要查看补助金 Amazon KMS钥匙

以下list-grants示例显示了指定的所有授权 Amazon 您账户中的亚马逊 DynamoDB 托管KMS密钥。该授权允许 DynamoDB 在将 DynamoDB 表写入磁盘之前代表您使用KMS密钥对其进行加密。你可以使用这样的命令来查看上面的授权 Amazon 托管KMS密钥和客户管理的KMS密钥在 Amazon 账户和区域。

此命令使用带有密钥 ID 的key-id参数来标识KMS密钥。您可以使用密钥 ID 或密钥ARN来识别KMS密钥。获取密钥 ID 或ARN密钥 Amazon 托管KMS密钥，使用list-keys或list-aliases命令。

aws kms list-grants \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab

输出显示，该授权授予了 Amazon DynamoDB 使用KMS密钥进行加密操作的权限，并允许其查看有关KMS密钥的详细信息 DescribeKey () 和停用授权 ()。RetireGrantEncryptionContextSubset 约束将这些权限限制为包含指定加密上下文对的请求。因此，授权中的权限仅对指定账户和 DynamoDB 表有效。
