copySourceSseCustomerKeyMd5

Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

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.
