WebUsing supported checksum algorithms Amazon S3 offers you the option to choose the checksum algorithm that is used to validate your data during upload or download. You can select one of the following Secure Hash Algorithms (SHA) or Cyclic Redundancy Check (CRC) data-integrity check algorithms: CRC32 CRC32C SHA-1 SHA-256 WebCyclic Redundancy Check What is CRC? A type of checksum placed at the end of a data packet, which is used to check errors during the transmission of data. What is a checksum? A digit representing the sum of the correct digits in a piece of stored or transmitted digital data, against which later comparisons can be made to detect errors in the data.
