Encrypting S3 object with customer key (SSE-C)


I am trying to confirm that the S3 object encryption with Customer provided key (known as SSE-C) is currently (v4.57) not supported by AWS provider.

I looked at the documentation that provides examples for SSE-S3 and SSE-KMS but did not find SSE-C.

What is weird is that aws_s3_object_copy seems to support SSE-C for object source or destination of the copy (see customer_key)

Am I missing something ?
