copySourceSseCustomerKey

Specifies the customer-provided encryption key for Amazon S3 to use to decrypt the source object. The encryption key provided in this header must be the same one that was used when the source object was created.

If the source object for the copy is stored in Amazon S3 using SSE-C, you must provide the necessary encryption information in your request so that Amazon S3 can decrypt the object for copying.

This functionality is not supported when the source object is in a directory bucket.
