Multipart upload for EncryptionV2

[Seitanas]

Hello, is there any way to initiate multipart upload using Aws::S3::EncryptionV2::Client ? Getting error:

undefined method `create_multipart_upload' for #<Aws::S3::EncryptionV2::Client

Thank you.

It's not supported. There are some technical limitations and challenges involved.

Unfortunately we don't support multipart upload with client side encryption. There are additional complexities to ensure that client side encryption applied to multipart upload is both secure and correct.

I'd recommend breaking your file apart, doing put_object on each part and then manually recombining them. Alternatively, depending on your encryption needs, you can use server side encryption which will work seamlessly with multipart uploads.

Thank you for information. I just went on with reading encrypted datastream from openssl in chunks and uploading them as multipart data.

@Seitanas Can you share a code sample of reading encrypted datastream from openssl in chunks and uploading them as multipart data?
