所以我正在运行一个Aurora活动流，它似乎创建了一个Kinesis流。我正在尝试通过以下命令使用aws cli工具读取流：
aws kinesis get-shard-iterator --shard-id shardId-000000000 --shard-iterator-type TRIM_HORIZON --stream-name <name of kinesis stream> --profile sandbox
aws kinesis get-records --shard-iterator <some long iterator> --profile sandbox
我得到了这些记录：

为什么所有这些都在“数据”下加密？ Aurora是这样做还是Kinesis？
如何解密数据？
