checksum property

String? checksum
final

The checksum of the data in the response. This header is returned only when retrieving the output for an archive retrieval job. Furthermore, this header appears only under the following conditions:

  • You get the entire range of the archive.
  • You request a range to return of the archive that starts and ends on a multiple of 1 MB. For example, if you have an 3.1 MB archive and you specify a range to return that starts at 1 MB and ends at 2 MB, then the x-amz-sha256-tree-hash is returned as a response header.
  • You request a range of the archive to return that starts on a multiple of 1 MB and goes to the end of the archive. For example, if you have a 3.1 MB archive and you specify a range that starts at 2 MB and ends at 3.1 MB (the end of the archive), then the x-amz-sha256-tree-hash is returned as a response header.
