sseCustomerAlgorithm

Specifies the algorithm to use when encrypting the object (for example, AES256).

When you perform a CopyObject operation, if you want to use a different type of encryption setting for the target object, you can specify appropriate encryption-related headers to encrypt the target object with an Amazon S3 managed key, a KMS key, or a customer-provided key. If the encryption setting in your request is different from the default encryption configuration of the destination bucket, the encryption setting in your request takes precedence.

This functionality is not supported when the destination bucket is a directory bucket.
