The default checksum algorithm is CRC32. Checksum behavior can be configured using `when_supported` and `when_required` options - in shared config using request_checksum_calculation, or as env variable using AWS_REQUEST_CHECKSUM_CALCULATION.\n\nThe S3 client attempts to validate response checksums for all S3 API operations that support checksums. However, if the SDK has not implemented the specified checksum algorithm then this validation is skipped. Checksum validation behavior can be configured using `when_supported` and `when_required` options - in shared config using response_checksum_validation, or as env variable using AWS_RESPONSE_CHECKSUM_VALIDATION.\n",
