Issue #, if available:

Low-level aws s3api commands support checksums other than MD5 for verifying end-to-end data integrity. This pull request ports over similar functionality to high-level aws s3 commands.

Description of changes:

  • Added --checksum-algorithm flag for file uploads using aws s3 cp, aws s3 sync, and aws s3 mv.
    • Supported algorithms are CRC32, SHA256, SHA1, CRC32C.
  • Added --checksum-mode flag for file downloads using aws s3 cp, aws s3 sync, and aws s3 mv.
  • Added unit and functional tests to assert the correctness of these changes.
