataEncryption |
SSE-KMS加密方式下的数据加密算法。 类型:String 有效值:SM4 父元素:ApplyServerSideEncryptionByDefault |
否 |
KMSMasterKeyID |
SSE-KMS加密方式下使用的KMS主密钥,如果用户没有提供该头域,那么默认的主密钥将会被使用。 类型:String 有效值支持两种格式:
其中:
父元素:ApplyServerSideEncryptionByDefault |
否 |
ProjectID |
SSE-KMS加密方式下KMS主密钥所属的项目ID。如果KMS主密钥所属的项目为非默认项目,则需要通过该参数进行项目ID指定。 类型:String 有效值:
父元素:ApplyServerSideEncryptionByDefault
说明:
使用非默认IAM项目下的自定义密钥对桶内对象进行SSE-KMS加密,只有密钥拥有者可以对加密后的对象进行上传下载类操作,非密钥拥有者不能对加密后的对象进行上传下载类操作。 |
