Hello,

I'm sorry but existing C++ SDK high-level encryption client does not have have "transfer manager" capabilities, so it is not perform multi-part upload/download.
We don't have any plans for this functionality at the moment either.

You maybe be interested in checking "Amazon S3 Encryption Client", but it is only implemented in java and go.

Thanks.
